"Jesus would rather kill, not marry, gay people" - Franklin Graham

[Angrboda]

I don't find the article particularly apt, given that it cites that marriage, according to God, is permanent, and divorce immoral.  Hardly something you'll find much adherence to among the Christian faithful, whose reasoning you are defending.

Regardless, neither passage even mentions gay marriage.  Where are the passages where God "unambiguously" forbids gay marriage?

You don't thing the very very clear prohibitions and judgements covers God's opinion on homosexuality and by extension gay marriage?

Well, at least now you're acknowledging that the Christian attitude toward gay marriage is "by extension" of what is in the bible, rather than an affirmation of something actually present in the bible. At least that's progress. I will also note that, contrary to the way you frame your question, the bible actually says nothing about homosexuality, but rather addresses specific homosexual acts, not homosexuality as an orientation. But thank you for acknowledging that the Christian complaint about hating the sin and not the sinner is essentially bullshit. But let's talk about what the bible actually does say. First of all, I have to ask which part of the bible we're referring to here. Because if you mean passages in the old testament, we no longer hold that people are abjured against eating shellfish or wearing cotton-polyester blends either, so I think we can ignore those prohibitions. That leaves us with Paul's statements in Romans, if I'm not mistaken. It's worth noting that neither Paul nor the writers of the old testament had any notion of homosexuality as an enduring sexual orientation, much less any concept of gay marriage as such. So by necessity, the comments against homosexual sex are referring to sex outside marriage. Is it right to extend these statements to statements as to how God feels about homosexual sex within marriage? Can we likewise extend the prohibition against heterosexual sex outside marriage to what it should say about heterosexual sex within marriage? I don't think so. So anyone making such an argument is being ignorant. But beyond that, even if we accepted that the new testament does say something about gay marriage, we need to look at how Christians actually apply the messages of the new testament in order to see if a coherent moral position is being advanced. We note that Jesus explicitly condemns divorcing and remarrying, and he also speaks without censure about slavery. Yet modern Christians take neither message to heart, ignoring what the bible says about divorce, and excusing Jesus' comments on slavery as being merely a product of the time (or perhaps progressive revelation). Yet how do they treat the passages referring to homosexual behavior? They zero in on those passages and extend them to things they weren't even talking about at the time. And why do they do this, but ignore messages about divorce and slavery? I contend it's because they like the messages condemning homosexual acts, and not the others. Christians are picking and choosing what to affirm and what not to affirm based upon prior prejudice, rather than upon anything the bible actually says. And cherry picking which parts of the bible to obey is not a rational procedure no matter how you choose to frame it. The contemporary Christian, rather than being motivated by any hypothetical argument such as you make, is actually motivated by one thing: anti-homosexual prejudice.
