The Teaching of the Twelve Apostles: The Lord's Teaching Through the Twelve Apostles to the Nations

The Didache or The Teaching of the Twelve Apostles (Didachē means "Teaching") is a brief early Christian treatise, dated by most scholars to the late first or early 2nd century.[2] But J.A.T. Robinson argues that it is first generation, dating it c.40-60. The first line of this treatise is "Teaching of the Lord to the Gentiles (or Nations) by the Twelve Apostles The text, parts of which constitute the oldest surviving written catechism, has three main sections dealing with Christian ethics, rituals such as baptism and Eucharist, and Church organization. It is considered the first example of the genre of the Church Orders. The work was considered by some of the Church Fathers as part of the New Testament but rejected as spurious or non-canonical by others, eventually not accepted into the New Testament canon. The Ethiopian Orthodox Church "broader canon" includes the Didascalia, a work which draws on the Didache.
