In the Tenth Article We Ask: IS IT NECESSARY FOR MAN TO HAVE FAITH?
Difficulties:
It seems that it is not, for
1. As is said in Deuteronomy (32:4): "The works of God are perfect." But nothing is perfect unless it is provided with those things which it must have to attain its proper end. Therefore, sufficient means to attain its final end are given to each thing when God creates its nature. But matters of faith are beyond the knowledge which belongs to men by reason of the constitution of their nature. Therefore, to reach his end man does not need faith, through which these things are perceived or known.
2. It was said that by reason of the constitution of his nature man receives those things which are necessary to reach his natural end, such as the happiness of life of which the philosophers speak, but does not receive the things needed to reach the supernatural end, which is everlasting happiness.--On the contrary, man, because of his essential constitution, is made to be a sharer of eternal happiness. It was for this that God created a rational nature which could know Him, as we see in the Sentences. Therefore, the principles through which he can reach that end should be innate in man's very nature.
3. We have to have activity as well as knowledge to reach our end. But the habits of virtue given us to attain our supernatural end do not give us an ordination to works other than those toward which we are ordered by natural reason, but, rather, to a more perfect performance of those same works. For acquired and infused chastity seem to have the same act, namely, to control venereal pleasure. Therefore, to reach a supernatural end we do not need the infusion of a cognitive habit ordained to knowledge of something besides what we naturally know, but only to a more perfect knowledge of these same natural objects. Hence, it seems that to have faith in things which are not evident to reason would not be necessary for salvation.
4. A power has no need of a habit for that to which it has a natural determination, as is evident in irrational powers, as the nutritive and the generative, which carry on their activity without the mediation of a habit. Now, the human understanding is naturally directed to knowledge of God. Therefore, it does not need a habit to lead it to this knowledge.
5. That which can reach its final end by itself is more perfect than that which cannot do so. But brute animals can attain their ends by means of natural principles. Therefore, since man is more perfect than they, it seems that natural knowledge should be enough for him to reach his end. Thus, he does not need faith.
6. What is considered to be a vice does not seem necessary for salvation. But credulity is considered to be a vice. Thus, in Ecclesiasticus (19:4) we read: "He that is hasty to give credit is light of heart." Therefore, belief is not necessary for salvation.
7. Since God must be believed above all else, our belief should be greater in one through whom it is clearer that God is speaking. But it is clearer that God has spoken through the natural instinct of reason than through any prophet or apostle, since by this it is most certain that God is the author of all nature. Therefore, we should hold more firmly the things which reason proposes than those which the prophets and apostles preach, and which are the objects of faith. Therefore, since these latter sometimes seem to conflict with what natural reason dictates, as when they say that God is three and one, or that a virgin conceived, and so on, it does not seem reasonable to put faith in such things.
8. That which is rendered useless by the arrival of another thing does not seem to be needed for that thing. For it would not become useless unless there were some opposition between it and the other. Now, a thing does not incline toward its opposite; rather, it withdraws from it. But faith becomes useless when glory arrives. Therefore, faith is not necessary to obtain glory.
9. Nothing in order to reach its end needs that which destroys it. But faith destroys reason, for, as Gregory says: "Faith deserves no merit when human reason offers it proof." Therefore, reason does not need faith to reach its end.
10. A heretic does not have the habit of faith. But, sometimes, a heretic believes in certain truths which are beyond the reach of reason. Thus, he may believe that the Son of God was made flesh, although he does not believe that He suffered. Therefore, the habit of faith is not needed to know things which are above reason.
11. When something is proved by means of many middle terms, the whole proof is ineffective if one of the middle terms is weak. This is evident in syllogistic deductions, where the existence of one false or doubtful proposition makes the whole proof ineffectual. But the truths of faith reach us through many intermediaries. For God told them to the apostles or prophets, who related them to their followers. These men in turn told others, and in this way they finally reached us through various intermediaries. Now, it is not certain that there was infallible truth in all of these intermediaries. For, since they were men, they could deceive and be deceived. Therefore, we can have no certainty about matters of faith, and so it seems foolish to assent to them.
