Apostolic constitutions

The Apostolic Constitutions or Constitutions of the Holy Apostles (Latin: Constitutiones Apostolorum) is a Christian collection of eight treatises which belongs the Church Orders, a genre of early Christian literature, that offered authoritative "apostolic" prescriptions on moral conduct, liturgy and Church organization. The work can be dated from 375 to 380 AD. The provenance is usually regarded as Syria, probably Antioch. The author is unknown, even if since James Ussher it was considered to be the same author of the letters of Pseudo-Ignatius, perhaps the 4th-century Eunomian bishop Julian of Cilicia.

The Apostolic Constitutions contains eight treatises on Early Christian discipline, worship, and doctrine, intended to serve as a manual of guidance for the clergy, and to some extent for the laity. It purports to be the work of the Twelve Apostles, whose instructions, whether given by them as individuals or as a body.

The structure of the Apostolic Constitutions can be summarized:

The best manuscript has Arian leanings, which are not found in other manuscripts because this material would have been censured as heretical.

The Apostolic Constitutions is an important source for the history of the liturgy in the Antiochene rite. It contains an outline of an anaphora in book two, a full anaphora in book seven (which is an expansion of the one found in the Didache), and the complete Liturgy of the eighth book of the Apostolic Constitutions, which is the oldest known form that can be described as a complete divine liturgy.
