***Plus you have books like the Shepherd and the Didache.****
The Shepherd was ditched because it said you were allowed ONE SIN after being baptized. It is found in the Alexandrian codex.
You can find these tales in THE LOST BOOKS OF THE BIBLE. they were never lost and were not put in the Bible for a very good reason.
The Didache was more of an instruction book. It would still carry more weight than the Shepherd.
The other one that has received significant support is 1 Enoch. What is your thoughts on that one?
