I'm not either. Take present-day Christianity, for example: There are those who believe in literal Biblical interpretation, and there are certain denominations that hold to a more humanitarian/parable view of the Bible.
In my mind, Yoda and Ben were "literalists", in that the Force was an energy field, etc. Qui Gon was more "liberal" in his interpretation, just like his rejection of using the Force as a way to look to the future. His only focus was "the living Force," which focused on the present, the here and now.
Which, again, has correlation in Christian denominations: Those who look to "going to heaven" vs. those who want to use Biblical teachings to make TODAY better.
Since the Jedi were all but wiped out, only Yoda and Ben remained, so the "mystical" view of the Force is what was promulgated in the OT.
The concepts are completely reconcilable to me.
