Where does the Catholic Church get it's authority?
How can I be certain?
Is the Catholic Church going to point to a scripture in the Bible?

Oohh, that is a good point. How did the Catholic Church know about Mt 16:18-19(that's the verse you use isn't it?) if Matthew wasn't written until about 30 years after the Resurrection?

Those would be the versus the catholics site for their authority.

However, I am not catholic.
