when in your estimation did the Roman Catholic Church begin and who started it?
It was a concept that developed when the early Bishops of Rome, felt they should be the final arbiter of church disputes and therefore the leaders of the church, claiming the heritage of Peter and Paul.
you mean like Clement writing an Epistle to the Corinthian Church in the late 1st century ( while St John was still alive ) correcting them and the Corinthians read the Epistle in Church as Scripture for 100 years?
