predated the fixing of the Biblical canon by 200 - 300 years
Another red herring argument that should be noted.
2/3 of the canon of a Scripture was set before the birth of Christ.
the Epistles from the Apostles were circulated among NT Assemblies while the Apostles were alive.
Peter identified Pauls writings as Scripture.
the Roman canon was re-examined on several occasions and errors corrected.
And most importantly, the same Holy Spirit that inspired Scripture, preserved Scripture. He is still alive and faithful today.
The Holy Spirit is guiding the Church.
"And most importantly, the same Holy Spirit that inspired Scripture, preserved Scripture. He is still alive and faithful today."
Triple Amen.
