‘The Teaching of the Twelve Apostles’: a brief manual in Greek, of unknown authorship, comprising instruction about conduct and Church order. It contains quotations from the Sermon on the Mount. It is probably to be dated early in the 2nd cent. CE and composed in Syria. It includes liturgical directions (e.g. a version of the Lord's Prayer, and instructions about baptism) and regulations about travelling bishops, prophets, deacons, and itinerant preachers. Cf. 1 Cor. 12: 28 and 1 Tim. 3: 2–13. Highly valued, a complete Greek MS of the work (dated 1053 CE) was found in 1873, and provoked an intense scholarly discussion.
