Of course, the real truth is that the Bible doesn't say a word about loving, committed same-sex relationships. Any condemnation there is for abusive and coercive homosexual practices - excess lust, gang rape or unnatural acts committed by heterosexual men.The truth is that 100 years from now, either in this world or the world to come, history will record that those who conformed their beliefs to the culture were nothing more than a passing curiosity, while those who refused to compromise truth will be regarded as the spiritual heroes and torchbearers.
The truth is that 100 years from now, Christians are going to look back at using the Bible to justify bigotry and discrimination against LGBT folks with the same shame as we look back at Christians using the Bible to justify slavery and the subjugation of women.
Gay marriage is a human rights and human dignity issue. And the Bible is never - NEVER - on the side of those seeking to oppress a minority group.
