A major conservative Christian organization shuttered its doors on Monday after its president, Doug Phillips, resigned from his position in the wake of an extramarital affair. Phillips is an extremely influential leader in the “Biblical Patriarchy” movement, a wing of conservative evangelical Christianity that believes men should have “dominion” over women. Phillips and his organization, Vision Forum, are enormously active in a cluster of related ministries, including the Christian homeschooling movement. The group also advocates against access to birth control and abortion. Even if you don’t know Vision Forum, you know some of its friends: Kirk Cameron, for one; the Duggars, for another.
