Or: both are important, and the answers to one might have implications for determining the answers to the other, and vice versa.Is this question of who really occupied the shoes of the so-called Jesus the most salient?
Is not the teaching, the lessons and the message more important to suss out? What IS the living water? If Christ is the vine and we are the branches, then how do we become more cognizant of that living presence in the current moment? What is meant by the way to salvation? (and a thousand other questions about what really is Christianity)
Our lives and souls as humans are hanging in some kind of balance.
How can the real genuine teaching be accessed and absorbed and acted upon in the now?
And not so much, "who was the real teacher?"
My guess is that even the teacher, be it Caesar or Salad, would agree.
