Pardon my curiosity, I was raised Roman Catholic and in reading various threads and watching some portions of the series Big Love I see many similarities between the two faiths. Both require their believers to go out on missions. Both seem to be very closed off from outsiders, i.e. they don't seem to socialize outside of the faith. Both seem to have an emphasis on prepping. I am not trying to be insulting or a wise guy, I was just wondering if they are basically the same faith the way Catholicism and Eastern Orthodoxy are.
