The Apostolic Church-Ordinances is a 3rd century pseudo-Apostolic collection of moral and hierarchical rules and instructions, compiled from early Christian sources. It was first published in Ethiopic by Hiob Ludolf (with Latin translation). It served as a law-code for the Egyptian, Ethiopian, and Arabian churches, and rivalled in authority and esteem the Didache, under which name it sometimes went. Though of undoubted Greek origin, these canons are preserved largely in Coptic, Arabic, Ethiopic, and Syriac versions.
