By Whose Authority...?
I'm not so sure that Jesus advocated for highly organized religion, or if He didn't. The point is that what He did advocate was a new state of being and a new way of approaching life, which had not been taught by organized religion. (A good place to start is Matthew 5,6, and 7.) His fiercest opponents were always the hierarchical traditionalists of organized religion, who seemed to have a pony in the race of who calls the shots, and who were always calling into question the authority by which He taught, performed miracles, and made His claims. It would seem that if organized religion provided the answer to the challenges which they themsleves posed, the answer should have been self evident, as well as Jesus' true identity.
