Hi David.
I am fascinated by both figures. My fascination with Jung derives from my personal experiences. Also we have direct access to his writings and his life.
Jesus is more difficult, since he never wrote anything that we are aware of, and his life and its meaning have been interpreted in many different ways. My fascination with him is therefore an attempt to get to the bottom of who he truly was. I'm not prepared to accept without further investigation the version that the Roman Church came up with.
