MAN'S CAPACITY FOR GOD

III. THE KNOWLEDGE OF GOD ACCORDING TO THE CHURCH

36 "Our holy mother, the Church, holds and teaches that God, the first principle and last end of all things, can be known with certainty from the created world by the natural light of human reason."11 Without this capacity, man would not be able to welcome God's revelation. Man has this capacity because he is created "in the image of God". 12

37 In the historical conditions in which he finds himself, however, man experiences many difficulties in coming to know God by the light of reason alone:

Though human reason is, strictly speaking, truly capable by its own natural power and light of attaining to a true and certain knowledge of the one personal God, who watches over and controls the world by his providence, and of the natural law written in our hearts by the Creator; yet there are many obstacles which prevent reason from the effective and fruitful use of this inborn faculty. For the truths that concern the relations between God and man wholly transcend the visible order of things, and, if they are translated into human action and influence it, they call for self-surrender and abnegation. The human mind, in its turn, is hampered in the attaining of such truths, not only by the impact of the senses and the imagination, but also by disordered appetites which are the consequences of original sin. So it happens that men in such matters easily persuade themselves that what they would not like to be true is false or at least doubtful.13

38 This is why man stands in need of being enlightened by God's revelation, not only about those things that exceed his understanding, but also "about those religious and moral truths which of themselves are not beyond the grasp of human reason, so that even in the present condition of the human race, they can be known by all men with ease, with firm certainty and with no admixture of error".14

Vatican Council I, Dei Filius 2: DS 3026

If anyone shall have said that the one true God, our Creator and our Lord, cannot be known with certitude by those things which have been made, by the natural light of reason: let him be anathema.

Dei verbum 6

Through divine revelation, God chose to show forth and communicate Himself and the eternal decisions of His will regarding the salvation of men. That is to say, He chose to share with them those divine treasures which totally transcend the understanding of the human mind. (6)

As a sacred synod has affirmed, God, the beginning and end of all things, can be known with certainty from created reality by the light of human reason (see Rom. 1:20); but teaches that it is through His revelation that those religious truths which are by their nature accessible to human reason can be known by all men with ease, with solid certitude and with no trace of error, even in this present state of the human race.

Chapter 2

On revelation

1. The same Holy mother Church holds and teaches that God, the source and end of all things, can be known with certainty from the consideration of created things, by the natural power of human reason : ever since the creation of the world, his invisible nature has been clearly perceived in the things that have been made. [13] 2. It was, however, pleasing to his wisdom and goodness to reveal himself and the eternal laws of his will to the human race by another, and that a supernatural, way. This is how the Apostle puts it : In many and various ways God spoke of old to our fathers by the prophets; but in these last days he has spoken to us by a Son [14].

3. It is indeed thanks to this divine revelation, that those matters concerning God which are not of themselves beyond the scope of human reason, can, even in the present state of the human race, be known by everyone without difficulty, with firm certitude and with no intermingling of error.

4. It is not because of this that one must hold revelation to be absolutely necessary; the reason is that God directed human beings to a supernatural end, that is a sharing in the good things of God that utterly surpasses the understanding of the human mind; indeed eye has not seen, neither has ear heard, nor has it come into our hearts to conceive what things God has prepared for those who love him [15].

5. Now this supernatural revelation, according to the belief of the universal Church, as declared by the sacred Council of Trent, is contained in written books and unwritten traditions, which were received by the apostles from the lips of Christ himself, or came to the apostles by the dictation of the Holy Spirit, and were passed on as it were from hand to hand until they reached us [16].

6. The complete books of the old and the new Testament with all their parts, as they are listed in the decree of the said Council and as they are found in the old Latin Vulgate edition, are to be received as sacred and canonical.

7. These books the Church holds to be sacred and canonical not because she subsequently approved them by her authority after they had been composed by unaided human skill, nor simply because they contain revelation without error, but because, being written under the inspiration of the Holy Spirit, they have God as their author, and were as such committed to the Church.

8. Now since the decree on the interpretation of Holy Scripture, profitably made by the Council of Trent, with the intention of constraining rash speculation, has been wrongly interpreted by some, we renew that decree and declare its meaning to be as follows: that in matters of faith and morals, belonging as they do to the establishing of Christian doctrine, that meaning of Holy Scripture must be held to be the true one, which Holy mother Church held and holds, since it is her right to judge of the true meaning and interpretation of Holy Scripture.

9. In consequence, it is not permissible for anyone to interpret Holy Scripture in a sense contrary to this, or indeed against the unanimous consent of the fathers.

(7) Ibid: Denzinger 1785 and 1786 (3004 and 3005).

