CHAPTER ONE
MAN'S CAPACITY FOR GOD

II. Ways of Coming to Know God

31 Created in God's image and called to know and love him, the person who seeks God discovers certain ways of coming to know him. These are also called proofs for the existence of God, not in the sense of proofs in the natural sciences, but rather in the sense of "converging and convincing arguments", which allow us to attain certainty about the truth. These "ways" of approaching God from creation have a twofold point of departure: the physical world, and the human person.

32 The world: starting from movement, becoming, contingency, and the world's order and beauty, one can come to a knowledge of God as the origin and the end of the universe.

As St. Paul says of the Gentiles: For what can be known about God is plain to them, because God has shown it to them. Ever since the creation of the world his invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made.7

And St. Augustine issues this challenge: Question the beauty of the earth, question the beauty of the sea, question the beauty of the air distending and diffusing itself, question the beauty of the sky... question all these realities. All respond: "See, we are beautiful." Their beauty is a profession [confessio]. These beauties are subject to change. Who made them if not the Beautiful One [Pulcher] who is not subject to change?8

33 The human person: with his openness to truth and beauty, his sense of moral goodness, his freedom and the voice of his conscience, with his longings for the infinite and for happiness, man questions himself about God's existence. In all this he discerns signs of his spiritual soul. The soul, the "seed of eternity we bear in ourselves, irreducible to the merely material",9 can have its origin only in God.

34 The world, and man, attest that they contain within themselves neither their first principle nor their final end, but rather that they participate in Being itself, which alone is without origin or end. Thus, in different ways, man can come to know that there exists a reality which is the first cause and final end of all things, a reality "that everyone calls God".10

35 Man's faculties make him capable of coming to a knowledge of the existence of a personal God. But for man to be able to enter into real intimacy with him, God willed both to reveal himself to man, and to give him the grace of being able to welcome this revelation in faith.(so) the proofs of God's existence, however, can predispose one to faith and help one to see that faith is not opposed to reason.

Rom 1:19-20

19 Because that which is known of God is manifest in them. For God hath manifested it unto them. 20 For the invisible things of him, from the creation of the world, are clearly seen, being understood by the things that are made; his eternal power also, and divinity: so that they are inexcusable.

Acts 14:15,17

14 And saying: Ye men, why do ye these things? We also are mortals, men like unto you, preaching to you to be converted from these vain things, to the living God, who made the heaven, and the earth, and the sea, and all things that are in them: 15 Who in times past suffered all nations to walk in their own ways.

16 Nevertheless he left not himself without testimony, doing good from heaven, giving rains and fruitful seasons, filling our hearts with food and gladness. (numbering in Douay Rheims is different) 17 And speaking these things, they scarce restrained the people from sacrificing to them.

Acts 17:27-28

27 That they should seek God, if happily they may feel after him or find him, although he be not far from every one of us: 28 For in him we live, and move, and are; as some also of your own poets said: 'For we are also his offspring.'

Wisdom 13:1-9

1 But all men are vain, in whom there is not the knowledge of God: and who by these good things that are seen, could not understand him that is, neither by attending to the works have acknowledged who was the workman: 2 But have imagined either the fire, or the wind, or the swift air, or the circle of the stars, or the great water, or the sun and moon, to be the gods that rule the world. 3 With whose beauty, if they, being delighted, took them to be gods: let them know how much the Lord of them is more beautiful than they: for the first author of beauty made all those things. 4 Or if they admired their power and their effects, let them understand by them, that he that made them, is mightier than they: 5 For by the greatness of the beauty, and of the creature, the creator of them may be seen, so as to be known thereby.

6 But yet as to these they are less to be blamed. For they perhaps err, seeking God, and desirous to find him. 7 For being conversant among his works, they search: and they are persuaded that the things are good which are seen. 8 But then again they are not to be pardoned. 9 For if they were able to know so much as to make a judgment of the world: how did they not more easily find out the Lord thereof?

