How Jesus Christ Fulfills the Law: Matthew 5:17-19

Christ fulfilled or paid off your debt to the Law. It’s paid in full. He accomplishes this by fulfilling the holiness demand in the law and the fullest revelation of God’s character.

In fact, he has fulfilled, is fulfilling, and shall completely fulfill the entire Old Testament.

All you have to do is follow him as you live in the Spirit after Pentecost (Acts 2). But if people get confused about it, the moral law, which is everywhere in the New Testament, is still valid. So what areas of the law does Christ fulfill?

Introducing the passage

The three-year ministry of Jesus Christ, culminating in his death and resurrection and his establishment of his church, makes all the difference in the transition from the Old Testament or Covenant to the New Testament or Covenant. In those three short years he ushered in a new era of salvation, although the old era contained the seeds of the new.

The most salient and sometimes difficult statement on the relationship between Jesus and his disciples and the Old Covenant is found in Matthew 5:17-19, in the context of the famous Sermon on the Mount. The four verses read as follows in the New International Version (NIV):

17 Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. 19 Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. (Matt. 5:17-19)

This is a complex passage because, among other reasons, at first glance it seems that the Law and Prophets (a New Testament way of saying the entire Scriptures; cf. Matt. 22:40; Luke 16:16) is still in full force until heaven and earth pass away. But the Old Covenant prescribes animal sacrifices, whereas Christians no longer perform them in order to pay for their sins. What is happening?

The Old Covenant is to the New Covenant what promise is to fulfillment. How did, does, and shall Jesus Christ fulfill the promises of the Old Covenant?

That story is complex. Christians are commanded to read the Old Testament and are allowed to benefit from it, but they do not take everything in it as final. Christians honor the Old Testament as the Word of God, just as Jesus did. But they read it, ultimately, through the vision of Jesus and the Spirit-inspired authors of the New Testament books and epistles.

Not everything as final? What parts still apply to them today, if any?

It is imperative to analyze a sacred text in its historical and textual contexts.

Verse by verse exegesis

Exegesis means leading out the truth of a passage. Matt. 5:17-19 is best analyzed verse by verse, sometimes clause by clause, and even word by word.

17 Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.

Antinomianism means to oppose law that regulates life. Jesus was not an antinomian. He was not against the law. As a devout Jew he honored it. But he must make the change from the Old Covenant to the New Covenant, from the law of Moses to the “law” of Christ. That is his mission.

The following three clauses and words in verse 17 are important for understanding this verse.

I have come: These words make the entire four verses Christ-centered. Indeed, this fits into the four Gospels. He is the one who fulfills the Old Testament by his sinless life. He is the one to fulfill its prophecies about his first coming. He fulfills it by his death and resurrection. He is the one to fulfill it by the establishment of his worldwide church. And he will fulfill it at his Second Coming.

Abolish: this translation is appropriate for a literary context, but it does not express the full meaning. The Greek word is kataluô, whose primary meaning is “destroy,” “demolish,” “dismantle” as in a house or temple, or “detach a stone from a building.” This is revealing of Matt. 5:17. Jesus does not destroy the law as a whole, but he does fulfill passages, such as animal sacrifices.

Maybe an analogy or illustration will help. Let’s suppose that an Old House represents the Old Covenant Scriptures, and a New House represents the New Covenant and Christ’s ministry and the New Testament. Christ does not demolish the Old House, but he keeps it intact. Instead, he builds his New House next to it or even connected to it, sharing the same divine foundation. Christians live in the New House, which is grander and taller and has newer furnishings. They are allowed to visit the Old House. That is, they may read Psalms, Proverbs, the prophets, histories, the Torah, and so on. They may be edified by the stories and promises found there, just as a visitor to the grand Old House can learn a lot from and enjoy the old furnishings and old-style architecture. But the Old House does not hold them in. They live in the New House.

Fulfill: This word means to complete a promise or a prophecy or a prediction. The Old Covenant is to the New Covenant what promise is to fulfillment. The Old Testament contained types and shadows, which find their full meaning and substance in Christ. Jesus is the fulfillment in his very being and in his coming to earth.

What are some of the areas or themes in the Old Testament that Christ fulfills? The following five major ones represent others.

(1) In the Torah (first five books of the Bible), the three traditional divisions are fulfilled: the moral, judicial, and ceremonial.

There may be more divisions, and these three can perhaps be further subdivided, but let’s keep things simple for this post. I won’t cover moral law because much (not all) of it has been brought forward to the New Covenant Scriptures.

Do Christians Have to ‘Keep’ the Ten Commandments?

First, Jesus fulfills the ceremonial or ritual aspect of the Torah.

