"Who had this knowledge specifically? I am glad for Calvin's work and scholarship, too, but who had this knowledge after the Apostles died or were martyred."

If I read your question correctly, I think you are actually asking something else quite different from the question posed. I think, you are asking, "Who might we read about who was notable and published books now in existence who had this knowledge?" Right?

Otherwise, Tom the tailor, Dave the sheepherder, Steve the mason.

So you are surmising that the knowledge existed and needed to be rediscovered?

Are there Church Fathers who wrote the truth or do we have shards or scraps post-Apostolic age writings that were suppressed?

Or is the truth an esoteric knowledge passed along from commoner to commoner?
