If I say that "God exists", this is also not true. He is being beyond being: he is a nothingness beyond being. Therefore St. Augustine says: "The finest thing that we can say of God is to be silent concerning him from the wisdom of inner riches." Be silent therefore, and do not chatter about God, for by chattering about him, you tell lies and commit a sin. If you wish to be perfect and without sin, then do not prattle about God. Also you should not wish to understand anything about God, for God is beyond all understanding. A master says: If I had a God that I could understand, I would not regard him as God. If you understand anything about him, then he is not in it, and by understanding something of him, you fall into ignorance…
