The Gospel of Matthew begins by depicting Jesus as the focus of the history of Israel and ends with Jesus commissioning the creation of a new community composed of people from all nations (the church). The center of the gospel is Jesus the Messiah, but he stands between two communities, Israel and the church. In this study, the author proposes to examine the christology of Matthew's gospel by exploring the theme of Jesus' solidarity with his people, focusing on Jesus' representative role in his relationship both with Israel and the Church.
