1) The Gospel of Matthew was written for a Jewish-Christian community around AD 80-90 in Antioch. 2) It uses the Gospel of Mark and the hypothetical source Q as source material, arranged in a classical biography format to present Jesus as the fulfillment of Jewish prophecy and model for Christian living. 3) Matthew's community was seeking to secure its identity on the margins of both the Roman Empire and Judaism, so the Gospel legitimates and guides the community's values and lifestyle through the words and deeds of Jesus.
