External evidence strongly supports the Matthean authorship of the first Gospel. The earliest copies of the Gospel we have begin "KATA MATTHAION"("according to Matthew"). Several early church fathers referred to Matthew as the writer including Clement of Rome, Polycarp, Justin Martyr, Clement of Alexandria, Tertullian, and Origen.9Papias' use of the term logiato describe Matthew's work, cited above, is not a clear attestation to Matthean authorship of the first Gospel. Since Matthew was a disciple of Jesus and one of the 12 Apostles, his work carried great influence and enjoyed much prestige from its first appearance. We might expect a more prominent disciple such as Peter or James to have written it. The fact that the early church accepted it as from Matthew further strengthens the likelihood that he indeed wrote it.
Internal evidence of Matthean authorship is also strong. As a tax collector for Rome, Matthew would have had to be able to write capably. His profession forced him to keep accurate and detailed records which skill he put to good use in composing his Gospel. There are more references to money and to more different kinds of money in this Gospel than in any of the others.10Matthew humbly referred to himself as a tax collector, a profession with objectionable connotations in his culture, whereas the other Gospel writers simply called him Matthew. Matthew called his feast for Jesus a dinner (Matt. 9:9-10), but Luke referred to it as a great banquet (Luke 5:29). All these details confirm the testimony of the early church fathers.
