Matthew 5:17-20 Meaning
Jesus says he did not come to abolish the Law or the Prophets but to fulfill them, and he warns that his followers must live with a righteousness greater than the scribes and Pharisees. Early Christian writers like Irenaeus, Tertullian, Origen, Justin Martyr, and Cyprian used this passage to defend the lasting truth of Scripture. They read it as a call to faithful obedience, not a permission to ignore God’s commands. That makes this passage important for understanding both Jesus’ teaching and how the early church handled the Old Testament.

What does Matthew 5:17-20 mean?
Matthew 5:17-20 means Jesus did not come to cancel the Law and the Prophets, but to bring them to their intended goal. He says not even the smallest part of the law will fail until all is fulfilled, and he warns that his followers must have a righteousness greater than that of the scribes and Pharisees. Early Christian writers like Irenaeus, Tertullian, Origen, Justin Martyr, and Cyprian used this passage to argue that Christ fulfills Scripture without making it worthless.
They also used it to press for real obedience, not just outward rule-keeping. Many more early Christian quotations, Bible passages, and source links are gathered below so you can study the evidence for yourself.
Passage context
This saying comes near the start of the Sermon on the Mount in Matthew 5. Jesus has just begun teaching about the kingdom of heaven and the kind of life his disciples should live. Right after this, he gives examples that show how his teaching goes deeper than outward behavior.
Why early Christian sources matter
Early Christian writers help show how the first generations after the apostles understood this verse. They often used it against people who said Jesus had thrown out the law or that the old Scriptures no longer mattered. Their quotes show a steady reading: Christ fulfills the law, and his followers must live in a way that matches that fulfillment.
Common interpretation points
- The strongest early Christian theme is fulfillment, not abolition.
- Matthew 5:20 is often linked with Matthew 23:23 and Matthew 22:40, which help explain that Jesus cared about the law’s true purpose.
- Some later writers apply the passage to debates about heresy, church order, or ritual practice, so those uses are supportive but not the main meaning.
Evidence-Based Summary
Matthew 5:17-20 teaches that Jesus did not cancel the Law and the Prophets but brought them to their intended goal, and he warned that even the smallest command matters. Early Christian writers such as Irenaeus, Tertullian, Origen, Justin Martyr, Cyprian, and the Apostolic Constitutions repeatedly read the passage this way. They used it to defend the lasting truth of Scripture, to reject claims that Christ erased the law, and to stress that real righteousness must go beyond outward rule-keeping.
The evidence is broad and consistent, though some later writers go beyond the passage into larger debates about the law’s place in the church.
Key Takeaways
- Jesus says the law is fulfilled in him, not thrown away.

...re deeply as signifying spiritual truths by bodily facts, touched the leper. In this way He did not destroy the law, but rather built it up, because He wanted it to be acknowledged more earnestly. Even though as man He might have been defiled, as God He could not be defiled, because He is incorruptible. Therefore the command was not meant for Him in the sense that He was bound to obey the law and not touch the unclean person, since contact with the unclean could not defile Him. So I teach that this immunity is consistent with my Christ, especially when I show that it is not consistent with yours. Now if He touched the leper as an enemy of the law, disregarding the law’s command out of contempt for defilement, then how could he be defiled if he did not have a body that could be defiled? A phantom cannot be defiled. Therefore, one who could not be defiled because he was a phantom would not have immunity from pollution by divine power, but by his empty unreality. Nor can he be regarded as having despised pollution if he had no real bodily capacity for it. In the same way, he cannot be regarded as having destroyed the law if he escaped defilement because of his phantom nature, and n

...spel in which our Lord Jesus Christ said about Himself, "I have not come to destroy the law, but to fulfill it." But the man insisted that He did not say this at all. He argued that when we see that Christ actually set aside that same law, we must pay attention above all else to what He actually did. Then he began to quote many passages from the law, and also many from the Gospel and from the Apostle Paul, which seem to contradict one another. He said all this with complete confidence, and without any hesitation or fear. So I truly believe that he has that serpent as his helper, the one who is always our enemy. He said that in the law God says, "I make the rich man and the poor man," while here in the Gospel Jesus called the poor blessed and added that no one could be His disciple unless he gave up all that he had. Again, he argued that Moses took silver and gold from the Egyptians when the people fled from Egypt, but Jesus gave the command that we should not desire anything that belongs to our neighbor. Then he said that Moses had provided in the law that an eye should be given for an eye, and a tooth for a tooth. But our Lord commanded us to offer the other cheek also to the o

