In historical use by: Ethiopian Orthodox (broader canon); Syriac Orthodox (as Books I-II of the Clementine Octateuch) — A church-order text presented as the risen Lord's teaching to the apostles, preserved in Syriac and Ethiopic. In the Ethiopic tradition it is counted among the church-order books of the broader canon; in Syriac the two books together form the first two books of the Clementine Octateuch. No major church uses it as an active liturgical manual today; it is studied chiefly for early Christian worship and baptismal practice.
Continues under the same pseudonymous framing of teaching given by the risen Christ to the apostles, likely by the same unknown author(s) and from the same period of composition (proposals ranging from the 2nd to 5th century AD, with the 4th-5th century most favored). Further instructions on church discipline, worship, and the conduct of clergy and congregation.
