Denominational Christianity is, at best, only a skeleton of the assemblies represented in the first apostles' administrations. Whether they are called progressive, conservative, moderate, or whatever. If they are lukewarm, what did Jesus say? Evidence like you offered suggests they all are neither cold not hot therapeutics spas. And what does the Bible say about intellectualism and the "foolishness of preaching?" I guess I'm just not understanding nor am not sure what are your Progressive Christianity's tenets in the list usually titled "What we believe." It is my conviction Christianity starts with individuals turning to God, to a personal relationship. to becoming born again as Jesus explained. Intellectual assent accomplishes nothing regarding the Kingdom of God.
