Chapter 1: Scripture --- The Sermon in Its Biblical Context

Overview

This chapter examines the Sermon on the Mount (Matthew 5—7) with the care it deserves: passage by passage, word by word, in Greek and in context. The question is not merely what the Sermon says --- most Christians agree on its content --- but whether the Sermon is binding instruction for all believers in every age, or whether its audience and dispensational setting limit its direct application to the church today.

Key Principle: The question “is the Sermon on the Mount for believers today?” cannot be answered by quoting a few verses. It requires examining the Sermon’s audience, its relationship to the Mosaic Law, the meaning of “fulfil” in Matthew 5:17, the scope of the Great Commission in Matthew 28:18—20, and the extensive echoes of the Sermon throughout the rest of the New Testament. All of those layers are addressed here.

The Literary Context: Five Discourses in Matthew’s Gospel

The Sermon on the Mount is the first of five major teaching blocks in Matthew, each ending with a formulaic transition (“and it came to pass, when Jesus had ended these sayings…”):

Discourse	Chapters	Theme	Concluding Formula
1. Sermon on the Mount	5—7	Kingdom ethics	7:28
2. Missionary Discourse	10	Apostolic mission	11:1
3. Parables Discourse	13	Kingdom mysteries	13:53
4. Community Discourse	18	Church relationships	19:1
5. Olivet Discourse	24—25	End times	26:1

Matthew structures his Gospel around these five blocks, a literary design many scholars have compared to the five books of Moses. Whether or not the Pentateuchal parallel is intentional, the placement of the Sermon on the Mount as the first discourse is not accidental. It establishes the ethical foundation for everything that follows. To read Matthew’s Gospel without taking the Sermon as programmatic is to remove the keystone from the arch.

The Audience Question: Matthew 5:1—2

“And seeing the multitudes, he went up into a mountain: and when he was set, his disciples came unto him: And he opened his mouth, and taught them.” --- Matthew 5:1—2 (KJV)

The audience question is the first interpretive fork. Who is “them”?

The grammatical evidence: The subject of “came unto him” is “his disciples” (hoi mathētai autou). The pronoun “them” (autous) in verse 2 refers most naturally to the disciples --- they are the nearest antecedent. On a plain grammatical reading, Jesus sits down (the posture of a rabbi teaching with authority), his disciples approach, and he teaches them.

But the conclusion complicates this:

“And it came to pass, when Jesus had ended these sayings, the people were astonished at his doctrine: For he taught them as one having authority, and not as the scribes.” --- Matthew 7:28—29 (KJV)

The word rendered “the people” is hoi ochloi --- “the crowds.” They were listening. They were astonished. Matthew does not say the crowds arrived at the end; he says they reacted to the teaching, implying they heard some or all of it.

Three readings of the audience:

Disciples only: Jesus addressed the Sermon exclusively to his committed followers. The crowds overheard but were not the intended recipients. On this reading, the Sermon is instruction for disciples --- for those who have already committed to follow Jesus --- and its demands (turn the other cheek, go the second mile, love your enemies) are comprehensible only within that commitment. This reading supports the view that the Sermon is for believers.
Crowds primarily: The Sermon is a public proclamation of kingdom ethics to Israel broadly. The disciples were present as the inner circle, but the teaching was directed at the whole nation. This reading supports the dispensational view that the Sermon addresses Israel, not the church specifically.
Concentric audience: Jesus teaches the disciples in the foreground while the crowds listen from the periphery. The teaching has both an inner meaning (for committed followers) and an outer witness (showing the crowds what the kingdom looks like). This is the most common scholarly reading and accommodates both the grammatical evidence (disciples addressed) and the narrative evidence (crowds listening and responding).

The text does not settle this question definitively. What it does establish is that the Sermon is delivered at minimum to disciples --- and the question of whether “disciples” in Matthew means “the Twelve,” “all followers of Jesus,” or “Israel awaiting the kingdom” is itself part of the debate.

The Hinge Passage: Matthew 5:17—20

This is the most contested passage in the entire Sermon for the question at hand. Every position must account for it.

“Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.” --- Matthew 5:17—20 (KJV)

Translation Comparison: Matthew 5:17—20

Translation	v. 17 “fulfil”	v. 18 “till all be fulfilled”	v. 20 “exceed”
KJV	”to fulfil"	"till all be fulfilled"	"shall exceed”
ESV	”to fulfill them"	"until all is accomplished"	"exceeds”
NASB	”to fulfill"	"until all is accomplished"	"surpasses”
LSB	”to fulfill"	"until all is accomplished"	"surpasses”
NIV	”to fulfill them"	"until everything is accomplished"	"surpasses”

Observation: The ESV and NIV add “them” after “fulfil,” making the object of fulfillment explicit (the law and the prophets). The NASB, LSB, and NIV render genētai (“be fulfilled” / “be accomplished”) differently from plēroō (“fulfil”) in verse 17 --- and rightly so, as they are different Greek words. The KJV’s “till all be fulfilled” uses the same English word as “fulfil” in v. 17, potentially obscuring the fact that the Greek vocabulary shifts.

Key Word: πληρόω (plēroō, G4137) --- “Fulfil”

Form in Matt 5:17: πληρῶσαι --- aorist active infinitive.

Root: From plērēs (“full”). The basic meaning is “to make full, to fill up, to bring to completion.”

