With a generous hat-tip to a source to remain anonymous, I was pointed toward
this article in
Newsweek magazine on gay marriage. It neatly sums up a far more nuanced approach toward the use of Scripture in public debate. Rather than simply toss out this or that verse from Leviticus or Romans and then say, in essence, "God hates fags", we are given a nice tour of serious thought, scholarly refelction, and an understanding that
"Marriage" in America refers to two separate things, a religious institution and a civil one, though it is most often enacted as a messy conflation of the two.
In other words, the conflation of a civil contract with a religious covenant has led to more confusion rather than less, more heat than light.
The article is long, but I urge anyone interested in the topic to read it in its entirety.
