Some will protest that we must have faith in the Bible, and that the Bible takes an unfavourable view of intimate same-sex relationship. But I would answer that Christian faith is not an uncritical repetition of a received text. It is a mindful commitment to the power of love, to which the text seeks to give witness. Every generation of the Christian faith must decide how they will honour that demand of love in the living of their days. Changing circumstances and changing ideas are not the enemy of faith.
I guess some tradition-loving "conservatives" can support gay marriage after all.
