The Ante-Nicene Fathers, Volume 8. THE TESTAMENTS OF THE TWELVE PATRIARCHS, EXCERPTS OF THEODOTUS, TWO EPISTLES CONCERNING VIRGINITY, PSEUDO-CLEMENTINE LITERATURE, APOCRYPHA OF THE NEW TESTAMENT, THE DECRETALS, MEMOIRS OF EDESSA, REMAINS OF THE SECOND AND THIRD CENTURIES
This book is mostly a collection of the pious (or less-pious) historical fiction of the early church. And, like its modern equivalent, most of the works in this book are of no literary value and even less theological value. The sole exception is the last section made up of fragments and remnants of the first three centuries of the church. And yet, even those don't really count since they are mostly collected from later sources (usually Eusebius). So although some of these last bits are quite good, they're also going to be encountered again later in the series.
With that said, the one use this book might have is to people who are interested in seeing where some of the superstitious and pseudo-pagan practices that exploded in the church in later centuries got their beginning. That's not to say we see fully-developed Medievalism here, just that you can see the stories that form the foundations for later false beliefs and practices.
Otherwise, don't waste your time with this huge volume.
Quite a mix of biblical exposition, philosophical wrangling, ecclesiological instructions, and early church history. The highlight for me was "The Acts of Andrew", from pages 511-516, an amazing example of a martyr bearing bold and winsome witness.
