Now, I didn't want to offend Catholics with that question. I was kind of flip when I asked it and I shouldn't have been, but it was to illustrate how easy it is to find fault with another's faith since that's what he was doing.
I am curious though and now that the question is out I would be very interested in a serious response.
For the record, I stick by what I said earlier about believing that the important thing between Christians of various religions is the Christian part as opposed to the religion part, so I'm not going to knock Catholics for practicing their religion differently than I practice mine.
