The Apostolic Fathers, Vol. 2: Epistle of Barnabas/Papias & Quadratus/Epistle to Diognetus/The Shepherd of Hermas

Here are the Letters of Ignatius, bishop of Antioch, among the most famous documents of early Christianity; these letters, addressing core theological questions, were written to a half dozen different congregations while Ignatius was en route to Rome as a prisoner, condemned to die in the wild-beast arena.

Also in this collection is a letter to the Philippian church by Polycarp, bishop of Smyrna and friend of Ignatius, as well as an account of Polycarp's martyrdom. There are several kinds of texts in the Apostolic Fathers collection, representing different religious outlooks. The manual called the "Didache" sets forth precepts for religious instruction, worship, and ministry.

The Epistle of Barnabas searches the Old Testament, the Jewish Bible, for testimony in support of Christianity and against Judaism. Probably the most widely read in the early Christian centuries was "The Shepherd" of Hermas, a book of revelations that develops a doctrine of repentance.
