And if you want to enlighten people about their misunderstandings of your religion, it's probably wise to know the difference between a "statement" and a "question," and, at a bare minimum, decency requires not conflating ignorance of internal concepts like "ex cathedra" to stupidity.
Otherwise, you come across as just another thumpin' asshole.
It's complicated. Many old religions have two components: the popular beliefs and the philosophical part of them. This is true of Catholicism (do not confuse with Christianism), Buddhism, etc.
The philosophical part is complicated. It's not something that you just explain in a couple of sentences on Slashdot, it will take some studying to get the meaning right of many concepts, such as "ex cathedra" or "metaphysical causality".
Going back on the topic of the article, you could read a great comment at the bottom of this story: http://arstechnica.com/science... that gives (IMHO) a great summary of on what the Catholic Church believes regarding evolution and big bang.
