Although the New Testament canon came after Constantine, I do not find any evidence the Emperor had any say in the compilation of Books.<quoted text>
So you do not hold Emperor Constantine's approved collection of texts as the sole authority regarding Jesus and God ?
Good for you! There are over 100 early Christian texts just as valid as any in the NT. Constantine and the Roman Church banned and suppressed them 300 years after Jesus died.
Prior to that Christianity flourished in a variety of forms throughout Egypt, the Middle East and Europe.
Your second assertion that that the 'Roman Church' banned and suppressed them (certain Christian writings) is unfounded.
However, the Roman Empire did destroy countless Christian scriptures before God converted them.(See the persecution that began on February 24th, 303 AD. Its a miracle that Christianity survived the period from then until 313 AD)
