Albert Mohler nails it with respect to divorce among evangelicals in this entry at his blog site, Here’s the money quote, though I strongly recommend you read everything at Mohler’s blog:
Evangelical Christians are gravely concerned about the family, and this is good and necessary. But our credibility on the issue of marriage is significantly discounted by our acceptance of divorce. To our shame, the culture war is not the only place that an honest confrontation with the divorce culture is missing. Divorce is now the scandal of the evangelical conscience.
I think it’s really an understatement to say that evangelicals’ credibility is discounted by the way they turn their heads from the rampaging destruction of their own communities by divorce. Homosexuals see heterosexual Christians marrying, divorcing, and remarrying at will. But, the same Christians will deny homosexuals the same freedom of sexual/social congress that these Christians insist is paramount to healthy society.
“But, homosexuality is wrong!! The Bible says so!!
It’s a hopeful sign that voices from the Southern Baptist camp are now heard on this topic. See here for the text of a resolution adopted at the 2010 Southern Baptist Convention meeting in Orlando, Florida, entitled “On the Scandal of Southern Baptist Divorce.”
