The Illusion Of Progressive Christianity?

The leading Christian progressive organization, Sojourners, has rejected the above ad, featuring a pastor welcoming a family with two moms. Dan Savage summarizes:

If progressive Christians can't unite behind the concept of welcome then, gee, what the fuck good are they? … The ad doesn't endorse gay marriage. It recognizes the existence of same-sex couples and the fact that many gay couples are raising children and it endorses welcoming them. Just welcoming them. A gay wedding doesn't break out, no rice is thrown, no bouquets reeking of the gay agenda are tossed, no groomsmen are bent over and fisted. It welcomes gay couples and their children—most of whom will grow up to be straight—to come to church and meet this Jesus person they've heard so much about. The same Jesus who welcomed lepers and prostitutes and Samaritans.

David Sessions glimpses the larger picture, and what it means for Jim Wallis, head of Sojourners and one of Obama's spiritual advisors:

Sojourners' attempts to keep the discussion balanced has inflamed progressive Christians, some of who say it is time for their movement to reconsider letting Wallis do the talking in Washington. Jim Naughton, who was involved in the Washington diocese of the Episcopal church and now operates a small communications firm, said people inviting Wallis to policy briefings and White House meetings should realize that he "is far to the right of the people he's allowed to speak for." And now, when liberal Christians "are making progress by the second," he added, is a particularly bad time to hedge on the church's welcome of gays and lesbians.
