The Catholic Church, founded by Jesus, teaches no false doctrines.
Outside the Church you find a multitude o contradictory doctrines on central matters of the faith.
The Church is protected against teaching error.
No false doctrines and no errors? Really?
So, you don't think Martin Luther had good reason to object to much of Catholic doctrine? (The sale of indulgences for example) You don't believe it was a false doctrine to teach people that they can buy their loved ones a place in heaven?
And what about praying to Mary to intercede and guide Christians? Where did Jesus (or any of the disciples or Paul) teach that His followers are to go to Mary in such a way?
What about praying to saints? Where in Scripture is this taught? Where does it say that there should be patron saints for certain causes that Christians can go to with their concerns and requests? Does the Bible not say that we have ONE Mediator, Jesus Christ?
What about penance or purgatory? Where are these Catholic doctrines found in Scripture? Is the work of Christ on the cross enough, or does Scripture teach that we must make ourselves right with God by doing so many Our Fathers and Hail Marys, or by going to a place where our mortal sins are burned away so we can enter heaven?
What about the veneration of relics? Where is this taught in Scripture? Or the use of icons?
Much of the Catholic doctrine and tradition that you claim is absolutely without error is in fact entirely and inexcusably contrary to Scripture and the teachings of Jesus Himself.
It's mind boggling to me that you believe the Catholic Church has never taught anything of error, and that it hasn't lied and mislead people. (And in fact punished those who disagree, even unto torture or death).
I think you need to do some honest and careful research into the history and present day practices and teachings of the Catholic Church, in comparison to the word of God. (Which is of higher authority than ANY church teaching or tradition, including those of Protestant churches).
And, just so we're clear, I'm not saying Protestant churches are without fault in this regard. In fact, I have started several threads on these forums about my concerns with much of what is going on in many Protestant churches today.
There is no one perfect denomination, because denominations are made up of people, and people are not perfect, we make mistakes.
