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.
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.
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.
Wicked sons do not have the Holy Ghost in the same way as do beloved sons, and yet they do have Baptism. So, too, heretics do not have the Church as Catholics have, even though they have Baptism.
