Personaly, I do not believe the Pope is God on earth and can reveal any new doctrine. I do not believe Peter was the first Pope, he had a wife, and Jesus said on this Rock, meaning the statement Peter said about him being the Messiah, not on Peter's name, which is stone, like a little stone, not rock. The whole foundation for the Church is Jesus Christ, no other foundation is to be laid but that, and that is scriptural. I stand on the word of God alone, Christ alone, faith alone, works being an outward manifestation of that faith, but not the cause of our faith. There is one mediator between God and man, the Lord Jesus Christ, we pray directly through Him, He only can forgive sins, not a priest, Mary offered a sin offering for her sin, she is not sinless, nor to be worshipped, The wafer and the wine do not become Christ's body and blood when we take it, thus pulling him down from heaven and sacrificing him again, he made one sacrifice, once for all and sat down at the right hand of God the Father. I call no man Father, but God, that is scriptural. I add nothing to Christ's payment for our sins on the cross, not faith plus works, sacrements, the church, or anything else, faith alone, in Christ alone, and the word of God alone as my source of authority. But that's just me, disagree if you want, I won't argue, read the Bible for yourself, the BIble, the Bible, the Bible, contains all the answers. PEACE!
