If you knew anything about religion, you would realize that it was Jesus,not a corrupt Pope,who originated infallibility...He gave to Peter the keys to the kingdom of heaven...whatsoever you bind on earth will be bound in Heaven and whatsoever you shall loose on earth shall be loosed in Heaven...I will be with you from now until the end of time. Why would Christ want to be associated with an error prone organization?...The Popes seldom speak Ex Cathedra, that is without error, but when they do...it is without error. Find one example refuting that statement, and the entire infallibility question is moot.