Besides the atonement or blood sacrifices, Christians are permitted to eat whatever foods their conscience allows them (Mark 7:14-19). If they voluntarily keep away from traditionally unclean animals like swine, then they are free to do this. But this is not a requirement from Christ or the New Testament authors. In Christ, all foods are ritually clean. After he ascended into heaven, he sent a vision to Peter about animals becoming clean. A voice from heaven said to the lead Apostle: “Do not call anything impure what God has made clean” (Acts 10:15).

Second, Jesus fulfills the judicial aspect of the Torah.

His death on the cross takes away the severe penalty of death for sins like homosexuality and cursing parents. His death takes their place because divine wrath for human sins was poured on him on the cross. Criminals like thieves and murderers should be punished, because of the principles of justice behind the particular rules. But they can have their sins forgiven while they suffer the just consequences of their crimes. Jesus and the New Testament authors never rescinded justice.

(2) Christ fulfills a geographical promise.

God gave the land of Canaan to Abraham, the father of the ancient Hebrews (Genesis 17:8). That promise was repeated to Moses (Exodus 6:4). Joshua, the successor of Moses, spent most of his later life purging the land of debased and degraded Canaanites. However, Jesus said in Matt. 28:18-20 that he sends his disciples to all nations. He raises his vision higher than a small geographical region, up to the entire world. Now Christians are called to wage spiritual warfare (not military warfare) by preaching the gospel to everyone. The calling of the first Joshua after Moses is spiritually fulfilled by the later Joshua—Jesus’ name in Hebrew is Joshua.

(3) In the Old Covenant, God gave commands on how to build a mobile tabernacle (Exodus 25-27).

Then he gave special permission to Solomon to build a permanent temple (1 Kings 5:1-6:38 and 7:13-8:66). However, Jesus fulfills this earthly temple in his own person and in his church. Jesus says to the Pharisees, referring to himself: “I tell you that one greater than the temple is here” (Matt. 12:6). Jesus said this in the context of keeping the law and sacrificing in the temple. He now fulfills the temple sacrifices and becomes a living temple through his new people of God: his church (1 Corinthians 3:16 and 1 Peter 2:4-8). His church is found around the world now, so his living temple is worldwide.

(4) Christ fulfills prophecies that predicted his first coming.

This theme relates to a major part of the Old Testament in Matt. 5:17—the “Prophets.” They promised a new era of salvation, and Jesus fulfills that promise. The primary example among many, many others is found in Isaiah 53, which describes the suffering Servant-Messiah. Verse 5 says: “But he was pierced for our iniquities; the punishment that brought us peace was upon him, and by his wounds we are healed.” This is a perfect description of Jesus’ death on the cross, since he was wounded and pierced. His death brings us peace from God because it atones or pays for our sins. He fulfills every prophecy that predicted his first coming.

(5) Besides Christ’s first coming, some prophecies have been partially fulfilled and are still in the process of being fulfilled.

They will be completely fulfilled in the future at his Second Coming. Joel 2:28-32 is a good example. God promises his people restoration after divine judgment. He promises them that he will pour out his Spirit on them to restore and bless them:

2:28 I will pour out my Spirit on all people. Your sons and your daughters will prophesy, and your old men will dream dreams, your young men will see visions. 29 Even on my servants, both men and women, I will pour out my Spirit in those days.

In the New Testament the Apostle Peter applies this prophecy to the church that Jesus established. It is the Day of Pentecost, a celebratory feast (see Exodus 23:16). God sends his Holy Spirit like a mighty wind and fills everyone who was praying in an upper room. Acts 2:1-4 describes the blessed scene:

2:1 When the day of Pentecost came, they were all together in one place. 2 Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. 3 They saw what seemed to be tongues of fire that separated and came to rest on each of them. 4 All of them were filled with the Holy Spirit and began to speak in other tongues, as the Spirit gave them utterance. (Acts 2:1-4)

This is a holy moment. Joel promised that God would send his Sprit to his people, and Jesus promised that he would also do this (John 16:5-16). That promise was fulfilled in Acts 2:1-4. Peter understands this, so he applies the prophecy in Joel to this holy moment (Acts 2:16-21). And it is still being fulfilled. God continues to send his Spirit into people who ask him.

But there is another part of the prophecy in Joel that awaits fulfillment. God through Joel describes what will happen in the Last Days. God will show wonders in the heavens and on earth—blood and fire and billows of smoke. Then the sun will be turned to darkness and the moon to blood (Joel 2:30-31). But the good news follows: “And everyone who calls on the name of the Lord shall be saved” (v. 32). Jesus repeats this prophecy as valid and still waiting fulfillment (Matt. 24:29; cf. Isaiah 27:13; 34:4; Ezekiel 32:7). It will happen just before he returns in his Second Coming.

