Wow. If adduncan and I are agreeing, something's up around here.
The doctrine of papal infallibility does not mean that everything the Pope says is the word of God. For example, if the Pope rolls out of bed in the morning and says "I like Egg McMuffins" that does not mean we'll be serving them at Mass from now on. Papal infallibility is based on statements the Pope makes when speaking as the Pope the office, not the Pope the person.
The Catholic church does not worship Mary, nor do we worship images or relics. They are there as symbolism, just like how a photo of the Four Founders of Gamma Phi Beta isn't worship or adolation, but respect.
I'll let a better Catholic handle the rest of the issues, should they choose to.
And yes, I am a ROMAN CATHOLIC. I was baptized in a Roman Catholic Church, made my First Communion and Confession at another Roman Catholic Church, and was confirmed at the same church I was baptized at. I also attend a Jesuit school. I might not agree with everything the Pope or my Archbishop says, but it's better than believing Jack Chick.
