Nomocanons (manuals of law) in Eastern Christianity give insights into the whole civil and religious life of communities, families and individuals. Nomocanonical literature is particularly abundant in the Coptic tradition, and the Rev. Franz Joseph Cöln describes five Nomocanons of the Coptic Church with a short account of their contents.

Franz Cöln publishes here an anonymous treatise that deals with the topic of church authority from the perspective of the Syriac tradition. Cöln publishes the Arabic text of the treatise and includes a Latin translation and a brief introduction.

The Nomocanons of the Eastern Orthodox traditions are valuable historical sources for the church traditions they represent. Franz Cöln presents here the collated text of a Nomocanon attributed to Miha’il of Malig and preserved in Garshuni and Arabic manuscripts.

Franz Cöln presents here the Arabic text of an anonymous writing defending the beliefs of the Jacobite Church against the beliefs of other traditions. The text includes a critical apparatus and is accompanied by a German translation.