To sum up, Jesus has fulfilled, is fulfilling, and shall completely fulfill the entire Old Testament. The Old Covenant is to the New what promise is to fulfillment. He has ushered in the new era of salvation in the flow of God’s plan of salvation begun in the Old Testament. All the promises of God are absorbed in Christ’s life and being. He becomes the fulfillment of the Old Testament without destroying it.

The Old Testament remains until heaven and earth pass away and “until everything is accomplished.”

But how does this relate to my life personally? Christ’s fulfilling the law can be illustrated like this: when we owe a debt, but someone pays it off for us, then we should stop paying the debt. We owed a debt to the law, but Christ fulfilled or paid off our debt. The only way he asked us to pay him back (as if we could) is to follow him now. We are now followers of Christ, not the Law of Moses.

18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.

This verse demonstrates that the Old Testament has an expiration date that has not yet arrived. The two “until” clauses offer us hints on when that date will come.

The first “until” clause says: “until heaven and earth disappear.” There is nothing complicated here. God’s Word remains until the physical universe is wrapped up. Peter the Apostle, under the inspiration of the Spirit, agrees (2 Peter 3:10):

3:10 But the Day of the Lord will come like a thief in the night [unpredicted]. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything in it will be laid bare. (2 Peter 3:10; see also Hebrews 12:27)

However, it should be recalled that the very words of Jesus Christ will remain even after the universe disappears: “Heaven and earth will pass away, but my words will never pass away” (Matt. 24:35). Jesus uses the same phrase to express the complete reliability and firmness of his prediction–his prediction is firmer than the heavens and earth. This means that Jesus Christ supercedes the Old Testament, fulfilling it back then, now, and in the future–the resurrection.

The phrase is merely a conventional way of saying “never” (Jer. 31:35-36; 33:20-21, 25-26; Job 14:12; positively: Ps. 72:5, 7, 17). Heaven and earth not passing away is more of a statement of inviolability than a time marker (France, The Gospel of Matthew: New International Commentary on the New Testament, [Eerdmans 2007], pp. 185-86).

We can see this time marker in Matt. 11:13, which says that all of the law and prophets have prophesied until John the Baptist. He kicked off the fulfillment process and Jesus will complete it. Therefore, returning to 5:18, let’s not over-interpret the phrase “until heaven and earth” as if the law will never be or can never be fulfilled. It can and will be fulfilled when everything is accomplished. Jesus will do this at his resurrection and ascension. This second “until” is the time marker in Matthew’s Gospel, not the first “until” about heaven and earth being permanent.

Here is Luke’s testimony about Jesus fulfilling the law and prophets. Jesus is speaking after his resurrection:

44 Then he said to them, “These were my words which I have spoken to you while I was with you, because it was destined that all the things written in the law of Moses and the Prophets and Psalms about me be fulfilled. 45 Then he opened their minds to understand the Scriptures. 46 And he said to them that in this way it was written that Christ must suffer and rise from the dead on the third day, 47 and in his name repentance for the forgiveness of sins would be proclaimed to all nations, beginning from Jerusalem. (Luke 24:44-47, my translation)

In v. 45, he opened their minds to understand the Scriptures, and v. 46 indicates that he was to suffer and rise from the dead. The law and prophets have been fulfilled in him now because of the resurrection.

The next “until” clause says: “until everything is accomplished.” Matthew is writing the life of Christ in narrative or story form. Matthew quotes many Old Testament references to Christ throughout his narrative. We should therefore understand the word “everything” in that light. Jesus Christ fulfills the Hebrew Bible at his birth. He fulfills it during his life and ministry. He fulfills it especially in his death on the cross and his resurrection because these two events ratify and confirm all else that precedes them. Next, he fulfills the promises in the Hebrew Bible in the new age of salvation, through his church and through historical events (though this last category is harder to detect). He will fulfill everything in the Hebrew Bible at his Second Coming. Finally, the Old Testament will become completely null and void only when God himself will wrap up the universe like a mantle of clothing, tossing it aside.

This is what “until heaven and earth disappear” and “until everything is accomplished” mean. God’s Old Covenant Word—every smallest letter and stroke of the pen—will last as long as the universe does.

19 Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven.

This verse is divided into two main clauses: (1) those who break the commandments and teach others to do so; and (2) those who practice the commandments and teach others to do the same.

The first clause is easier to understand. The analogy of the Two Houses may clarify matters. When Christians go back to the Old House (the Old Testament), they are not allowed to break items in the Old House. They must not pick up an old dish (a command) and smash it on the floor. Instead, they should leave things as they found them when they return to the New House (New Testament). Leaving things alone is not the same as breaking them. Above all, if Christians become teachers, they should not teach others to break items in the Old House. Rather, they teach their fellow Christians to respect and honor the Old House as a whole, and the items found in it.

The second clause in verse 19 is a little more difficult to understand, but reading this verse in the context of the two preceding verses and of the entire Gospel of Matthew will make things clear.

