Richard Dawkins, the prototypical neo-atheist, shows that God doesn't exist as substance. He seems to have forgotten Aristotle's explanation that there are several ways of being, of which substance is only one. God certainly exists as form. The form is thoroughly documented in the sacred texts of the world's religions. But, Dawkins objects, the form refers to nothing that can be empirically observed. Well, yes, Professor Dawkins, there is no substance that corresponds to the form, because, as Aquinas could have told you, God is not a material substance.
When the atheist says, "God exists only in your mind, not in reality," he sees this as a problem with God, rather than a problem with reality. But if God doesn't exist in reality, this can only be because we ignore the message of His prophets. We use piety one day a week to adorn merciless greed on the other six. We have given up trying to mold ourselves into the form of God and settled for ourselves as we are. Greedy. Selfish. Merciless to the poor and oppressed.
We have ceased trying to be perfect as our heavenly Father is perfect. We have closed not only the Bible, but also Plato, the Pali Canon, and all the great books that once taught us about God and prayer. Now we fill our leisure with television, and then claim we have no time for God.
To come to know God is to come to know and perfect your own conception of the good. With every passing year, more and more false prophets preach from their Madison Avenue pulpits, "The good is pleasure! The logos is Wall Street! The market is God!" We bow and say, "Yes, teacher, teach us about the good." Then we take pilgrimages to Disneyland and Rodeo Drive to visit the temples of consumption and offer our reverence and devotion to the market god.
In his first letter, Peter tells his parishioners to rid themselves of all malice and deceit. He tells them to stop gossiping about the faults of their neighbors. Leave your adult self behind, he says. Become like a newborn babe. Suckle on pure spiritual milk as you grow up again.
I must go back to infancy and begin my education all over. I must deliberately forget the trash Hollywood and Madison Avenue have dinned into my mind. I must replace it with pure spiritual milk from saints and sages. The spoiled milk of false prophets whose true goal is not my salvation, but their profit, has been making me seriously ill.
Rid yourselves of malice, deceit, hypocrisy, envy, and slander of every kind. Like newborn babes, crave pure spiritual milk, so that by it you may grow up in your salvation, now that you have tasted that the Lord is good.
1 Peter 2:1-2
But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ. I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready, for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way?
1 Corinthians 3:1-3
God is the most noble of beings. Now it is impossible for a body to be the most noble of beings; for a body must be either animate or inanimate; and an animate body is manifestly nobler than any inanimate body. But an animate body is not animate precisely as body; otherwise all bodies would be animate. Therefore its animation depends upon some other thing, as our body depends for its animation on the soul. Hence that by which a body becomes animated must be nobler than the body. Therefore it is impossible that God should be a body.
