I'm Orthodox.
Matt told he believed in something. technically he is an atheist, because he doesn't believe in God. but I think pure atheists believe in noone but themselves, so Matt isn't a true atheist.
about Matt and hell - there's a famous picture by Bosch - The Garden of Earthly Delights, on which we can see that all musicians go to hell. it is unfair I think, because all talents are given by God and people use them to earn money and to make others feel happy. Matt uses his talent very well and as there are so many followers, he can't go to hell.
Greetings from Latvia
I wish you Merry Christmas and Happy New year!