12 Cf. Gen 1:27

27 And God created man to his own image: to the image of God he created him: male and female he created them.

13 Pius XII, Humani generis 561: DS 3875

2. It is not surprising that such discord and error should always have existed outside the fold of Christ. For though, absolutely speaking, human reason by its own natural force and light can arrive at a true and certain knowledge of the one personal God, Who by His providence watches over and governs the world, and also of the natural law, which the Creator has written in our hearts, still there are not a few obstacles to prevent reason from making efficient and fruitful use of its natural ability. The truths that have to do with God and the relations between God and men, completely surpass the sensible order and demand self-surrender and self-abnegation in order to be put into practice and to influence practical life. Now the human intellect, in gaining the knowledge of such truths is hampered both by the activity of the senses and the imagination, and by evil passions arising from original sin. Hence men easily persuade themselves in such matters that what they do not wish to believe is false or at least doubtful.

Indeed, it must be attributed to this divine revelation that those things, which in divine things are impenetrable to human reason by itself, can, even in this present condition of the human race, be known readily by all with firm certitude and with no admixture of error. Nevertheless, it is not for this reason that revelation is said to be absolutely necessary, but because God in his infinite goodness has ordained man for a supernatural end, to participation, namely, in the divine goods which altogether surpass the understanding of the human mind, since "eye hath not seen, nor ear heard, neither hath it entered into the heart of man, what things God hath prepared for them that love him" (1 Cor. 2:9; can. 2 and 3).

Dei verbum 6

Through divine revelation, God chose to show forth and communicate Himself and the eternal decisions of His will regarding the salvation of men. That is to say, He chose to share with them those divine treasures which totally transcend the understanding of the human mind. (6)

As a sacred synod has affirmed, God, the beginning and end of all things, can be known with certainty from created reality by the light of human reason (see Rom. 1:20); but teaches that it is through His revelation that those religious truths which are by their nature accessible to human reason can be known by all men with ease, with solid certitude and with no trace of error, even in this present state of the human race.

Thomas Aquinas, Summa Theologiae I, 1, 1

Whether, besides philosophy, any further doctrine is required?

Obj. 1: It seems that, besides philosophical science, we have no need of any further knowledge. For man should not seek to know what is above reason: "Seek not the things that are too high for thee" (Ecclus. 3:22). But whatever is not above reason is fully treated of in philosophical science. Therefore any other knowledge besides philosophical science is superfluous.


Obj. 2: Further, knowledge can be concerned only with being, for nothing can be known, save what is true; and all that is, is true. But everything that is, is treated of in philosophical science---even God Himself; so that there is a part of philosophy called theology, or the divine science, as Aristotle has proved (Metaph. vi). Therefore, besides philosophical science, there is no need of any further knowledge.

On the contrary, It is written (2 Tim. 3:16): "All Scripture, inspired of God is profitable to teach, to reprove, to correct, to instruct in justice." Now Scripture, inspired of God, is no part of philosophical science, which has been built up by human reason. Therefore it is useful that besides philosophical science, there should be other knowledge, i.e. inspired of God.

I answer that, It was necessary for man's salvation that there should be a knowledge revealed by God besides philosophical science built up by human reason. Firstly, indeed, because man is directed to God, as to an end that surpasses the grasp of his reason: "The eye hath not seen, O God, besides Thee, what things Thou hast prepared for them that wait for Thee" (Is. 66:4). But the end must first be known by men who are to direct their thoughts and actions to the end. Hence it was necessary for the salvation of man that certain truths which exceed human reason should be made known to him by divine revelation. Even as regards those truths about God which human reason could have discovered, it was necessary that man should be taught by a divine revelation; because the truth about God such as reason could discover, would only be known by a few, and that after a long time, and with the admixture of many errors. Whereas man's whole salvation, which is in God, depends upon the knowledge of this truth. Therefore, in order that the salvation of men might be brought about more fitly and more surely, it was necessary that they should be taught divine truths by divine revelation. It was therefore necessary that besides philosophical science built up by reason, there should be a sacred science learned through revelation.

Reply Obj. 1: Although those things which are beyond man's knowledge may not be sought for by man through his reason, nevertheless, once they are revealed by God, they must be accepted by faith. Hence the sacred text continues, "For many things are shown to thee above the understanding of man" (Ecclus. 3:25). And in this, the sacred science consists.


Reply Obj. 2: Sciences are differentiated according to the various means through which knowledge is obtained. For the astronomer and the physicist both may prove the same conclusion: that the earth, for instance, is round: the astronomer by means of mathematics (i.e. abstracting from matter), but the physicist by means of matter itself. Hence there is no reason why those things which may be learned from philosophical science, so far as they can be known by natural reason, may not also be taught us by another science so far as they fall within revelation. Hence theology included in sacred doctrine differs in kind from that theology which is part of philosophy.

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.

7. Cf. 1 Kings 16:7; Jer. 17:10.
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.

10 St. Thomas Aquinas, S Th I, 2, 3.

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.
