"...[A]ll of the theological constructs that we have built up around it."
Doing that leads, logically, to no Church and no Scripture from which to derive anything.  It becomes a few people (or even a great number) following the ostensible teachings of one person without any trust that something greater exists for those efforts.  Why should I love another as I have been loved?  How shall I know that this exemplifies a true teaching?  What is the purpose of doing so beyond a sort of personal "self-actualization"?  Is Maslow, then, the Latter Day Jesus?
Jesus is God or He isn't.  If he isn't, why bother to follow Him?  Judaism makes more sense, in that case, and the "better way" is simply the offering of a prophet.  If He God, He came for more that a simple prophet could give us.  What might that be?
Which is it?