8 St. Augustine, Sermo 241, 2: PL 38, 1134,
The beauty of the unchangeable creator is to be inferred from the beauty of the
changeable creation 

"Question the beauty of the earth, question the beauty of the sea, question the beauty of the air, amply spread around everywhere, question the beauty of the sky, question the serried ranks of the stars, question the sun making the day glorious with its bright beams, question the moon tempering the darkness of the following night with its shining rays, question the animals that move in the waters, that amble about on dry land, that fly in the air; their souls hidden, their bodies evident; the visible bodies needing to be controlled, the invisible souls controlling them; question all these things. They all answer you, 'Here we are, look; we're beautiful.'

Their beauty is their confession. Who made these beautiful changeable things, if not one who is beautiful and unchangeable? Finally in man himself, in order to be able to understand and know God, the creator of the universe; in man himself, I repeat, they questioned these two elements, body and soul. They questioned the very thing they themselves carried around with them; they could see their bodies, they couldn't
see their souls. But they could only see the body from the soul. I mean, they saw with their eyes, but inside there was someone looking out through these windows. Finally, when the occupant departs, the house lies still; when the controller departs, what was being controlled falls down; and because it falls down, it's called a cadaver, a corpse. Aren't the eyes complete in it? Even if they're open, they see nothing. There are ears there, but the hearer has moved on; the instrument of the tongue remains, but the musician who used to play it has withdrawn.

So they questioned these two things, the body which can be seen, the soul which cannot be seen, and they found that what cannot be seen is better than what can be seen; that the hidden soul is better, the evident flesh of less worth. They saw these two things, they observed them, carefully examined each one, and they found that each, in man himself, is changeable. The body is changeable by the processes of age, of decay, of nourishment, of health improving and deteriorating, of life, of death. They passed on to the soul, which they certainly grasped as being better, and also admired as invisible. And they found that it too is changeable; now willing, now not willing; now knowing, now not knowing; now remembering, now forgetting; now frightened, now brave; now advancing toward wisdom, now falling back into folly. They saw that it too is changeable. They passed on beyond even the soul; they were looking, you see, for something unchangeable. So in this way they arrived at a knowledge of the god who made things, through the things which he made."

9 GS 18 # 1; cf. 14 # 2.

Gaudium et spes 18 § 1

It is in the face of death that the riddle a human existence grows most acute. Not only is man tormented by pain and by the advancing deterioration of his body, but even more so by a dread of perpetual extinction. He rightly follows the intuition of his heart when he abhors and repudiates the utter ruin and total disappearance of his own person. He rebels against death because he bears in himself an eternal seed which cannot be reduced to sheer matter. All the endeavors of technology, though useful in the extreme, cannot calm his anxiety; for prolongation of biological life is unable to satisfy that desire for higher life which is inescapably lodged in his breast.

Gaudium et spes 14 § 2

Now, man is not wrong when he regards himself as superior to bodily concerns, and as more than a speck of nature or a nameless constituent of the city of man. For by his interior qualities he outstrips the whole sum of mere things. He plunges into the depths of reality whenever he enters into his own heart; God, Who probes the heart,(7) awaits him there; there he discerns his proper destiny beneath the eyes of God. Thus, when he recognizes in himself a spiritual and immortal soul, he is not being mocked by a fantasy born only of physical or social influences, but is rather laying hold of the proper truth of the matter.

1 Kings 16:7

      7 And the Lord said to Samuel: Look not on his countenance, nor on the height of his stature: because I have rejected him, nor do I judge according to the look of
man: for man seeth those things that appear, but the Lord beholdeth the heart.

Jer. 17:10

      10 I am the Lord who search the heart and prove the reins: who give to every one according to his way, and according to the fruit of his devices.

Whether God exists?

Obj. 1: It seems that God does not exist; because if one of two contraries be infinite, the other would be altogether destroyed. But the word "God" means that He is infinite goodness. If, therefore, God existed, there would be no evil discoverable; but there is evil in the world. Therefore God does not exist.

