Actually, let's examine the mentions of homosexuality in the NT, and just who it is who says it. His name was Paul. He never met Jesus in his lifetime. His writings also said that the world 'would be ending soon,' and that women should be entirely subject to their husbands in church and at home, and should 'dress modestly,' like Muslim women, among other things that are just bat***t insane. You'll excuse me if I don't find him a credible source, really.
Jesus, however, never said a damn thing about homosexuality. Get your facts straight.
"Modesty" does not mean dressing like a muslim. It means not walking into church wearing jewelry, expensive clothing, and elaborately tressed hair. It does not mean that a woman cannot wear a T-shirt and jeans on a friday afternoon. And he did not say that women should be the subject of their husbands. He said the submit to their husbands, and he told the husbands to respect their wives. It's called being a team. Here's the verse that people love to bring up when they claim the bible is sexist, Colossians 3:18.
"Wives, submit to your husbands, as is fitting in the Lord."
BUT, people never seem to remember the next verse, verse 19.
"Husbands, love your wives, and do not be harsh with them."
If you love your wife, then you will respect her and not do things that she would disapprove of. The husband and wife are meant to be a team, though the husband is supposed to "wear the pants" in terms of being able to provide leadership. Marraiges where leadership comes from the wife are usually troubled, because the husband refuses to be responsible. When the husband and wife do not live in harmony in the way the bible describes, you will either get a marriage where the husband dominates his wife, or a relationship where they do not communicate well or simply do not care about each other's opinion.
The fact that this verse has been used to justify men treating their wives as property is a prime example of what happens when you re-interpret the bible to meet popular standards, which is exactly what the film in questioning is demanding that Christianity do, but in regards to a different subject.
And the world is ending soon, we just don't know when. Whether it happens a year from now or a thousand years from now, it's pretty soon in comparison to the earth's age, whether you believe in an old earth or a young earth.
The question has always been whether or not Christians should be allowed to have a standard that is separate from that of mainstream society, and if you ask true, born-again bible believing Christians, the answer will always be no. But since the earliest days of Christianity, we've always been under pressure to conform, which the Bible explicitly forbids us to.
To the people who dislike the standards that Christianity sets for what is a sin and what is not, I would very much like to know... What act that you, as a liberated individual do not consider to be "bad," would you be OK with Christians labeling as a sin? Because I'd bet that it's a short list.
