Manuscript Tradition 
The Sahidic translation is found in British Museum manuscript or.1820, dated 1006, and was published in 1883 by Paul de Lagarde. A new edition was published in 1954 by Till and Leipold The Sahidic version lacks of some prayers found in other manuscripts.
The Arabic translation is complete and dates to before 1295 CE. It is found in Vaticanus manuscript ar.149, and was published in 1904 by George William Horner. Later editions were published by J. Perier in 1912 and Turnhout in 1971.
The Ge'ez translation, which dates from the 13th century, is a complete copy of the original with additional interpolations. It is found in British Museum manuscript or.793, and was published in 1904 by George William Horner.
The more ancient translations are the Sahidic and Arabic versions (probably both coming through a common lost Sahidic version of about 500 CE). The Ge'ez version is derived from the Arabic one
- Book 1 includes the Apostolic Church-Order
- Books 2 and 3 include the Egyptian Church Order (better known as Apostolic Tradition)
- Books 4 to 7 include the eighth book of the Apostolic Constitutions, without the last chapter (Canons of the Apostles) and without the liturgical prayers.
The numbering of the chapters is different in each version. The Sahidic and Bohairic versions divide the Apostolic Church-Order in 30 chapters, while the Arabic and Ge'ez versions divide it in 20 chapters. The Sahidic and Bohairic versions have the Apostolic Tradition from the 31 to 62, while the Arabic and Ge'ez versions from 21 to 47.
