That is just flat out wrong. Paul wrote from 50-60AD. There were Churches all over Asia Minor before 100 AD. Constantine himself did nothing, the Canon was all but established by 300AD. The main debate was over books like Revelation, James and 3rd John. The council of Nicea was about settling the argument over the nature of Christ. ie the hypostatic union.
And Paul did not even know Jesus, never met him.
