I don't know that we have the discipline to get what I want from this, but let's give it a try ... obtaining some consensus on the 10 topics that occur most often in this forum.
A suggested place to start:
0. Omniscience/omnipotence vs. free will
1. Existence of the spiritual
2. Purpose
3. Fixed references for truth vs. relativism
4. The nature of time and the beginning
5. Discernment of our origin
6. Our ability to extend life vs. inevitability of an end
7. The historicity of Jesus
8. The veracity of the Bible
9. Establishing what we know