BDAG (p. 828—829): “(1) to make full, fill (a space); (2) to complete a period of time, fulfill; (3) to bring to completion that which was already begun, complete, finish; (4) to bring to a designed end, fulfill (prophecy, promise, law).”

The critical question: what does Jesus mean by “fulfil the law”? The word plēroō has a wide semantic range, and the meaning here is sharply debated:

Reading 1 --- Prophetic fulfillment: Jesus “fulfils” the law and prophets in the sense that they prophesied about him and he is the one they pointed to. This is Matthew’s characteristic use of plēroō throughout the Gospel: “that it might be fulfilled which was spoken by the prophet” (1:22; 2:15, 17, 23; 4:14; 8:17; 12:17; 13:35; 21:4; 27:9). On this reading, Jesus does not abolish the law but brings it to its intended culmination in himself. Some dispensationalists use this reading to argue that Jesus fulfilled the law in toto and that Christians are therefore under the “law of Christ” (Gal 6:2), not the Mosaic code --- including the Sermon’s intensified demands.

Reading 2 --- Ethical completion: Jesus “fulfils” the law by revealing its deepest meaning and bringing it to its full expression. The six antitheses that follow (“ye have heard that it was said… but I say unto you”) are not abolitions of the Mosaic commands but intensifications and completions of them. Murder is extended to anger; adultery to lust; divorce is restricted; oaths are replaced by simple truth-telling; retaliation is replaced by non-resistance; love of neighbor is extended to love of enemies. On this reading, the Sermon represents the law in its fullest form --- and this full form is binding on all who follow Jesus.

Reading 3 --- Both: Jesus fulfils the law both by being the one it pointed to (prophetic fulfillment) and by revealing its complete ethical demand. These are not mutually exclusive.

The word plēroō itself does not resolve the debate. Matthew’s habitual use of the word throughout the Gospel (prophetic fulfillment) supports Reading 1 strongly, but the immediate context (six antitheses that intensify rather than abolish the law) supports Reading 2 with equal force.

”Till heaven and earth pass” (v. 18): Duration of the Law

“For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.” --- Matthew 5:18 (KJV)

This verse contains two temporal clauses:

“Till heaven and earth pass” (heōs an parelthē ho ouranos kai hē gē) --- this sets the outer boundary. As long as the physical universe endures, the law endures.
“Till all be fulfilled” (heōs an panta genētai) --- this sets a second condition. The word here is ginomai (G1096, “to become, to happen, to come to pass”), not plēroō from verse 17. Genētai is aorist subjunctive --- “until all things come to pass” or “until all is accomplished.”

The interpretive question: Are these two conditions sequential (the law endures until heaven and earth pass AND until all is accomplished), parallel (two ways of saying the same thing), or is the second clause a limiting condition (the law endures until heaven and earth pass --- unless all is accomplished first)?

If sequential or parallel: The law in its fullest form remains binding until the end of the physical creation. The Sermon, as part of Jesus’s authoritative teaching on the law, is therefore binding for all time.
If the second clause is a limiting condition: The law endures until “all is accomplished” --- and if “all” was accomplished at the cross and resurrection, then the law has been fulfilled and the Sermon’s demands belong to a different economy. This is the dispensational reading.

The grammar permits both. The doubled heōs an (“until”) with subjunctive is unusual, and commentators have debated its force since the patristic period.

”Exceed the righteousness of the scribes and Pharisees” (v. 20)

The word “exceed” is περισσεύω (perisseuō, G4052) --- “to be in abundance, to exceed, to overflow.” The verb does not mean “be different from” but “surpass” --- the disciples’ righteousness must be more than Pharisaic righteousness, not merely other than it. This is significant: Jesus does not dismiss the Pharisees’ concern with the law as misguided in principle; he says it does not go far enough.

The word δικαιοσύνη (dikaiosynē, G1343) --- “righteousness” --- appears five times in the Sermon (5:6, 5:10, 5:20, 6:1, 6:33) and is one of its governing terms. Its meaning in the Sermon is not primarily forensic (right legal standing before God, as in Paul’s usage in Romans) but behavioral: right living, conduct that conforms to God’s will. This is the meaning the word carries in the Psalms and Proverbs, and it is the meaning Matthew uses throughout his Gospel. The Sermon calls for a righteousness that is lived, not merely declared.

The Six Antitheses: Matthew 5:21—48

The antitheses form the structural core of the Sermon. Each follows the pattern: “Ye have heard that it was said (errethē) … but I say unto you (egō de legō hymin).” The formula is extraordinary. No rabbi in the Second Temple period claimed authority to reinterpret the Torah on his own authority. The phrase “but I say unto you” implies an authority equal to or greater than the law itself --- an authority the crowds recognized (“he taught them as one having authority, and not as the scribes,” 7:29).

Antithesis	OT Law	Jesus’s Teaching	Passage
1. Murder / Anger	”Thou shalt not kill”	Anger and contempt are murder of the heart	5:21—26
2. Adultery / Lust	”Thou shalt not commit adultery”	Lustful looking is adultery of the heart	5:27—30
3. Divorce	Moses permitted a certificate	Divorce (except for fornication) causes adultery	5:31—32
4. Oaths	”Thou shalt not forswear thyself”	Do not swear at all; let your yes be yes	5:33—37
5. Retaliation	”An eye for an eye”	Do not resist evil; turn the other cheek	5:38—42
6. Love / Hate	”Love thy neighbour”	Love your enemies; pray for persecutors	5:43—47

Two features of the antitheses are crucial for the question at hand:

First, Jesus does not abolish the old commands. He deepens them. Murder is wrong --- but so is the anger that leads to it. Adultery is wrong --- but so is the lust that produces it. This pattern of intensification rather than abrogation supports the “ethical completion” reading of plēroō in 5:17. Jesus fulfils the law by revealing the full scope of its demand.

