Reality is not simple, therefore our understanding of Reality must not be simple or linear.
God is not Simple or legalistic. God is Trinity and holistic.
Life is not simple or linear as evolution would have it be. Life is interactive and holistic as ecology is.
Music is interactive, changing, and holistic as is life and history. Much of scripture is poetry, and Hebrew is a poetic language. Jesus taught in stories and metaphors, poetic language even in the Greek. Paul translated these Hebrew images into Greek thought without the philosophy.
The Trinity has caught the complex/one Reality of both God, humans created in God's Image, and God's Creation.
