Of course, let's not forget what Calvin would have said about our sexuality debate. The historical Calvin was so puritanical, he even condemned excessive lust for one's own wife. It's not that Calvin never considered today's "progressive" sexuality - he explicitly rejected it.
Speaking as a lone Calvinist at a staunchly Lutheran (LCMS) institution, it is obvious to me that our professed adherence to Calvin is only window dressing by comparison. For my colleagues here, "What would Luther say?" is a boundary it is almost impossible to cross.
