Reform means to rework an existing form. Reform creates no totally new thing. The old form, now reformed, is still a form subject to further reform. Jesus was not a reformer, not a reworker of Judaism to make its rule driven, humanly administered, sacred space obsessed religion into a similar one but now universally applicable. All things have never been made gloriously new under the Orthodox theology of institutional Christianity. In fact the similarities between OT Judaism and Orthodox Christianity far exceed the differences. The greatest of the real differences is the notion of eternal divine torment after death. That is the invention by which Christianity truly distinguishes itself and provides the very basis for its supposed divinely ordained existence and influence.
Remove the fear of Hell from its message and the church is reduced to surviving based on its ability to promote peace, joy, and benevolence in the hearts of its adherents. In other words, they would have to behave like Jesus and deliver the promised benefits of Jesus. They could no longer be political schemers and the judge of the world, for the simple reason that these activities do not contribute to what Jesus promised nor what he demonstrated personally.
Until the church gives up on trying to honor Jesus by ignoring him or trying to redefine him as a warrior/politician, we can reform forever and still miss the mark.
