Circular Reasoning

well; this is the RCC Forum, and I have yet to see any RCC'er
prove that the Church of Rome is what they claim
without using "circular reasoning"
Have you seen them try to do it with circular reasoning? I don't think those sorts of things are proven with only logic. Faith is beyond logic, and faith forms the basis for most religious beliefs. That is why I think using terms from formal logic, like "circular reasoning" is not the best way to describe religious thought.
