According to the first report from Brad Waggoner, the new leader of SBC's Lifeway Research, 10% of SBC Pastors are 5-point Calvinists. See the BP article. The study was based on a sample of just 413 pastors (I can just hear someone now saying they made calls from the Founders' phone contact list). From my anecdotal experience that does seem a bit high. But who knows? In another surprising find, the study also says that Calvinistic SBC pastors are not just young but come from all ages.
