Now, most atheists think they want the reverse to be the case, that the canon not being decided until a committee got at it hundreds of years after the fact is the more embarrassing theory, and gives greater authority to the books excluded.
This means all those published opinions before were based on a falsehood.
This means all variants prior to that (including the original form of the text as Josephus wrote it) are permanently lost and invisible to us.
Every error and distortion and mistaken “correction” that got into the text in that one single Eusebian manuscript, from its own copying from an earlier manuscript in that same library (used by Origen), which said significantly different things, and every error and distortion and mistaken “correction” that got into the text in the long process of transmission down through numerous reproductions before Origen even acquired his copy, will never show in the surviving record.
The first time any clear assertion of a canon came from Christian leadership was a letter by Athanasias in 367 A.
D., and all he did was endorse the canon already widely in use (against attempts to usurp or alter it).
