I think this is a better analogy than the egg.
I find it odd that everyone always says the trinity is so hard to understand
I probably think too much (mrs. malakhi certainly thinks so! ;o)
The hard thing for me to make sense of is the idea of it being three separate persons. If the theological language spoke of the Word and the Spirit as being manifestations or facets or functions or emanations of the Divine Being, that would make more sense to me. To me, saying that God is three "persons" implies that God has three distinct personalities. That is what I can't grasp.
There also is the question of the nature of the incarnation. I know you don't want to get into a debate on this, and I assure you I'm not starting one. I'm interested, rather, in getting your opinion. The theological formulation is that Jesus was one person with two natures, a divine and a human nature. Do you have an analogy (like the sun or the egg) which says something about how you understand the incarnation? Was the human person Jesus filled with the "Son" in any way similar to the way believers are filled with the "Spirit"? How closely joined were the human and divine in him? Do you think he was always conscious of his divine nature? Again, this is not to debate, just to get your thoughts. If you want to answer me privately, that is fine.
