Dating the gospel of matthew
by Maxim Cardew The author of the Gospel has traditionally been identified with “Matthew,” who according to this Gospel is one of Jesus’ twelve disciples (see Matthew 9:9; he is called “Levi” in Luke ).
The main source of this tradition is Irenaeus (a second-century bishop) who writes: “Matthew also issued a written Gospel among the Hebrews in their own dialect” (Against Heresies 3.1.1).
The material from Mark was either supplemented with the Q document (as posited by the dominant ).
Per church tradition the author was Matthew the Apostle, although there is no evidence to support this attribution.
Quickly the narrative moves to Jesus' time in the trenches challenging Satan, his collection of disciples, and the teachings he passes onto the Jews.
There are, however, important arguments against identifying the author as a Jew.
It is also possible that Papias (another second-century bishop) refers to this tradition: “Matthew put together the oracles [of the Lord] in the Hebrew language” (quoted by Eusebius, in his Church History, 3.39.16).
