Theology is the attempt to communicate articulate
statements about
God. For our purposes,
God is
infinite and not one element within a larger system.
The problem with theology is that it attempts to leap two infinitely wide bridges. Since the human mind is finite and God is infinite, we can never really create an accurate concept of God. And since words are an extremely inaccurate way to communicate concepts, what we communicate is only a rough approximation of what we think. As a result, theologians are supposed to keep in mind that their efforts aren't getting at the truth about God in the same way that physicists are getting at the truth about elements of the physical universe.
What theology can do is provide a continuing translation of the underlying principles of a religion into terms that communicate to the people of a given time and place. Most (but not all) of the critiques of religion on Everything are really attacks on bad theology (which has its own node).
