I certainly do not deny the history of the Church. That is, of course, why I am not Catholic.
I do believe that the Apostles knew more than a bunch of 21st century Southern Baptists, but I also believe they know more than a bunch of 21st century Catholics.
When I read my Old Testament, I can see how the church established by Moses was corrupted by the time Jesus arrived on the scene. He had little regard for their rules and traditions. It is my firm belief that he has the same opinion of the rules and traditions of the Catholic Church.
I wish you would offer some concrete reasons, facts, to back your claims. Thus far, you have offered none. But your ignorance is glaringly obvious: Jesus was an observant Jew Who fulfilled the Law, not someone Who rejected it.
Our Lord's teachings show that God's revelation was gradual and it is His interpretation of it that is more complete. The OT is not corrupt; it is obsolete (Heb 8:13).
People are corrupt by nature and they will corrupt everything, including the faith. That corruption is even in the translations of the Bible you read. Show me one church whose memebrs are not corrupt or else find a better argument.
