If you begin your question as “What is God?”, you are without hope of an answer. Either God is ineffable, or God is that which causes some phenomenon. Of course if we ask “What is the cause of this phenomenon?”, we know we haven’t leant anything about God, only stated that some phenomenon has a cause and that we’ll call that cause “God”. Too, there’s nothing to be said about the ineffable but that by definition, it’s, well, ineffable.
But if you instead begin your question as “Who am I?”, the mystery is close at hand. God becomes the darkness, the unknown, that which will become illuminated in time. For whatever else God is that is beyond us, God is not beyond the inexhaustible image we may bear of him in our own humanity. God is then synonymous with our humanity.
The revelation of God is then the revelation of humanity; ongoing, developing, a discovery of participation. It isn’t contingent to scripture, though scripture may point us to various ways to think of God, of ourselves. It isn’t contingent to nature, though we cannot understand ourselves aside from circumstance. It is however, contingent to humanity as all things are considered from this perspective and all things true are all things which eventually must make sense. Since God is not the nature He effects, nor is He bound as pages or lengths of scroll, nature and scripture are backdrops for that which makes sense. That which makes sense is entirely from human sensibility about himself and the world.
The revelation of God then, if it makes sense at all, is a revelation about humanity and only insomuch as it is a reflection of God.
The question of God’s existence and of God’s nature become irrelevant. Humanity exists and is synonymous with our conceptions of God. When we speak of God’s nature, we’re functionally speaking of our own. The Atheist isn’t wrong to say the Theist personifies. The Theist isn’t wrong to say we can know God. Either type of person is speaking about humanity. The Atheist would only be wrong in thinking that because of personification, God doesn’t exist or that personification isn’t a revelation. The Theist would only be wrong in thinking that what is revealed is the ineffable God himself rather than what He wishes us to learn from this looking “glass, darkly” of humanity, given our circumstance and our past ideas previously penned. Each is then free to choose whichever language he prefers in speaking to his own humanity.
Just a thought.
