This book maps the relationship between Matthew's Gospel and the Didache.

While scholars agree that some form of relationship between these two texts must exist, no consensus regarding the precise nature of this relationship has yet been agreed. At the same time, serious consideration has never been given to the possibility that Matthew's Gospel was written with direct knowledge of a text substantially similiar to the single extant manuscript of the Didache.

If it may be shown that Matthew had direct knowledge of the Didache, then a number of significant implications follow, for example: new evidence is brought to bear on the Synoptic Problem; insight is gained into the pattern of first century Christian liturgical practice and belief; and a detail is uncovered in the story of Gentile incorporation into the Jewish form of the Jesus movement.
