Some things that spring to mind (all are linked):
1. Properly engaging with the ideas of Rupert Sheldrake - accepting the metaphysical value of morphic fields and morphic resonance.
2. Relating morphic fields to the nature and activities of angels.
3. Understanding the relationship between Time and Eternity as set out in Boethius's Consolations of Philosophy. Consequently, understanding the retrospective effects of prayer and the way that prayers for the dead can be conceptualized.
4. Understanding Christianity as the completion of paganism and the reality of animism - especially from considering the medieval universe as set-out by C.S Lewis.
All of the above were helped, behind the scenes, by e-mail interchanges with a new penfriend of 2011 - commenter Kristor.