Second, the commands are demanding to the point of seeming impossible. Turn the other cheek? Love your enemies? Be perfect as your Father in heaven is perfect? This is precisely the point at which the interpretive question becomes urgent. Are these literal commands for daily life (the Anabaptist reading)? Aspirational ideals that describe the direction of the Christian life without demanding sinless perfection (the mainstream evangelical reading)? Or commands for a future kingdom when the conditions for obedience will be different (the dispensational reading)?

”Be Ye Therefore Perfect”: Matthew 5:48

“Be ye therefore perfect, even as your Father which is in heaven is perfect.” --- Matthew 5:48 (KJV)

Translation Comparison: Matthew 5:48

Translation	Rendering	Notes
KJV	”Be ye therefore perfect”
ESV	”You therefore must be perfect”	Stronger imperative force
NASB	”Therefore you shall be perfect”	Future indicative reading
LSB	”Therefore you shall be perfect”	Same as NASB
NIV	”Be perfect, therefore”	Simple imperative

Key Word: τέλειος (teleios, G5046) --- “Perfect”

Form in Matt 5:48: τέλειοι --- nominative plural adjective, predicate of the imperative esesthe (“you shall be”).

Root: From telos (G5056), “end, goal, completion.” A thing is teleios when it has reached its telos --- its intended purpose. This is not primarily moral flawlessness (as “perfect” suggests in modern English) but functional wholeness: being complete, having reached maturity, fulfilling one’s design.

Usage elsewhere in the NT:

Reference	Form	Meaning in Context
Matt 19:21	τέλειος	”If thou wilt be perfect” --- complete devotion
1 Cor 2:6	τελείοις	Mature believers (vs. babes in Christ)
1 Cor 13:10	τὸ τέλειον	”The perfect” --- eschatological completeness
Eph 4:13	τέλειον	”A perfect man” --- corporate maturity in Christ
Phil 3:15	τέλειοι	”As many as be perfect” --- the mature
Col 1:28	τέλειον	”Present every man perfect in Christ”
James 1:4	τέλειοι	”Perfect and entire” --- completeness through patience
James 1:25	τέλειον	”The perfect law of liberty”
James 3:2	τέλειος	”A perfect man” --- one who controls the tongue

The context in Matt 5:48 is critical. The verse is the conclusion of the sixth antithesis --- love for enemies. The logic is: God sends rain on the just and the unjust alike (v. 45). Even tax collectors love those who love them (v. 46). You must do more --- love even those who hate you. Therefore be teleios as your heavenly Father is teleios. The perfection in view is not sinless performance across every moral category; it is specifically wholeness of love --- a love that does not discriminate between friend and enemy, because God’s love does not discriminate.

The Lukan parallel confirms this:

“Be ye therefore merciful, as your Father also is merciful.” --- Luke 6:36 (KJV)

Where Matthew has teleios (“perfect/complete”), Luke has οἰκτίρμων (oiktirmōn, G3629) --- “merciful, compassionate.” This is not a contradiction but a confirmation: the “perfection” in view is mercy, compassion, wholeness of love that extends even to enemies. The telos of the disciple is to love as the Father loves --- completely, without partiality.

This reading does not eliminate the force of the command. It sharpens it. The demand is not vague moral perfection but specific: love your enemies. That may be harder, not easier, than an abstract call to sinlessness.

The Doer and the Hearer: Matthew 7:21—27

“Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.” --- Matthew 7:21—23 (KJV)

“Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock. And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.” --- Matthew 7:24—27 (KJV)

This passage is the Sermon’s own internal commentary on how it is to be received. Three observations:

First, the phrase “these sayings of mine” (tous logous mou toutous) refers to the Sermon itself. The demonstrative toutous (“these”) points specifically to what Jesus has just finished teaching. The Sermon is not presented as optional wisdom or theoretical ethics. It is presented as the foundation on which a life must be built.

Second, the contrast is between hearing and doing. The wise man both hears and does; the fool hears but does not do. The verb ποιέω (poieō, G4160) --- “to do, to make, to perform” --- is straightforward. Jesus does not say “whosoever understands these sayings” or “whosoever appreciates these sayings” but “whosoever doeth them.” The emphasis on obedient action is unmistakable.

Third, the consequences are eschatological. The “rain, floods, and winds” language points to final judgment (cf. Ezek 13:10—16, where God tests false prophets’ work with storm and flood). The house that falls suffers a “great fall” (megalē hē ptōsis autēs). This is not a minor setback; it is catastrophic and final. Jesus is saying that failure to act on his teaching has eternal consequences.

The dispensational question: If the Sermon is not directly for the church age, then this passage presents a difficulty. Jesus says that hearing and not doing his words leads to destruction. Either the church is included in the audience obligated to obey, or these words must be assigned to a different dispensation entirely. The dispensational reading typically argues that the Sermon describes the ethic of the millennial kingdom and that the church will be raptured before these standards become operative. But the text itself provides no such temporal qualification --- it speaks to “whosoever” (pas hostis), without restriction.

