The
Decretum exists in a number of
recensions of varying lengths. The longest has five chapters, another recension has the last four of these chapters, another the last three, and another the first three. The
Decretum's canon of Scripture is thus identical with the Catholic canon issued by the
Council of Trent. • a short endorsement of the supremacy of the
Bishop of Rome over the other bishops, citing the authority of Peter, and a statement of the order of precedence of the three principal episcopal sees: Rome, then
Alexandria, then
Antioch. • a list of writings that are "to be received": the decrees of the first four ecumenical councils, and the writings of the
Church Fathers and ecclesiastical writers mentioned in the chapter, varying from famous to obscure (for example
Sedulius and
Juvencus). Notably, it suggests that while
Origen of Alexandria's work can be read, he personally should be rejected as a "schismatic". • a list of writings that are "not to be received": many early Christian gospels, acts, apocalypses and similar works that are part of what we know as the
New Testament Apocrypha. Mentioned are:). • the Apocalypses of
Paul,
Thomas, and of
Stephen. • the
Testament of Job, the
Apocryphon of Jannes and Jambres, the
Lots of the Apostles and the
Letters from Jesus to Abgar and from Abgar to Jesus.
Attribution The various recensions of the
Decretum appear in multiple surviving manuscripts. It is "attributed in many manuscripts to Pope Damasus (366–384). In other and more numerous manuscripts the same decree occurs in an enlarged form assigned within the documents in some cases to Pope Gelasius (492–496), in others to
Pope Hormisdas (514–523), and in a few cases the documents are simply anonymous."
The Damasine recension In the Damasine recension, there is no mention of pope Gelasius. Though the date of the Roman Council is not mentioned in the
Decretum, the view that came to prevail was that it was the council held in 382: "In 1794 F. Arevalo, the editor of Sedulius, started the theory that the first three of these five chapters were really the decrees of a Roman Council held a century earlier than Gelasius, under Damasus, in 382 A.D."
The Gelasian recension Another recension contains only the last three chapters and is prefaced by the sentence: "Here begins the decretal 'On books to be received and not to be received' which was written by Pope Gelasius and seventy most erudite bishops at the apostolic seat in the city of Rome". Here the focus is on the books and the
Decretum is considered to be a
decretal of Pope Gelasius. In the Gelasian recension there is no mention of Pope Damasus and the Council of Rome. ==Traditional view==