12. That in a work which lessens the merit for eternal life does not seem necessary to obtain eternal life. But, since difficulty makes for merit, habit, which brings facility, lessens merit. Therefore, the habit of faith is not necessary for salvation.
13. The powers of reason are more noble than the powers of physical nature. But physical powers do not need habits for their acts. Therefore, understanding does not need the habit of faith for its acts.
To the Contrary:
1'. In Hebrews (11:6) we read: "But without faith it is impossible to please God."
2'. That without which man is damned is necessary for salvation. But faith is so needed, as appears in Mark (16:16): "He that believeth not shall be condemned." Therefore, faith is necessary for salvation.
3'. A higher life needs a higher knowledge. But the life of grace is higher than the life of nature. Therefore, it needs some supernatural knowledge, which is the knowledge of faith.
REPLY:
To obtain eternal life it is necessary to have faith in those things which are beyond the grasp of reason. We can understand this from what follows. For a thing is brought from imperfection to perfection only through the activity of something perfect. Nor does the imperfect thing at once in the very beginning fully receive the action of that which is perfect; at first it receives it imperfectly and, later, more perfectly. And it continues in this way until it reaches perfection. This is evident in all physical things, which acquire a perfection gradually.
We see the same thing in human works, especially in the learning process. For in the beginning a man has incomplete knowledge, and, if he is to reach the perfection of scientific knowledge, needs an instructor to bring him to that perfection. Nor could the teacher do this unless he himself had full knowledge of the science, that is unless he understood the intelligible principles of the things which form the subject matter of the science. At the outset of his teaching, however, he does not explain to his pupil the intelligible principles of the things to be known which he intends to teach, because then, at the very beginning, the pupil would [have to] know the science perfectly. Instead, the teacher proposes some things, the principles of which the pupil does not understand when first taught, but will know later when he has made some progress in the science. For this reason it is said that the learner must believe. And he could not acquire mastery of the science in any other way unless he accepted without proof those things which he is taught at first and the arguments for which he cannot then understand.
The final perfection toward which man is ordained consists in the perfect knowledge of God, which, indeed, man can reach only if God, who knows Himself perfectly, undertakes to teach him. Early in his life, however, man is not capable of receiving perfect knowledge. So, he has to accept certain things on faith and by means of these he is led on till he arrives at perfect knowledge.
Now, some of these things are such that they can never be perfectly known in this life, for they wholly transcend the power of human reason. These we must believe as long as we are in this life. However, we shall see them perfectly in heaven.
There are others which we can know perfectly in this life, as, for instance, the things which we can prove conclusively about God. Still, in the beginning, we have to believe these for five reasons, which Rabbi Moses gives. The first reason is the depth and subtlety of these objects of knowledge which are farthest removed from the senses. Hence, at the very beginning, man is not qualified to know them perfectly. The second reason is the weakness of human understanding when it begins to operate. The third is the number of things needed for a conclusive proof of these. And a man can learn them all only after a long time. The fourth reason is the disinclination for scientific investigation which some men have because they lack the proper temperament. The fifth is the need of engaging in other occupations to provide the necessities of life.
From all this it is clear that, if it were necessary to use a strict demonstration as the only way to reach a knowledge of the things which we must know about God, very few could ever construct such a demonstration and even these could do it only after a long time. From this it is evident that the provision of the way of faith, which gives all easy access to salvation at any time, is beneficial to man.
Answers to Difficulties:
1. In the constitution of man's nature full provision is made for him, in so far as, to attain the end which is within the power of nature, he is given principles which are capable of causing that end. However, for the end which is beyond his natural ability man is given principles which are not a cause of the end, but which give him a capacity for those things which do bring him to his end. For this reason Augustine says: "The capacity to have faith and charity is due to man's nature, but their actual possession is due to the grace which the faithful receive."
