It has all the marks of a "cut and paste" document, and some have argued for multiple sources. Torrance argues that a decline in the understanding of grace takes place in the writings of the Apostolic Fathers from that which is evidenced in the apostolic writings themselves ("The doctrine of Grace in the Apostolic Fathers" ), but others have countered that, in the case of The Didache, this is to misunderstand the nature of the document as a piece of pastoral advice addressing specific issues rather than a theological treatment of the nature of saving faith (Aaron Milavec, Te Didache: Text, Translation, and Commentary ).
The fact that Ignatius (in Antioch) was known to be gathering Paul's letters is yet another argument in favor of the Egyptian origin of The Didache.
The story of the "discovery" of the complete text rivals the finding of the Dead Sea Scrolls and Nag Hammadi Library in the early twentieth century.
Along with The Epistle of Barnabas, 1 & 2 Clement, The Shepherd of Hermas, The Epistles of Ignatius and Polycarp, Te Epistle of Diognetus, and The Martyrdom of Clement, Ignatius and Polycarp, The Didache comprises one of the documents of the "Apostolic Fathers" - documents written in the latter half of the first century by early church Fathers known (? The Teaching of the Twelve Apostles, or its subtitle, The Teaching of the Lord Through the Twelve Apostles (neither of which are thought to be original) is known today simply as The Didache ("The Teaching").
A document about a third of the length of Mark's Gospel, The Didache represents the preserved oral tradition of the mid-first century church based in either Antioch in Syria or Alexandria in Egypt (scholars have argued for both).
Thirdly, of considerable interest is the so-called "Gentile Decalogue" (2:2), omitting the second, fourth and fifth commandment and inserting in its place commandments forbidding pedophilia, illicit sex, magic, the making of potions (pharmakeuein) and abortion.
