Once upon a time, it was fun to skewer liberal Christianity. In the 1930's, Reinhold Niebuhr famously observed that liberal Protestantism preached "a God without wrath who brought men without sin into a kingdom without judgment through the ministrations of a Christ without a cross." More recently, in one of my favorite lines, somebody whose name I cannot track down said that liberal Christians (among whom we should count Catholic progs) would rather be the world's missionaries to the Church than the Church's missionaries to the world.