The Crowd’s Reaction: Matthew 7:28—29

“And it came to pass, when Jesus had ended these sayings, the people were astonished at his doctrine: For he taught them as one having authority, and not as the scribes.” --- Matthew 7:28—29 (KJV)

The word “astonished” is ἐξεπλήσσοντο (exeplēssonto), imperfect passive of ekplēssō (G1605) --- literally “to be struck out of one’s senses.” The imperfect tense indicates continuous reaction: they kept being astonished. This was not a momentary impression but a sustained response.

The word “authority” is ἐξουσία (exousia, G1849) --- “authority, right, power.” The contrast is between Jesus and “the scribes” (hoi grammateis). Scribes derived their authority from tradition: they cited Rabbi Hillel, who cited Rabbi Shammai, who cited the oral tradition, which claimed to derive from Moses. Every teaching was grounded in prior human authority. Jesus grounds his teaching in himself: “but I say unto you.” This is an implicit claim to divine authority --- and the crowds felt the force of it.

The Great Commission: Matthew 28:18—20

“And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.” --- Matthew 28:18—20 (KJV)

This passage is the single most important text for determining the Sermon’s scope. The phrase “teaching them to observe all things whatsoever I have commanded you” (panta hosa eneteilamēn hymin) is comprehensive. The verb ἐντέλλομαι (entellomai, G1781) means “to command, to give orders.” The scope is panta (“all things”) qualified by hosa (“whatsoever, as many things as”). There is no restriction, no exception clause, no “all things except the Sermon on the Mount.”

The dispensational response: Some dispensationalists distinguish between the “kingdom gospel” Jesus preached during his earthly ministry (including the Sermon) and the “grace gospel” Paul later articulated. On this reading, the Great Commission instructs the disciples to teach what Jesus commanded them during the transitional period before the cross, but the church’s distinctive ethic comes from the Pauline epistles. However, this reading faces a significant textual problem: Matthew 28:20 does not say “some things” or “the things relevant to your dispensation.” It says “all things whatsoever I have commanded you.” The burden of proof falls on those who would limit this scope.

The word ἐντολή (entolē, G1785) --- “commandment” is worth noting in this context. While entolē does not appear in Matt 28:20 (the verb entellomai does), the noun form appears throughout the NT in critical contexts:

Matthew 22:36—40 --- “Which is the great commandment (entolē) in the law?” Jesus answers: love God, love neighbor. These are the Sermon’s governing principles.
John 13:34 --- “A new commandment (entolē) I give unto you, That ye love one another.” This is the Sermon’s ethic distilled.
John 14:15 --- “If ye love me, keep my commandments (entolas).” Jesus expects obedience to his commands as the fruit of love.
1 John 2:3—4 --- “And hereby we do know that we know him, if we keep his commandments (entolas). He that saith, I know him, and keepeth not his commandments, is a liar.”

The cumulative NT witness ties Jesus’s commands tightly to the ongoing life of the church. The Johannine literature especially makes obedience to Jesus’s commands a test of genuine faith --- not a dispensationally limited obligation.

The Sermon on the Plain: Luke 6:17—49

“And he came down with them, and stood in the plain, and the company of his disciples, and a great multitude of people out of all Judaea and Jerusalem, and from the sea coast of Tyre and Sidon, which came to hear him, and to be healed of their diseases.” --- Luke 6:17 (KJV)

Luke’s parallel is shorter than Matthew’s but shares substantial content: beatitudes (Luke 6:20—23), woes (6:24—26 --- absent from Matthew), love for enemies (6:27—36), judging (6:37—42), tree and fruit (6:43—45), and the two builders (6:46—49).

Is this the same sermon or a different one? The question has been debated since the early church. The key differences:

Feature	Matthew	Luke
Location	Mountain (5:1)	Plain (6:17)
Audience	Disciples primarily (5:1—2)	Disciples + great multitude (6:17)
Beatitudes	8 (spiritual emphasis: “poor in spirit”)	4 + 4 woes (material emphasis: “blessed be ye poor”)
Length	107 verses (Matt 5—7)	30 verses (Luke 6:20—49)
“Perfect” (5:48)	τέλειοι (“perfect/complete”)	οἰκτίρμονες (“merciful”) --- 6:36

Three views:

Same sermon, different reports: Matthew and Luke give condensed versions of a longer sermon. Matthew includes material Luke omits; Luke includes woes Matthew omits. The “mountain” and “plain” may refer to different parts of the same terrain (a level place on a mountainside).
Different sermons, overlapping content: Jesus was an itinerant preacher who repeated his teachings in different settings. A sermon given on a mountain to disciples was repeated on a plain to larger crowds.
Matthew’s composition: Matthew has gathered sayings from various occasions into a single literary discourse, as he does with the parables in Chapter 13. The Sermon on the Mount is a thematic collection, not a single historical event.

What this means for the question at hand: If the Sermon on the Plain is a separate event, then the Sermon’s ethical teaching was not a one-time address to a specific audience but a repeated pattern of instruction that Jesus considered central to his message. If Matthew compiled sayings from multiple occasions, the same conclusion follows: these teachings represent Jesus’s core ethical program. Either way, the content cannot be confined to a single audience or occasion.

The Lukan version is especially significant because Luke writes for a Gentile audience. If the Sermon’s teaching were exclusively for Israel, Luke’s inclusion of it in a Gospel directed to Theophilus (Luke 1:3) would be inexplicable.

