Jesus and the Law of the Prophets

Matthew 5:17-20 is the programmatic center for interpreting the antitheses that follow. Jesus explicitly denies coming to "abolish" the Law or the Prophets and says instead that he came "to fulfill" them. The verb plēroō can denote bringing something to completion, realizing its intended meaning, or accomplishing what Scripture anticipates. Scholars consequently differ over whether Matthew emphasizes Jesus' obedience to Torah, his realization of Scripture's prophetic trajectory, his authoritative disclosure of Torah's fullest intent, or some combination of these.

The saying about not one iōta or one keraia passing from the Law uses the smallest Greek letter and a tiny written stroke to emphasize continuity. Yet the qualifying clauses "until heaven and earth pass away" and "until all has happened" generate debate about temporal scope. Matthew simultaneously affirms the Law's abiding significance and presents Jesus as possessing authority to define its proper observance. The following contrast with "the scribes and Pharisees" concerns a righteousness that must "exceed" theirs. This need not mean greater numerical accumulation of rules; within the chapter, the contrast moves toward integrity extending to anger, desire, truthfulness, retaliation, and enemy-love. The passage therefore resists readings of 5:21-48 as simple cancellation of Torah.

Matthew 5 opens the Sermon on the Mount, the first of the Gospel's major teaching discourses. Jesus ascends a mountain, sits in the posture of a teacher, and addresses disciples in the presence of the crowds introduced at the end of chapter 4. The chapter moves from the Beatitudes to images of salt and light, then to a programmatic statement about Jesus' relation to the Law and the Prophets. Six subsequent units illustrate the kind of righteousness Jesus demands by treating murder and anger, adultery and desire, divorce, oaths, retaliation, and love of enemies.

The chapter's central interpretive question is how Jesus' teaching relates to Israel's Torah. Matthew explicitly denies that Jesus abolishes the Law and instead speaks of fulfilling it, while the repeated formula "you have heard ... but I say to you" presents Jesus as an authoritative interpreter whose demands reach beyond external conformity to dispositions, intentions, and reconciled relationships. The chapter therefore develops themes introduced earlier in Matthew: kingdom, righteousness, fulfillment, discipleship, and Jesus' distinctive authority.