Obj. 2: Further, it is superfluous to suppose that what can be accounted for by a few principles has been produced by many. But it seems that everything we see in the world can be accounted for by other principles, supposing God did not exist. For all natural things can be reduced to one principle which is nature; and all voluntary things can be reduced to one principle which is human reason, or will. Therefore
there is no need to suppose God's existence.

On the contrary, It is said in the person of God: "I am Who am." (Ex. 3:14)

I answer that, The existence of God can be proved in five ways.

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.

The second way is from the nature of the efficient cause. In the world of sense we find there is an order of efficient causes. There is no case known (neither is it, indeed, possible) in which a thing is found to be the efficient cause of itself; for so it would be prior to itself, which is impossible. Now in efficient causes it is not possible to go on to infinity, because in all efficient causes following in order, the first is the cause of the intermediate cause, and the intermediate is the cause of the ultimate cause, whether the intermediate cause be several, or only one. Now to take away the cause is to take away the effect. Therefore, if there be no first cause among efficient causes, there will be no ultimate, nor any intermediate cause. But if in efficient causes it is possible to go on to infinity, there will be no first efficient cause, neither will there be an ultimate effect, nor any intermediate efficient causes; all of which is plainly false. Therefore it is necessary to admit a first efficient cause, to which everyone gives the name of God.

The third way is taken from possibility and necessity, and runs thus. We find in nature things that are possible to be and not to be, since they are found to be generated, and to corrupt, and consequently, they are possible to be and not to be. But it is impossible for these always to exist, for that which is possible not to be at some time is not. Therefore, if everything is possible not to be, then at one time there could have been nothing in existence. Now if this were true, even now there would be nothing in existence, because that which does not exist only begins to exist by something already existing. Therefore, if at one time nothing was in existence, it would have been impossible for anything to have begun to exist; and thus even now nothing would be in existence---which is absurd. Therefore, not all beings are merely possible, but there must exist something the existence of which is necessary. But every necessary thing either has its necessity caused by another, or not. Now it is impossible to go on to infinity in necessary things which have their necessity caused by another, as has been already proved in regard to efficient causes. Therefore we cannot but postulate the existence of some being having of itself its own necessity, and not receiving it from another, but rather causing in others their necessity. This all men speak of as God.

The fourth way is taken from the gradation to be found in things. Among beings there are some more and some less good, true, noble and the like. But "more" and "less" are predicated of different things, according as they resemble in their different ways something which is the maximum, as a thing is said to be hotter according as it more nearly resembles that which is hottest; so that there is something which is truest, something best, something noblest and, consequently, something which is uttermost being; for those things that are greatest in truth are greatest in being, as it is written in Metaph. ii. Now the maximum in any genus is the cause of all in that genus; as fire, which is the maximum heat, is the cause of all hot things. Therefore there must also be something which is to all beings the cause of their being, goodness, and every other perfection; and this we call God.

The fifth way is taken from the governance of the world. We see that things which lack intelligence, such as natural bodies, act for an end, and this is evident from their acting always, or nearly always, in the same way, so as to obtain the best result. Hence it is plain that not fortuitously, but designedly, do they achieve their end. Now whatever lacks intelligence cannot move towards an end, unless it be directed by some being endowed with knowledge and intelligence; as the arrow is shot to its mark by the archer. Therefore some intelligent being exists by whom all natural things are directed to their end; and this being we call God.

Reply Obj. 1: As Augustine says (Enchiridion xi): "Since God is the highest good, He would not allow any evil to exist in His works, unless His omnipotence and goodness were such as to bring good even out of evil." This is part of the infinite goodness of God, that He should allow evil to exist, and out of it produce good.

Reply Obj. 2: Since nature works for a determinate end under the direction of a higher agent, whatever is done by nature must needs be traced back to God, as to its first cause. So also whatever is done voluntarily must also be traced back to some higher cause other than human reason or will, since these can change or fail; for all things that are changeable and capable of defect must be traced back to an immovable and self-necessary first principle, as was shown in the body of the Article.