James as Commentary on the Sermon

The Epistle of James is the NT document most densely packed with echoes of the Sermon on the Mount. Scholars have identified over twenty parallels --- and Porter’s tabulation documents forty-five parallel statements (BSac 162 [2005]: 347—52), concluding that “James was remarkably familiar with Jesus’ teachings” (BSac 162 [2005]: 482). James reads like pastoral application of the Sermon’s principles to church life.

“But be ye doers of the word, and not hearers only, deceiving your own selves. For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was. But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.” --- James 1:22—25 (KJV)

Compare with Matthew 7:24—27 (the wise and foolish builders): both passages contrast hearing with doing, and both declare that the one who does will stand while the one who merely hears will not. James’s “perfect law of liberty” (nomon teleion ton tēs eleutherias) echoes teleios from Matt 5:48 and resonates with the Sermon’s vision of a law that is fulfilled, not abolished.

“If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors. For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law. So speak ye, and so do, as they that shall be judged by the law of liberty.” --- James 2:8—12 (KJV)

James calls love of neighbor “the royal law” (nomon basilikon) --- the king’s law, the law of the kingdom. This is precisely the Sermon’s ethic: the law as interpreted and intensified by the King himself. James then applies it to the specific problem of favoritism in the assembly --- showing that the Sermon’s principles are operative in the church, not reserved for a future kingdom.

Selected parallels between James and the Sermon:

Sermon on the Mount	James
Blessed are the poor in spirit (Matt 5:3)	God hath chosen the poor of this world rich in faith (James 2:5)
Blessed are the merciful (Matt 5:7)	Mercy rejoiceth against judgment (James 2:13)
Blessed are the peacemakers (Matt 5:9)	The fruit of righteousness is sown in peace (James 3:18)
Swear not at all (Matt 5:34)	Above all things, my brethren, swear not (James 5:12)
Ask, and it shall be given you (Matt 7:7)	Ye have not because ye ask not (James 4:2)
Judge not (Matt 7:1)	Speak not evil one of another (James 4:11)
Lay not up treasures on earth (Matt 6:19)	Go to now, ye rich men (James 5:1)
Two builders: doer vs. hearer (Matt 7:24—27)	Be doers of the word, not hearers only (James 1:22)

The density of these parallels is remarkable. James does not quote the Sermon directly (he may have been working from oral tradition rather than Matthew’s text), but the thematic overlap is so extensive that many scholars regard James as the earliest commentary on the Sermon on the Mount --- applied to the life of the church.

Paul Echoing the Sermon: Romans 12:14—21

“Bless them which persecute you: bless, and curse not. Rejoice with them that do rejoice, and weep with them that weep. Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits. Recompense to no man evil for evil. Provide things honest in the sight of all men. If it be possible, as much as lieth in you, live peaceably with all men. Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. Be not overcome of evil, but overcome evil with good.” --- Romans 12:14—21 (KJV)

The Sermon’s echoes in this passage are unmistakable:

Sermon on the Mount	Romans 12
Love your enemies (Matt 5:44)	Bless them which persecute you (Rom 12:14)
Pray for them which persecute you (Matt 5:44)	Bless, and curse not (Rom 12:14)
Resist not evil (Matt 5:39)	Recompense to no man evil for evil (Rom 12:17)
Be ye therefore perfect (Matt 5:48)	Overcome evil with good (Rom 12:21)
Turn the other cheek (Matt 5:39)	Avenge not yourselves (Rom 12:19)

Paul does not attribute these instructions to the Sermon explicitly, but the content is so closely aligned that either Paul knew the Sermon tradition (orally or in written form) or both Paul and Jesus drew from the same Spirit-inspired ethical vision. In either case, the fact that Paul applies these principles to Gentile churches in Rome --- far removed from the Galilean hillside and the Jewish audiences of Jesus’s ministry --- is significant. Paul does not treat the Sermon’s ethics as limited to Israel or to a future dispensation. He applies them to the church age.

”The Law of Christ”: Galatians 5:14 and 6:2

“For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.” --- Galatians 5:14 (KJV)

“Bear ye one another’s burdens, and so fulfil the law of Christ.” --- Galatians 6:2 (KJV)

The phrase “the law of Christ” (ton nomon tou Christou) is uniquely Pauline and appears only here and in 1 Corinthians 9:21. What does it include?

The word πληρόω (plēroō, G4137) appears again --- “fulfil the law of Christ.” This is the same word Jesus used in Matt 5:17 (“I am not come to destroy, but to fulfil”). Paul says the entire law is “fulfilled” (peplērōtai, perfect passive) in the love command --- and that Christians are under “the law of Christ” which they fulfil by bearing one another’s burdens.

Does the “law of Christ” include the Sermon? The answer depends on how broadly one defines the phrase:

Narrow reading: “The law of Christ” refers specifically to the apostolic teaching as mediated through Paul and the other apostles. The Sermon is background but not directly normative.
Broad reading: “The law of Christ” encompasses everything Jesus commanded --- including the Sermon on the Mount, which is the most extensive collection of Jesus’s ethical teaching in the Gospels. The Great Commission (Matt 28:20 --- “all things whatsoever I have commanded you”) supports this reading.
Synthetic reading: “The law of Christ” is the Mosaic Law as interpreted and fulfilled by Christ. The Sermon is the primary text showing what this fulfilled law looks like in practice. Paul’s summary (“love thy neighbour as thyself”) is not a reduction of the Sermon but a distillation of its governing principle.

