Is this article by Terence P. Jeffrey:
Sen. Barack Obama (D-Ill.) told a crowd at Hocking College in Nelsonville, Ohio, Sunday that he believes the Sermon on the Mount justifies his support for legal recognition of same-sex unions. He also told the crowd that his position in favor of legalized abortion does not make him "less Christian."
"I don't think it [a same-sex union] should be called marriage, but I think that it is a legal right that they should have that is recognized by the state," said Obama. "If people find that controversial then I would just refer them to the Sermon on the Mount, which I think is, in my mind, for my faith, more central than an obscure passage in Romans." St. Paul's Epistle to the Romans condemns homosexual acts as unnatural and sinful.
Obama's mention of the Sermon on the Mount in justifying legal recognition of same-sex unions may have been a reference to the Golden Rule: "Do to others what you would have them do to you." Or it may have been a reference to another famous line: "Do not judge, or you too will be judged."
Having heard Obama work the Sermon on the Mount into several riffs before, I think Jeffrey, who is apt to want to misread Obama, gets it pretty much right. Obama has Matthew 7:1-6 in mind -- the discourse on judgementalism --
1Judge not, that ye be not judged.
2For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
3And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?
Obama's reference was casual, and in referencing scripture he's committed the same (venial) sin that liberal religionists are always cataloguing as coming from conservatives: that they slip contextless biblical phrases into their political stump speeches and degrade the meaning of both.
Obama does not -- and did not -- use the Sermon on the Mount to justify same-sex marriage. But he gave his opponents a reason to think that he did.
