Well, let's distinguish religion from spirituality. I am Catholic, so religion for me is a way of having discipline and collective worship with persons who share the same mystery.
I have never been brought up a Catholic - I mean, a Roman Catholic - we're all Catholics, aren't we? We're Protestant Catholics, whether we're from Methodist or Baptist or what.
I was raised a Catholic and when you're raised a Catholic they don't teach you to think for yourself. You're taught not to think too deeply about things.
I read in the newspaper that the Catholic Church finally decided that it had been theologically improper to try to convert the Jews. Whoops! Sorry for all those inquisitions, crusades, and autos-da-fe. Previous popes were wrong - infallible, perhaps, but wrong.
