I'm in agreement with ITJock in that there are fundemental truths to many major religions, and many minor ones too, I'd guess.
"Considering the marvelous complexity of our universe, its clockwork perfection, its balances of this against that -- matter, energy, gravitation, time, dimension, I believe that ... what we are goes beyond Euclidean or other "practical" measuring systems, and that our existence is part of a reality beyond what we understand now as reality."
When I was a child in Lutheran school (yes, they have those), I asked a teacher to explain the seeming One-God/Holy-Trinity disparity. Her reply was that there are some things we just can't understand and must accept on faith. I thought that a cop-out answer at the time. If you can't concieve it, how can you justify accepting it?
But I've had some time to reflect. I've truly come to believe that no organized religion, major or minor, has hit on The One Truth. It's too complex, or perhaps too evasively simple, and we're not evolved enough to grasp it. So the people who are truly at one with God or Nature or The Universe are those whose understanding is at its most basic, its most simplistic. Harmony. Love. Balance. Understanding.
So I'm an agnostic, which is literally transalted as: I dont know.
