>> If the SHEPEHRD OF HERMAS was in the 4th century bibles why is it not in it today. <<
"The Shepherd of Hermas" was not in 4th century bibles. Nor was it ever included with the Old Testament. Along with "The Teaching of the Twelve" (Gr., "Didache"), it was considered by many 2nd-century churches to be "writings suitable for the spiritual formation of converts," and included in publications of apostolic writings. Most such books, with those two exceptions, later became known as the New Testament. Unlike other non-biblical works, such as the Gnostic gospels, these two books were never condemned by name as impure, but were not included in the bible when various councils of bishops set forth the New Testament canons in the third and fourth centuries.
