Pints With Aquinas

If you could sit down with St. Thomas Aquinas over a pint of beer and ask him any one question, what would it be? Every episode of Pints With Aquinas revolves around a question, a question that St. Thomas addresses in his most famous work, The Summa Theologica. So get your geek on, pull up a bar stool, and grab a cold one. Here we go!

[Muhammad] seduced the people by promises of carnal pleasure to which the concupiscence of the flesh goads us. His teaching also contained precepts that were in conformity with his promises, and he gave free rein to carnal pleasure. In all this, as is not unexpected, he was obeyed by carnal men. As for proofs of the truth of his doctrine, he brought forward only such as could be grasped by the natural ability of anyone with a very modest wisdom. Indeed, the truths that he taught he mingled with many fables and with doctrines of the greatest falsity. He did not bring forth any signs produced in a supernatural way, which alone fittingly gives witness to divine inspiration; for a visible action that can be only divine reveals an invisibly inspired teacher of truth. On the contrary, Muhammad said that he was sent in the power of his arms—which are signs not lacking even to robbers and tyrants. What is more, no wise men, men trained in things divine and human, believed in him from the beginning, Those who believed in him were brutal men and desert wanderers, utterly ignorant of all divine teaching, through whose numbers Muhammad forced others to become his followers by the violence of his arms. Nor do divine pronouncements on the part of preceding prophets offer him any witness. On the contrary, he perverts almost all the testimonies of the Old and New Testaments by making them into fabrications of his own, as can be. seen by anyone who examines his law. It was, therefore, a shrewd decision on his part to forbid his followers to read the Old and New Testaments, lest these books convict him of falsity. It is thus clear that those who place any faith in his words believe foolishly

St Thomas Aquinas, in the first part of his Summa Theologica, after having enumerated five proofs for the existence of God, proceeds to outline and explicate his attributes, of which Thomas says He has eight:

1) Simplicity, 2) perfection, 3) goodness, 4) infinity, 5) ubiquity, 6) immutability, 7) eternity, and 8) unity.

This is the order in which he deals with them and I thought I would provide a quick summary of each in the same order for those that are interested.

To read what Thomas himself says, start here in the Summa.

The Simplicity of God means that God has no parts, that He is not composed in any way. He is not, as we are, the composition of body and soul, nor is He the composition of essence and existence. One of Thomas’ arguments for why God is not a composition of body and soul is the following: 1. Bodies, by necessity, move. 2. God is the unmoved mover. 3. Therefore God does not have a body (this may be the quickest refutation of Mormonism ever!). Nor is God a composition of essence (what a thing is) and existence (that a thing is). Rather, in God, essence and existence are the same thing. We see Biblical evidence of this in the book of Exodus where God responds to Moses’ request for a name, “I am who I am” (3:14). If essence and existence were not the same in God, if what he was was not the same thing as that he was, then there would exist outside of God the reason for his existence, which is absurd.


The perfection of God means that God lacks nothing. He is the the fullness of being. As St. Thomas says, “to be the first principle for others it is necessary to be maximally in act, and as such the most perfect being.” The more a being is like God, the more perfect it is. The fact that we can even say that one being is more perfect than another implies a most perfect being, and this, of course, is the crux of Thomas’ fourth proof for the existence of God.

God, who is the greatest conceivable being, is also goodness itself, since being and goodness are really convertible. A being, in so far as it is like God, is good, and a being, in so far as it is unlike God, is not. Given that all creation is ordered to this good, one might reasonably ask, “If all creation is ordered toward the supreme good, who is God, to what good may we say that God is ordered? To none other than the supreme good who is himself. The only appropriate finality for an infinite being is infinite being.”

The infinity of God refers to the fact that God is in no way limited. He is Subsistent being itself. “God is,” in the words of D.Q. McInerny, “without limits because He is Himself the inexhaustible source of all the riches of being. 

The ubiquity of God means that God is everywhere. Not that God has a body and is “in” each and every place—God is not inside of my glass of milk in the sense that he has extension in space. Rather, what we mean when we say God is everywhere—including my glass of milk—is this: “wherever something is operating, there it is.” Since God is operating everywhere, he is everywhere. The sentiment “God is closer to you than you are to yourself,” is not just a feel-good sentiment, it’s true.

The sixth attribute put forward by Aquinas is His immutability, that is, his unchangeableness. If a thing changes it changes for better or for worse. If God was mutable, therefore, his changing would make him better or worse. If it made him better then he wasn’t perfect to begin with. If it made him worse, then he isn’t perfect now.

The philosopher Boethius, in The Consolation of Philosophy defines eternity thusly: “Eternity is the everlasting, totally simultaneous and perfect possession of life.” And this is the definition St. Thomas adopts when speaking of God’s eternity. God is eternal because he immutable. “If we are right in describing time as the measure of motion,” writes, McInerny, “we are equally right in describing eternity as the measure of permanence.”

Unity, like goodness, and beauty, is a transcendental of being. It is because God is being that he issimple that he is perfect unity. St. Thomas writes, “that which is simple, is undivided both with respect to act and potency.” And since it is not possible to divide God in any way (matter/form; essence/existence, etc.), then it follows that God is perfect in unity.

The first and more manifest way is the argument from motion. It is certain, and evident to our senses, that in the world some things are in motion. Now whatever is in motion is put in motion by another, for nothing can be in motion except it is in potentiality to that towards which it is in motion; whereas a thing moves inasmuch as it is in act. For motion is nothing else than the reduction of something from potentiality to actuality.

But nothing can be reduced from potentiality to actuality, except by something in a state of actuality. Thus that which is actually hot, as fire, makes wood, which is potentially hot, to be actually hot, and thereby moves and changes it. Now it is not possible that the same thing should be at once in actuality and potentiality in the same respect, but only in different respects. For what is actually hot cannot simultaneously be potentially hot; but it is simultaneously potentially cold.

It is therefore impossible that in the same respect and in the same way a thing should be both mover and moved, i.e. that it should move itself. Therefore, whatever is in motion must be put in motion by another. If that by which it is put in motion be itself put in motion, then this also must needs be put in motion by another, and that by another again. But this cannot go on to infinity, because then there would be no first mover, and, consequently, no other mover; seeing that subsequent movers move only inasmuch as they are put in motion by the first mover; as the staff moves only because it is put in motion by the hand.

Therefore it is necessary to arrive at a first mover, put in motion by no other; and this everyone understands to be God.
