The Pun Tyrant
Dude that´s about as wrong as you can get. It´s right in the name of the religion. CHRISTianity. The source for christianity´s being is Jesus Christ. Son of God, God Himsef, and founder of the Christian Church, who appointed St. Peter as the first Pope with the words "You are Peter and upon this rock I build my church" followed by "Truly I tell you, whatever you bind on Earth shall be bound in Heaven and whatever you loosen on Earth shall be loosened in Heaven."The Bible is the sole source of Christianity's entire being.
Even the Bible specifically states the authority of the Pope, only further condensed by the sending of the Holy Spirit and pretty much everything between Jesus and the Apocalypse books (I am missing the name right now), is dedicated to the Church and clearly shows the dogma being defined and discussed within it.
The words you have mentioned are against heresy. Not against the fundamental institution of the Christian Faith.
I´m still waiting for it(Although there is clearly one there, which we could discuss if you'd like)