...ishes in the world to come. From this, then, notice how He confirms the law, not destroying it, but fulfilling it. In this way, then, He redeemed them from that curse of the law which belongs to the present life. And from this has come the expression, "the curse of the law." This is the full explanation that needs to be given of that way of speaking. But again, why the law is called "the strength of sin," we will now explain briefly as best we can. Now it is written that "the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners." In those times, then, before Moses, there was no written law for transgressors. So Pharaoh, not knowing the strength of sin, sinned by oppressing the children of Israel with unjust burdens, and he despised the Godhead, not only himself, but also all who were with him. But, so that I do not explain it in a roundabout way, I will state the matter briefly like this. There were certain people of the Egyptian race mixed in with the people of Moses when that people was under his rule in the wilderness. And when Moses had gone up the mountain to receive the law, the impatient people, I do not mean those who

For by His coming, He Himself fulfilled all things and continues to fulfill in the Church the new covenant foretold by the law, onward to the completion of all things. Paul, His apostle, also says this in the Epistle to the Romans, "But now, without the law, the righteousness of God has been revealed, witnessed by the law and the prophets; for the just shall live by faith." The fact that the just shall live by faith had been previously announced by the prophets.

...hat He might deliver those who were subject to them from the wrath reserved for them, that He might fulfill the Law and the Prophets, and that He might remove or change those secondary bonds that were added to the rest of the law. That is why He called to us and said, "Come to me, all you that labor and are heavy laden, and I will give you rest." Matthew 11:28 Therefore, when you have read the Law, which agrees with the Gospel and the Prophets, read also the books of the Kings. Then you may learn which kings were righteous, how God made them prosper, and how the promise of eternal life remained with them from Him. But those kings who went astray from God quickly perished in their apostasy by the righteous judgment of God, and were deprived of His life, inheriting eternal punishment instead of rest. Therefore, by reading these books you will be greatly strengthened in the faith and built up in Christ, whose body and member you are. Moreover, when you go out in public and want to bathe, use the bath that is set apart for men, lest by uncovering your body in an improper way to women, or by seeing a sight improper for men, either you are ensnared, or you ensnare and attract to yours

... yourselves to the priests." Luke 17:14. For He nowhere has abolished the law, as Simon claims, but fulfilled it. For He says, "One iota, or one tittle, shall not pass from the law until all is fulfilled." For He says, "I did not come to abolish the law, but to fulfill it." Moses himself, who was at once the lawgiver, the high priest, the prophet, and the king, and Elijah, the zealous follower of the prophets, were present at our Lord's transfiguration on the mountain. They were witnesses of His incarnation and of His sufferings, as close friends of Christ, and not as enemies and strangers. From this it is shown that the law is good and holy, and so are the prophets.

Therefore the mother, though superior to the law, submits to the law. And she, the holy and undefiled one, keeps that time of forty days appointed for the unclean. And He who makes us free from the law became subject to the law; and for Him who has sanctified us, a pair of clean birds is offered, in testimony of those who approach clean and blameless. Luke 11:24. Now Isaiah is our witness that that childbirth was polluted by nothing, and stood in no need of expiatory victims. He clearly proclaims to the whole earth under the sun, "Before she travailed," he says, "she brought forth; before her pains came, she escaped, and brought forth a man-child." Isaiah 66:7. "Who has heard such a thing? Who has seen such things?" Therefore, the most holy virgin mother entirely escaped the manner of women even before she brought forth, no doubt so that the Holy Spirit, betrothing her to Himself and sanctifying her, she might conceive without intercourse with man.

...have answered well enough the charges of the many crimes on which these fierce demands are made for Christian blood. We have fully presented our case. We have shown how we can prove that what we say is true, from the trustworthiness and antiquity of our sacred writings, and also from the confession of the powers of spiritual wickedness themselves. Who will dare to refute us, not with skill in words, but, as we have made our demonstration, on the basis of reality? But while the truth we hold is made clear to all, unbelief meanwhile, even at the very time when it is convinced of the worth of Christianity, now well known both for its benefits and from the intercourse of life, takes up the idea that it is not really something divine, but rather a kind of philosophy. "These are the very things," it says, "that the philosophers advise and profess: innocence, justice, patience, sobriety, and chastity." Why then are we not allowed the same freedom and immunity for our teachings that they have, when we are compared with them in what we teach? Or why are they not also forced to the same acts, by refusing which our lives are put in danger, if they are so much like us? For who forces a phil

...ut divinity is the property of the Father. And whenever the divinity of these three is spoken of as one, this bears witness that the property of the Father also belongs to the Son and the Spirit. Therefore, if the divinity may be spoken of as one in three persons, the Trinity is established and the unity is not divided. And the oneness that naturally belongs to the Father is also acknowledged to belong to the Son and the Spirit. However, if someone speaks of one person in the same way he may speak of one divinity, then it cannot be that the two in the one are one in that sense. For Paul addresses the Father as one with respect to divinity, and he speaks of the Son as one with respect to lordship: "There is one God the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, by whom are all things, and we by Him." 1 Corinthians 8:6. Therefore, if there is one God and one Lord, and at the same time one person just as there is one divinity in one lordship, how can this distinction in the words "of whom" and "by whom" be believed, as was said before? Accordingly, we do not speak as though we were separating lordship from divinity, or pushing the one away from the o
