1) Really, anyone who tried to print the bible in a language besides latin were executed for heresy? Or were they executed for printing actual heresies, like false translations, eliminating books, etc. I also hear alot about "chaining bibles" so nobody could read them. Which doesn't make sense because one could go to church to read them. Not to mention, books were extremely valuable items back in the day, they were chained so they could not be stolen. I do not condone the execution of heretics in this day and age, but if you want to about it, yall don't exactly have your hands clean there either, buddy.
2) Which is not magic. Unless you consider God to be a magician, in which case I would like to see you refer to God as the grand wizard and all his acts as sorcery.
3) Apostolic Succession is not about having special insight to the bible only allowed to a few (priests). It is about the the granting of authority to administer the sacraments. Which has nothing to do with interpreting the bible.
4) touche. Haha, I wiffed on that one. By arcane I was thinking mystical, not obscure. A better term would have been archaic, but the you were trying to give the impression that catholicism is all a bunch of hokey pokey magic. So I see what you did there. Latin was the international language of the middle ages. It was not "spoken by "no one". It was understood by most, and written by anyone who was literate. It was the lingua franca of the day, and still used at the time of the Reformation. It makes no sense to say that the church used Latin so no one could understand or change its doctrine because then it would be rather pointless to have any message at all, even a nefarious one. Now if you want to talk about its use up until the 60s, well that was obviously the church being stubborn.
