Matthew's Gospel presents Jesus as the Jewish Messiah who fulfills Old Testament prophecy. The famous "formula quotations" — appearing roughly ten times with variations of "this was to fulfill what was spoken by the prophet" — establish Jesus's life and ministry as the culmination of Israel's hopes (Matthew 1:22-23, 2:15, 2:17-18, 4:14-16, 8:17, 12:17-21, 13:35, 21:4-5, 27:9-10). The Gospel opens with a genealogy tracing Jesus's descent from Abraham through David (Matthew 1:1-17), immediately establishing his credentials as the Davidic Messiah.
The structure suggests a deliberate literary design, often characterized as five major teaching sections (chapters 5-7, 10, 13, 18, 24-25), each ending with a similar formula: "When Jesus had finished saying these things" (Matthew 7:28, 11:1, 13:53, 19:1, 26:1). This fivefold structure may deliberately echo the five books of Moses (the Pentateuch), presenting Jesus as the new Moses who authoritatively interprets God's law. The Sermon on the Mount, delivered from a mountain like Moses at Sinai, repeatedly contrasts Jesus's teaching with previous understanding: "You have heard that it was said... But I tell you" (Matthew 5:21-22, 27-28, 31-32, 33-34, 38-39, 43-44). Each of the five teaching sections is then followed by an action block: Miracles, healings, and other events, reinforcing the teaching sections.
Matthew's Gospel shows particular concern for the church (Greek: ekklesia) — a term appearing only in Matthew among the Gospels (Matthew 16:18, 18:17). The famous confession of Peter and Jesus' promise to build his church "on this rock" appears only in Matthew (Matthew 16:16-19), as does the extended discourse on church discipline and reconciliation (Matthew 18:15-20). This ecclesiastical focus suggests the Gospel was written for a community grappling with questions of authority, membership, and discipline.