Paul’s own practice tilts toward the broad reading. In Romans 12—14, he applies Sermon-style ethics to church life. In 1 Corinthians 7:10, he explicitly appeals to the Lord’s command regarding divorce --- one of the Sermon’s topics (Matt 5:31—32). In 1 Thessalonians 5:15, he writes “see that none render evil for evil unto any man” --- a direct echo of Matt 5:38—42.

The Sermon’s Echoes Across the New Testament

The following table maps the Sermon’s major themes to their appearances elsewhere in the NT, demonstrating that the Sermon’s ethics were not confined to a single audience or dispensation but permeated the entire early church’s teaching:

Sermon Theme	NT Echo	Passage
Blessed are the persecuted (5:10—12)	Rejoice in suffering	1 Pet 4:13—14; Rom 5:3—5
Salt and light (5:13—16)	Light of the world	Phil 2:15; Eph 5:8—9
Fulfilling the law through love (5:17—20)	Love fulfils the law	Rom 13:8—10; Gal 5:14
Anger and reconciliation (5:21—26)	Put away wrath	Eph 4:26—27, 31—32; Col 3:8
Lust and purity of heart (5:27—30)	Flee fornication	1 Cor 6:18—20; 1 Thess 4:3—5
Marriage and divorce (5:31—32)	The Lord’s command	1 Cor 7:10—11
Honest speech, no oaths (5:33—37)	Swear not	James 5:12
Non-retaliation (5:38—42)	Overcome evil with good	Rom 12:17—21; 1 Pet 3:9
Love for enemies (5:43—48)	Bless persecutors	Rom 12:14; 1 Pet 2:23
Piety without hypocrisy (6:1—18)	Sincere faith	2 Tim 1:5; 1 Pet 1:22
Do not worry about provision (6:25—34)	Be anxious for nothing	Phil 4:6—7; 1 Pet 5:7
Do not judge (7:1—5)	Judge not before the time	1 Cor 4:5; Rom 14:4, 10—13
Golden Rule (7:12)	Mutual love	Rom 13:9; Gal 5:13—14
Known by fruits (7:15—20)	Fruit of the Spirit	Gal 5:22—23
Doers, not hearers (7:24—27)	Be doers of the word	James 1:22—25

The breadth of this table is itself an argument. The Sermon’s themes are not quarantined in the Gospels. They flow through Acts, the Pauline epistles, the General epistles, and Revelation. If the Sermon’s ethics were intended for Israel alone or for a future millennial kingdom, it is difficult to explain why virtually every NT writer independently applies them to the church.

The Kingdom of Heaven: Present or Future?

Key Phrase: βασιλεία τῶν οὐρανῶν (basileia tōn ouranōn) --- “Kingdom of Heaven”

This phrase appears 32 times in Matthew and nowhere else in the NT. The other Gospels use “kingdom of God” (basileia tou theou) in parallel passages, confirming that the two phrases are functionally equivalent. Matthew’s preference for “of heaven” reflects Jewish reverence that avoided speaking God’s name directly.

The dispensational question: Does “kingdom of heaven” refer to a future, literal, millennial kingdom that will be established when Christ returns to reign on earth? If so, the Sermon describes the ethics of that future kingdom, not the ethics of the church age.

The evidence within the Sermon:

Matt 5:3 --- “Blessed are the poor in spirit: for theirs is (estin, present tense) the kingdom of heaven.” Not “will be” but “is.” The kingdom belongs to the poor in spirit now.
Matt 5:10 --- “Blessed are they which are persecuted for righteousness’ sake: for theirs is (estin, present tense) the kingdom of heaven.” Again, present tense.
Matt 5:20 --- “Except your righteousness shall exceed (perisseuō, aorist subjunctive) the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.” The verb “enter” (eiserchomai) is aorist subjunctive --- the entry could be present or future.
Matt 6:10 --- “Thy kingdom come. Thy will be done in earth, as it is in heaven.” The prayer for the kingdom to “come” implies it has not yet fully arrived.
Matt 6:33 --- “But seek ye first the kingdom of God, and his righteousness.” The imperative “seek” (zēteite, present active) implies the kingdom is available to be sought now.

The picture is not either/or. The Sermon presents the kingdom as both already present (5:3, 5:10 --- “theirs is”) and not yet fully realized (6:10 --- “thy kingdom come”). This “already/not yet” tension is one of the best-established features of Jesus’s kingdom teaching across all four Gospels. The kingdom is inaugurated in Jesus’s ministry, present in the community of his followers, and awaiting consummation at his return.

If the kingdom is already present --- even if not yet fully realized --- then the ethics of the kingdom are already operative. The Sermon does not describe a future world; it describes how citizens of the present-and-coming kingdom are to live now, in the tension between inauguration and consummation.

Key Word Studies

μακάριος (makarios, G3107) --- “Blessed”

Form in the Beatitudes: μακάριοι --- nominative plural adjective.

Etymology: The word carries the sense of “happy, fortunate, blessed.” In classical Greek, it was used of the gods --- makarioi was the condition of the divine, free from toil and death. By the Hellenistic period, it had broadened to include human blessedness, particularly in the sense of divine favor.

LXX usage: Makarios translates the Hebrew אַשְׁרֵי (ashrei), the opening word of Psalm 1: “Blessed is the man that walketh not in the counsel of the ungodly.” The ashrei form is not a wish (“may you be blessed”) but a declaration (“in the state of blessedness is the one who…”). It describes a present reality, not a future hope.

