What I mean by Theology, continues Newman, is none of these things:
“I simply mean the Science of God, or the truths we know about God, put into a system, just as we have a science of the stars and call it astronomy, or of the crust of the earth and call it geology.”
In both these extracts we have the issue clearly set before us: Feeling valid only for the individual is pitted against reason valid universally. The test is a perfectly plain one of fact. Theology based on pure reason must in point of fact convince men universally. If it did not, wherein would its superiority consist? If it only formed sects and schools, even as sentiment and mysticism form them, how would it fulfill its programme of freeing us from personal caprice and waywardness? This perfectly definite practical test of the pretensions of philosophy to found religion on universal reason simplifies my procedure today. I need not discredit philosophy by laborious criticism of its arguments. It will suffice if I show that as a matter of history it fails to prove its pretension to be “objectively” convincing. In fact, philosophy does so fail. It does not banish differences; it founds schools and sects just as feeling does. I believe, in fact, that the logical reason of man operates in this field of divinity exactly as it has always operated in love, or in patriotism, or in politics, or in any other of the wider affairs of life, in which our passions or our mystical intuitions fix our beliefs beforehand. It finds arguments for our conviction, for indeed it has to find them. It amplifies and defines our faith, and dignifies it and lends it words and plausibility. It hardly ever engenders it; it cannot now secure it.290
Lend me your attention while I run through some of the points of the older systematic theology. You find them in both Protestant and Catholic manuals, best of all in the innumerable textbooks published since Pope Leo’s Encyclical recommending the study of Saint Thomas. I glance first at the arguments by which dogmatic theology establishes God’s existence, after that at those by which it establishes his nature.291
The arguments for God’s existence have stood for hundreds of years with the waves of unbelieving criticism breaking against them, never totally discrediting them in the ears of the faithful, but on the whole slowly and surely washing out the mortar from between their joints. If you have a God already whom you believe in, these arguments confirm you. If you are atheistic, they fail to set you right. The proofs are various. The “cosmological” one, so-called, reasons from the contingence of the world to a First Cause which must contain whatever perfections the world itself contains. The “argument from design” reasons, from the fact that Nature’s laws are mathematical, and her parts benevolently adapted to each other, that this cause is both intellectual and benevolent. The “moral argument” is that the moral law presupposes a lawgiver. The “argument ex consensu gentium” is that the belief in God is so widespread as to be grounded in the rational nature of man, and should therefore carry authority with it.
As I just said, I will not discuss these arguments technically. The bare fact that all idealists since Kant have felt entitled either to scout or to neglect them shows that they are not solid enough to serve as religion’s all-sufficient foundation. Absolutely impersonal reasons would be in duty bound to show more general convincingness. Causation is indeed too obscure a principle to bear the weight of the whole structure of theology. As for the argument from design, see how Darwinian ideas have revolutionized it. Conceived as we now conceive them, as so many fortunate escapes from almost limitless processes of destruction, the benevolent adaptations which we find in Nature suggest a deity very different from the one who figured in the earlier versions of the argument.292
The fact is that these arguments do but follow the combined suggestions of the facts and of our feeling. They prove nothing rigorously. They only corroborate our preexistent partialities.
If philosophy can do so little to establish God’s existence, how stands it with her efforts to define his attributes? It is worth while to look at the attempts of systematic theology in this direction.
Since God is First Cause, this science of sciences says, he differs from all his creatures in possessing existence a se. From this “a-se-ity” on God’s part, theology deduces by mere logic most of his other perfections. For instance, he must be both necessary and absolute, cannot not be, and cannot in any way be determined by anything else. This makes Him absolutely unlimited from without, and unlimited also from within; for limitation is non-being; and God is being itself. This unlimitedness makes God infinitely perfect. Moreover, God is One, and Only, for the infinitely perfect can admit no peer. He is Spiritual, for were He composed of physical parts, some other power would have to combine them into the total, and his aseity would thus be contradicted. He is therefore both simple and nonphysical in nature. He is simple metaphysically also, that is to say, his nature and his existence cannot be distinct, as they are in finite substances which share their formal natures with one another, and are individual only in their material aspect. Since God is one and only, his essentia and his esse must be given
