What This Chapter Is About
Matthew 5 opens the Sermon on the Mount, the first of five major teaching discourses in Matthew's Gospel. Jesus ascends a mountain (echoing Moses on Sinai), sits (the posture of authoritative teaching), and addresses his disciples while the crowds listen. The chapter contains the Beatitudes (5:3-12), the salt and light sayings (5:13-16), Jesus's declaration that he has come not to abolish the Law but to fulfill it (5:17-20), and six 'antitheses' in which Jesus deepens the Torah's demands — addressing anger (5:21-26), lust (5:27-30), divorce (5:31-32), oaths (5:33-37), retaliation (5:38-42), and love of enemies (5:43-48). The chapter culminates in the command to 'be perfect, as your heavenly Father is perfect.'
What Makes This Chapter Remarkable
The Sermon on the Mount is structured as a new Sinai revelation. Just as Moses ascended the mountain to receive the Torah, Jesus ascends to deliver its definitive interpretation. The Beatitudes reverse worldly valuations — the poor in spirit, the grieving, the meek, and the persecuted are declared blessed. The antitheses ('You have heard... but I say to you') do not contradict the Torah but radicalize it, moving from external behavior to internal disposition. Jesus claims an authority that surpasses Moses: not 'Thus says the LORD' but 'I say to you.' The Greek teleios ('perfect') in verse 48 means 'complete, mature, whole' — not sinless perfection but wholehearted devotion.
Translation Friction
The relationship between Jesus and the Torah in 5:17-20 is one of the most debated passages in the New Testament. We render the Greek as given without resolving the tension between 'not one iota will pass from the Law' and the apparent modifications that follow. The antitheses vary in structure — some quote the Torah directly, others cite popular interpretations ('You have heard it was said'). We preserve these distinctions. The teaching on divorce (5:31-32) involves the contested term porneia, which we render transparently with a note on the semantic range.
Connections
The mountain setting connects to Sinai (Exodus 19-20), the Beatitudes echo the Psalms (especially Psalm 37) and Isaiah 61, the Law-fulfillment passage connects to Matthew's ongoing concern with the Torah's continuing validity, and the antitheses prepare for the conflicts with religious leaders in later chapters. The command to love enemies (5:44) will be tested in the Passion narrative.
**Tradition comparisons:** The Latin Vulgate shaped Western theology here: Beati pauperes spiritu (blessed are the poor in spirit) established the Beatitudes vocabulary in Latin. Beati (blessed, happy) became the standard term for spiritual blessedness. Pauperes spiritu (poo... (3 notable Vulgate renderings in this chapter) See the [Vulgate Matthew](/vulgate/matthew).
