Just want to point this out, the Catholic church, which is far and away the largest Christian church, doesn't believe homosexuality to be a choice. The official position of the Vatican, as far as I remember, is that homosexuals just have a different temptation than other people. I mean to say, some people have problems with Gambling, some with Envy, some with Wrath, some with homosexuality. That doesn't mean those people only
have that temptation, of course, it's just the one they struggle with most. Also, when God makes some one homosexual, He's informing them that he wants them to be chaste throughout life. The Vatican also allows homosexuals to be priests, so long as they aren't practicing, if I remember correctly.
Just wanted to make that clear.