In the Beatitudes: Jesus declares eight conditions of blessedness. Significantly, the first and eighth beatitudes share the same reward: “for theirs is the kingdom of heaven” (5:3, 5:10) --- creating an inclusio (a literary bracket) around the entire set. All eight beatitudes describe conditions that the world considers unfortunate (poverty of spirit, mourning, meekness, persecution) and declares them blessed. This is a reversal of worldly values that is characteristic of Jesus’s kingdom teaching.

δικαιοσύνη (dikaiosynē, G1343) --- “Righteousness”

Occurrences in the Sermon: Five times --- 5:6, 5:10, 5:20, 6:1, 6:33. This density is remarkable; the word governs the Sermon.

Semantic range:

Forensic (Pauline): Right standing before God, justification (Rom 1:17; 3:21—22; Phil 3:9)
Ethical (Matthean): Right conduct, behavior that conforms to God’s will (Matt 3:15; 5:6, 10, 20; 6:1, 33; 21:32)

In the Sermon, dikaiosynē consistently means right living, not forensic justification. Matt 5:20 makes this clear: the disciples’ righteousness must “exceed” (perisseuō) that of the scribes and Pharisees. The scribes’ righteousness was behavioral (meticulous law observance); Jesus does not say it was the wrong kind of righteousness but that it was insufficient in degree. The disciples need more right living, not a different category of standing.

Matt 6:1 makes the point explicitly: “Take heed that ye do not your righteousness (dikaiosynēn) before men, to be seen of them.” Here righteousness is something one does --- it is practiced, performed, enacted. The Sermon’s vision of righteousness is lived, not merely imputed.

This does not contradict Paul’s doctrine of justification by faith. The two uses of dikaiosynē operate in different registers: Paul addresses how one enters right standing with God (by faith, not works of the law); Jesus addresses how one lives within that relationship (with a righteousness that exceeds mere external compliance). They are complementary, not contradictory.

ἐντολή (entolē, G1785) --- “Commandment”

In the Sermon: Matt 5:19 --- “Whosoever therefore shall break one of these least commandments (entolōn), and shall teach men so, he shall be called the least in the kingdom of heaven.”

The “commandments” in view are disputed:

The Mosaic commandments: Jesus is speaking of the Torah’s commands, which he has just said he came to fulfil. The “least commandments” are the detailed provisions of the law.
Jesus’s own commandments: The Sermon itself constitutes Jesus’s new set of commands. The “least commandments” are the Sermon’s own instructions.
Both: Jesus is speaking of the Torah’s commands as interpreted and intensified by his own teaching. The two are not separable because Jesus has just declared he came to fulfil the law --- his teaching is the law in its fulfilled form.

Reading 3 is most consistent with the passage’s logic. Jesus says he fulfils the law (v. 17), that the law endures (v. 18), that breaking the least commandment has consequences (v. 19), and that the disciples’ righteousness must exceed Pharisaic standards (v. 20). Then he proceeds to show what this exceeded righteousness looks like: six antitheses that take the law deeper. The “commandments” of v. 19 are the law as Jesus interprets it --- which is what the rest of the Sermon provides.

The Dispensational Question from Scripture

The dispensational reading of the Sermon on the Mount, associated historically with Lewis Sperry Chafer, Charles Ryrie, and the Scofield Reference Bible, raises questions that deserve engagement with their strongest scriptural arguments.

Does Matthew 5:17—20 limit the Sermon to Israel?

The dispensational argument: Jesus was speaking to Jewish disciples under the Mosaic covenant, before the cross. The Sermon is “law” in the proper sense --- it intensifies the Mosaic code. The church, which did not yet exist (Matt 16:18, “I will build my church” --- future tense), is not under law but under grace (Rom 6:14). Therefore the Sermon addresses Israel, not the church.

The counter-evidence from Scripture: (1) Matt 28:20 commands the apostles to teach all nations to observe all things Jesus commanded. If the Sermon is not for the nations, this command is incoherent. (2) Paul, writing to Gentile churches, applies Sermon ethics throughout his letters (see the cross-reference table above). (3) James, writing to “the twelve tribes which are scattered abroad” (James 1:1) --- but widely understood as addressing Jewish Christians in the church --- applies Sermon teaching directly to church life. (4) The “already/not yet” character of the kingdom means the kingdom is operative in the church age, not postponed to a future millennium.

Does “kingdom of heaven” indicate a future millennial kingdom?

The dispensational argument: The “kingdom of heaven” is the literal messianic kingdom promised to Israel, which was offered and rejected during Jesus’s ministry. The Sermon describes the ethics of this offered-but-postponed kingdom. When the kingdom is finally established in the millennium, these ethics will be operative.

The counter-evidence from Scripture: (1) The present tense in Matt 5:3, 10 (“theirs is the kingdom”) indicates the kingdom is already in some sense present. (2) Matt 12:28 --- “But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you” --- ephthasen, aorist indicative, indicating the kingdom has arrived. (3) Col 1:13 --- “Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son” --- past tense; believers are already in the kingdom. (4) The Lord’s Prayer itself (Matt 6:10) expects the kingdom’s coming to affect the present: “Thy will be done in earth, as it is in heaven.”

Does the Sermon’s impossible ethic prove it is not for the church age?

The dispensational argument: The Sermon’s demands --- love your enemies, turn the other cheek, be perfect as the Father is perfect --- are impossible to fulfill in the present evil age. They presuppose the conditions of the millennial kingdom, where Satan is bound and Christ reigns visibly. Applying them literally now leads either to despair or to legalism.

