Sorry all my Protestant buds but if you're going to reject doctrines such as papal authority and the perpetual virginity of Mary you ought to reject the canonization of NT writings who were given you by the same folks that gave you the aforementioned doctrines.
Well....I'm not a Protestant but there was no such thing as Papal Authority and the "Infallible" pronouncement of Perpetual Virginity and the RCC when the Bible as we know it today was canonized.
The RCC as we know it today did not exist in the early few hundred years of the "Church".
The retroactive listing of "Popes" and the authority of the RCC is just that - - - retroactive and imaginative.