In verses 17 and 18 (analyzed in the two previous sections), we learned that Jesus has fulfilled, is fulfilling, and shall completely fulfill the promises in the Old Testament. Therefore, he must be our interpretive guide as we read, practice, and teach the commandments. To use the Old and New Houses again, when we enter the Old House, we look at it through the vision of Jesus and through his fulfillment. He is our authoritative tour guide, so to speak. We obey the commands as they have been conditioned by his new era of salvation.

This conditioning is the theme of the entire sweep of Matthew’s Gospel. As noted in the section “historical and literary contexts,” in verse 19, Jesus is speaking the Sermon on the Mount to disciples still living under the Old Covenant. After the Sermon is over, he gradually reveals a new direction. He is making a transition from the Old to the New, building the New House without destroying the Old One. When the Gospel culminates in the last chapter, Jesus instructs his disciples to teach all nations everything he commands (Matt. 28:20). As the “fulfiller” of the promises of God, he must take priority.

However, does this mean that the entire Old Testament has been canceled, abrogated, annulled, demolished, dismantled, or destroyed (words that translate the Greek word kataluô in v. 17)? Not “until heaven and earth disappear” and not “until everything is accomplished.” The Old House is still standing without one piece missing or taken from it. All the items and furnishings are still in it. Rather, Jesus lifts our vision to the New House and calls us into it. Every commandment that is contained in the Old Testament can still be read, taught, and practiced for edification and blessing. But they must now be read through the fulfillment process and through the person and work of Jesus Christ.

For example, when Christians read about animal sacrifices in Leviticus, they focus on Christ’s sacrifice, realizing that the old sacrificial system pointed to him. They “practice” it by offering a sacrifice of praise to God: “Through Jesus, therefore, let us continually offer to God a sacrifice of praise” (Hebrews 13:15). This Spirit-inspired verse was written in the context of Christ’s sacrifice of his blood on the cross outside the city of Jerusalem. Also, Paul says we should offer our bodies as living sacrifices: “holy and pleasing to God—this is your spiritual act of worship” (Romans 12:1). Jesus Christ inspires all believers to lift their vision beyond the literal sacrifice of animals and look to him, the literal and once-and-for-all and unique sacrifice for all times. Then they “practice” their own spiritual sacrifice. Therefore, the Old Testament has been fulfilled in this area.

Thus, it always wise to let surrounding verses interpret a target verse. In this case, verses 17 and 18 interpret the target verse 19. And it is always wise to interpret a target verse in light of the entire text where it is found: the Gospel of Matthew.

Jesus conditions and interprets the old commandments that we teach and practice. We look at them through his vision.

How does this post help me grow in my walk with God?

If Christians want to practice the commandments in the Old Testament, they should learn from Christ’s wisdom revealed in Matt. 22:24-40. As noted in the analysis of Matt. 5:17, the Pharisees wanted to trap Jesus with words, so one of them, an expert in the law, asked him which commandment was the greatest.

22:37 Jesus replied: “Love the Lord your God with all your heart and with all your soul and with all your mind.” 38 This is the first and greatest commandment. 39 And the second is like it: “Love your neighbor as yourself.” 40 All the Law and the Prophets hang on these two commandments. (Matt. 22:37-40)

Jesus boils down all the commandments in the Old Testament to these two. They are the best way to obey all of them. Jesus’ followers should live a life of divine love through the power of the Holy Spirit in Jesus’ name.

Paul is in agreement with his Lord and Savior, using the key words “fulfilled” and “fulfillment” (Romans 13:8-10):

13:8 [F]or he who loves his fellowman has fulfilled the law. 9 The commandments, “Do not commit adultery,” “Do not murder,” “Do not steal,” “Do not covet,” and whatever other commandment there may be, are summed up in this one rule: “Love your neighbor as yourself. 10 Love does no harm to the neighbor. Therefore, love is the fulfillment of the law. (Rom. 13:8-10)

Only the life and love of Jesus Christ that he sends into our hearts through the Holy Spirit can enable us to walk in divine love. Our love for God cannot be self-initiated. God draws us to love him by his Spirit. This is the first great commandment. Only as we love him, we love others. That is the second greatest commandment. As for righteousness coming from keeping the two greatest commandments, only his righteousness that he offers us freely after his death on the cross and resurrection can save us. Our own righteousness cannot.

We must trust in Jesus Christ and receive the Holy Spirit and his righteousness in his name.

We Christians honor and revere the Old Testament, but we interpret it through Jesus Christ and the new era of salvation and fulfillment that he ushered in on the day he was born.

But Christ paid off your debt to the Law. It’s paid in full. Don’t send in any more payments. Just live life in the Spirit. But if you get confused, then the moral law still applies, especially the moral law that was transferred from the Old into the New.