2. In the very beginning of creation, human nature was ordained to beatitude, not as to an end proper to man by reason of his nature, but given him solely by divine liberality. Therefore, there is no need for the principles of nature to have sufficient power to achieve that end without the aid of special gifts with which God in His generosity supplements them.
3. One who is some distance from an end can know the end and desire it; however, he cannot engage in activity which directly concerns the end, but only in that which is connected with the means to the end. Therefore, if we are to reach our supernatural end, we need faith in this life to know the end, for natural knowledge does not go that far. But our natural powers do extend to the means to the end, although not precisely as ordained to that end. Therefore, we do not need infused habits for any other activity than that which natural reason dictates, but just for a more perfect performance of the same activity. However, this is not the case with knowledge for the reason given above.*
4. Our understanding does not have a natural determination to matters of faith in the sense that it should know them naturally, but it does in some sense have a natural ordination to a knowledge of them in so far as nature is said to have an ordination to grace by reason of a divine decree. Consequently, this does not remove the need we have for the habit of faith.
5. Man is more perfect than the other animals. However, nature does not determine what is necessary for him to reach his end as it does for other animals, and this for two reasons. First, since man is ordained to a higher end, therefore, even though he needs more helps to reach that end and natural principles are not enough for him, he is nonetheless more perfect. Second, the very fact that he can have many ways to reach his end is a perfection in man. For this reason he cannot be limited to one natural way as other animals are. But, instead of all the means which nature provides for other animals, man is given reason, through which he can take care of the necessities of this life and make himself fit to receive the divine helps for the future life.
6. Credulity is called a vice because it means an excess of belief, just as to be a drinker means an excess in drinking. However, one who believes God does not believe immoderately, because we cannot put too much faith in Him. So, the conclusion does not follow.
7. The apostles and prophets under divine inspiration have never said anything contrary to the dictates of natural reason. Nevertheless, they have said things which are beyond the comprehension of reason, and so to this extent seem to contradict reason, although they do not really oppose it. In a similar way, to an unlettered person it seems contrary to reason to say that the sun is larger than the earth and the diagonal is incommensurable with the side. However, these appear reasonable to those who are educated.
8. It is because of its imperfection that faith is rendered useless when glory arrives. And on this account it has a certain opposition to the perfection of glory. But, as far as the knowledge of faith is concerned, faith is necessary for salvation. For there is nothing unreasonable in the fact that something imperfect, which is directed to the perfection of the end, ceases to exist when the end is reached, as motion ceases to be when rest, which is its end, is reached.
9. Faith does not destroy reason, but goes beyond it and perfects it, as has been said above.
10. A heretic does not have the habit of faith even if it is only one article of faith which he refuses to believe. For infused habits are lost through one contrary act. And the habit of faith has this power, that through it the understanding of the believer is withheld from giving assent to things contrary to faith, just as chastity restrains us from acts opposed to chastity. Now, when a heretic believes something which is beyond the scope of natural knowledge, he does this not by reason of an infused habit, for such a habit would direct him equally to all objects of belief, but by reason of some human judgment, as happens also with pagans who believe certain things surpassing nature about God.
11. All the intermediaries through which faith comes to us are above suspicion. We believe the prophets and apostles because the Lord has been their witness by performing miracles, as Mark (16:20) says: ". . . and confirming the word with signs that followed." And we believe the successors of the apostles and prophets only in so far as they tell us those things which the apostles and prophets have left in their writings.
12. There are two kinds of difficulty, one arising from the nature of the work itself, and such difficulty has value for merit; the other arising from the disorder or sluggishness of the will. This latter rather lessens merit, and habit destroys it but not the former.
13. Natural powers have a determination to one object, and so do not need a habit to give them this determination as do the rational powers, which are related equally to things opposed to each other.