The counter-evidence from Scripture: (1) Paul and Peter command the same things (Rom 12:14—21; 1 Pet 3:9) without suggesting they are impossible for the church. (2) The indwelling Holy Spirit, given at Pentecost, enables what the flesh cannot perform (Gal 5:16—25; Rom 8:3—4). (3) Jesus did not say “these commands will be possible someday”; he said “whosoever heareth these sayings of mine, and doeth them” (Matt 7:24) --- present tense, no temporal qualifier. (4) The Anabaptist tradition and communities like the Hutterites, Amish, and Bruderhof have practiced Sermon ethics for centuries, demonstrating that while costly, they are not impossible.

What Is Clear

The Sermon on the Mount (Matthew 5—7) is the first and most programmatic of Jesus’s five major discourses in Matthew. It establishes the ethical foundation for the entire Gospel.
Jesus explicitly states he has come not to destroy the law but to fulfil it (5:17), and that the law endures “till heaven and earth pass” (5:18).
The six antitheses (5:21—48) intensify rather than abolish the Mosaic commands, revealing their full scope: the law addresses the heart, not merely external behavior.
The Sermon’s own conclusion (7:24—27) insists on obedience: the one who hears and does not do faces catastrophic judgment.
The Great Commission (Matt 28:18—20) commands the apostles to teach all nations to observe “all things whatsoever I have commanded you” --- a scope that naturally includes the Sermon.
The rest of the New Testament extensively echoes the Sermon’s ethics. James, Paul, Peter, and John all apply Sermon-derived teaching to church life without dispensational qualification.
The word teleios (“perfect”) in Matt 5:48, read in context, refers specifically to wholeness of love --- loving without discrimination, as the Father does. The Lukan parallel confirms this: “Be ye therefore merciful, as your Father also is merciful” (Luke 6:36).
The “kingdom of heaven” in the Sermon is presented as both already present (5:3, 5:10 --- “theirs is”) and not yet consummated (6:10 --- “thy kingdom come”). The Sermon addresses life in this already/not-yet tension.

What Is Debated

Whether plēroō (“fulfil”) in Matt 5:17 means (a) prophetic fulfillment (Jesus is the one the law pointed to), (b) ethical completion (Jesus reveals the law’s full scope), or (c) both. The word’s semantic range accommodates all three, and the immediate context supports at least (b) and possibly (c).
Whether “till all be fulfilled” (5:18) limits the law’s duration to the cross/resurrection (at which point “all was accomplished”) or extends it to the end of the physical universe (“till heaven and earth pass”). The relationship between the two temporal clauses in 5:18 is grammatically ambiguous.
Whether the Sermon’s demands are literal commands, aspirational ideals, or kingdom-age ethics. Anabaptists take them as literal and binding; mainstream evangelicals treat them as directional (describing the trajectory of the Christian life without demanding sinless perfection); dispensationalists assign them primarily to a future kingdom. The text itself offers no explicit hermeneutical instruction on this point.
Whether the “kingdom of heaven” is (a) the present spiritual reign of Christ, (b) the future millennial kingdom, or (c) both already and not yet. The present-tense verbs in 5:3 and 5:10 support (a) or (c); the petition “thy kingdom come” in 6:10 supports (b) or the “not yet” dimension of (c).
Whether Luke’s Sermon on the Plain is the same event as Matthew’s Sermon on the Mount and, if different, what the implications are for the Sermon’s audience and scope. Both Gospels treat the teaching as central to Jesus’s message.
Whether “the law of Christ” (Gal 6:2) explicitly includes the Sermon on the Mount. Paul does not define the phrase, but his repeated application of Sermon-style ethics to church life suggests a connection that is at minimum strong and arguably definitive.
Whether the Sermon’s impossible-seeming demands (love your enemies, be perfect as the Father is perfect, turn the other cheek) prove it is not for the current age or whether they presuppose the enabling power of the Holy Spirit. Both positions have NT support (the dispensational appeal to the distinction between law and grace; the continuationist appeal to the Spirit’s empowerment in Galatians 5 and Romans 8).

Summary

The textual evidence does not permit the Sermon on the Mount to be easily quarantined from the life of the church. The Sermon itself claims binding authority (“whosoever heareth these sayings of mine, and doeth them”). The Great Commission extends that authority to all nations and all ages. The rest of the New Testament --- James, Paul, Peter, John --- independently applies Sermon ethics to church life without any suggestion that these teachings belong to a different dispensation.

At the same time, the dispensational reading raises genuine questions that cannot be dismissed. The Sermon is addressed to Jewish disciples before the cross. The phrase “kingdom of heaven” does have eschatological dimensions. The Sermon’s demands are extraordinarily high --- so high that serious interpreters have always asked whether they can be the ethic of a fallen world or must await a redeemed one.

What the text makes unmistakably clear is this: Jesus taught the Sermon with the expectation that it would be obeyed. He did not present it as theoretical, aspirational, or dispensationally limited. He presented it as the foundation on which lives are built or destroyed (7:24—27). He taught it with an authority the crowds had never encountered (7:28—29). And he commissioned his apostles to teach all nations to observe everything he had commanded (28:20).

How the church has received this teaching --- from the Didache to the Anabaptists to modern dispensationalism --- and what Jesus himself demonstrated about its practice, are the subjects of the chapters that follow.

Next: Chapter 2 examines what Jesus himself demonstrated about the Sermon’s ethics --- how he lived out his own teaching, and what his priorities reveal about the question at hand.
