As we continue a discourse regarding the Light and the Darkness, we should not confuse the concept with Good and Evil. “The Light” represents God, and specifically the transcendent Godhead itself, which is pure existence and truth. “The Darkness” represents the power of non-existence, a force outside of God’s creation. Nothing is outside of God’s creation, and the Darkness is that nothingness.
Now, it’s entirely possible (in fact likely) that Good and Evil are cosmic forces which transcend humanity — but as humans I don’t think it’s possible for us to understand it in that context. In most conversations we have, “good” and “evil” are posited in relation to our existence, limited by our perception. From this point of view, the Darkness are inherently evil , in that they seek only destruction, and they oppose the will of God. But it is an evil based on their being alien to our world view. In fact, they are beyond our human morality, and it is that which makes them appear to be evil.
But the same is true of God, isn’t it? God exists beyond human morality, and so often appears to “evil” by human standards (hence, theodicy). We cannot understand God anymore than we can understand the Darkness. In deed, there are many things which are infinitely smaller than these cosmic beings, which we cannot understand because they are larger than we are. Hurricanes may occur to us as evil, for example. And these are the manners in which God is evil. But when we try (though we must fail) to understand these things on a cosmic scale, we can at least affirm that God is ultimately creative, and the Darkness ultimately destructive. God is the essence (the platonic Form) of Truth, and while truth is sometimes incidentally evil, it is ultimately good. The Darkness, on the contrary, is the essence of nonexistence, and so ultimately evil.
Beyond these two completely different forms of evil (the alien evil of the Darkness and the incidental evil of the Light), there is a third form of evil in the case of demons and evil gods. These are the only forces which are actively and deliberately evil, what we might call “malevolent”. As we read in the Book of Job, Satan himself sits on God’s court and takes his orders. This is the form of evil which is actually part of God’s plan. Where the Darkness seeks our destruction, and the Light seeks a Higher Good (which may seem evil to us), this form of evil is involved with our corruption and temptation. God exists beyond dualities, but he has set up, for us, a dualistic universe. And so there are evil forces which “work for” Him. They have their role to play. Death, for example, is an important part of Life. This interplay of “Good” and “Evil” forces which serve the overall good of the universe should not be confused with the pure destructive evil of the Darkness.
