It’s great that some theologically conservative evangelicals are making the “biblical” case against Christianity’s historic anti-gay position. There are certainly many people–and not just in evangelical churches–who feel in good faith that they can’t accept a revision of the traditional view without sacrificing their trust in the Bible or other bedrock convictions.
But at the same time, most of the arguments mentioned in the article linked above boil down to saying that
(1) what the biblical authors (especially Paul) condemned is not the same thing we are talking about when we discuss monogamous same-sex relationships and
(2) the Bible’s “moral logic” or its “underlying values” point toward an affirmation of loving, mutually enriching, stable relationships, whether they be opposite- or same-gender.
I happen to think this is basically correct, but it’s also what more liberal scholars have been arguing for decades. It’s understandable that evangelicals would want to make the case to their co-religionists in a cultural and theological idiom that they’re more likely to accept, but this isn’t a substantive departure from the “revisionist” case that has been made in mainline Protestant churches. Framing it that way reinforces the view that mainline scholars and leaders don’t take the Bible and Christian theological tradition seriously and have just capitulated to “the culture.” But in fact, the decisions of churches to embrace full equality for gays and lesbians have typically been informed by painstaking biblical scholarship. This scholarship has led to essentially the same conclusions that are now being used by evangelical revisionists. Obviously not everyone has been convinced, but that’s not because the case hasn’t been made until now.
