Barack Obama has used the Sermon on the Mount as theological justification for same sex unions, saying that "for [his] faith," its message is "more central than an obscure passage in Romans."
As the author of the linked piece, Terrence Jeffrey of CNS, points out, Barack didn't specify which part of Sermon on the Mount he believes would support his views. But he does include a link to a letter setting forth Obama's views on LGTB matters, which includes the following language:
As your President, I will use the bully pulpit to urge states to treat same-sex couples with full equality in their family and adoption laws. I personally believe that civil unions represent the best way to secure that equal treatment. But I also believe that the federal government should not stand in the way of states that want to decide on their own how best to pursue equality for gay and lesbian couples — whether that means a domestic partnership, a civil union, or a civil marriage. Unlike Senator Clinton, I support the complete repeal of the Defense of Marriage Act (DOMA) . . .
That's pretty radical. It's important to make sure that Barack's views on topics like this get out there, as his views are way left of the American mainstream. It goes without saying that even as cultural conservatives critique those views, it will be important to do so with a tone and in terms that cannot be construed (or misconstrued) as anything other than civil and respectful. Too often, lefties avoid debating on the merits by throwing out accusations of bigotry and hatred -- charges that are amplified and repeated by a media that for the most part understands far too little about social conservatives.
