This work was edited by J.M. Harden. It is one of the least known of a number of similar documents that have come down to us from comparatively early times. It has been preserved by the Monophysite Church of Abyssinia. It has been said to be a somewhat rambling discourse on Church life and society.

It is claimed to be a message to the Church from the Twelve Apostles assembled in Jerusalem. It deals with such topics as morality, studying the Scriptures, strict obedience of the Seventh Commandment, mutual duties of husband and wife, offices and duties of Christian ministers, and other topics. There are forty-three chapters.

This edition was published by The Society for Promoting Christian Knowledge in 1920.
