Yes under the guidance of the Holy Spirit.
And through the Holy Spirit that authority was given to Peter.
So that would explain why the reading of the Gospel of Peter was rampantly being read, not in Gnostic churches but in the “good ones.”
And that would explain why this Gospel was found buried with who probably was Coptic elder in his local chrch.
And that would explain why the reading of the Revelation of Peter was rife all over the Roman Empire and not in the bad churches but in the “good ones.”
The Clermont List reflects what was considered scriptural in Alexandria in c. 300 A.D., and it contained the Revelation of Peter. And don’t forget that the Muratorian Fragment reflects what was considered scriptural in Rome c. 180 A.D. and it includes...wait for it... the Revelation of Peter, too!
Obviously they were being led by the Holy Spirit?
And let’s not forget that the earliest Greek Manuscripts available to us (Codex A, S and B) contains books that Protestants, Catholics and Ethiopic Christians do not consider to be canonical.
Obviously the Holy Spirit was leading them when these were compiled?
