Joseph Backholm, executive director of the Family Policy Institute of Washington, points out that 39 percent of Protestants support same-sex marriage, and this puts them on the wrong side of the debate. “For a Christian,” says Backholm, “the inability to get this question right brings into serious question the ability to get anything right, biblically speaking. You can’t do calculus if you don’t know how to add or subtract.” He believes the job of church leadership is to train the church to think biblically about everything.
