Thomas Aquinas

AD 1274
551. – Above, the Apostle showed Christ’s superiority in many ways by preferring Him to the angels, to Moses and to Aaron, and advised the faithful to be united to Christ. Since this union consists principally in faith and begins with faith: ‘That Christ may dwell by faith in your hearts’ (Eph. 3:17), the Apostle proceeds to recommend this faith and does three things: first he describes faith; secondly, he gives various examples of it (v. 2); thirdly, he exhorts them to the things which pertain to faith (chap. 12). 552. – He gives a definition of faith which is complete but obscure. Hence, it should be noted that in attempting to define any virtue perfectly, one must mention its proper matter with which it deals, and its end; because habits are recognized by their acts, and acts by their objects. Therefore, it is necessary to mention the act and its order to its object and end. Thus, the definition of courage must mention its proper matter with which it deals, namely, fears and aggressions, and its end, which is the good of the republic. Now, since faith is a theological virtue, its object and end are the same, namely, God. First, he mentions its order to the end; secondly, its proper matter (v. 1b). 553. – But it should be noted that the act of faith is to believe, because it is an act of the intellect narrowed to one thing by the command of the will. Hence, to believe is to cogitate with assent, as Augustine says in The Predestination of the Saints. Therefore, the object of faith and of the will must coincide. But the object of faith is the first truth, in which the end of the will consists, namely, happiness, But it is present one way on earth, and another way in heaven, because on earth the first truth is not possessed and, consequently, not seen: for in regard to things that are above the soul, to possess and to see are the same, as Augustine says in Book of 83 Questions. Hence, they are only hoped for: ‘But hope that is sees in not hope. For what a man sees, why does he hope for?’ (Rom. 8:24). Therefore, the first truth, not seen but hoped for, is the end of the will on earth and, consequently, is the object of faith, because its end and object are the same. But the ultimate end of faith in heaven, which we tend toward by faith, is happiness, which consists in the clear vision of God: ‘This is eternal life: to know thee, the only true God, and Jesus Christ whom you have sent’ (Jn. 17:3). But such is the hope of believers: ‘He has regenerated us unto a lively hope’ (1 Pt. 1:3). The end, therefore, of faith on earth is the attainment of the thing hoped for, namely, of eternal happiness; hence, he says, of things hoped for. 554. – But a question arises: since faith is prior to hope, why is it defined in terms of hope? For it is customary to define the later by the previous, and not vice versa. I answer that the answer should be obvious from what has been said, namely, that the object and end of faith are the same. Therefore, since the attainment of the things hoped for is its end, it must also be its object. For it has been stated above that a habit must be defined by the order of its act to its object. But the true and the good, even though when considered in themselves are convertible as far as their supposits are concerned, differ in conception. Hence, they are diversely related to each other, because the true is a good and a good is true. In like manner, the intellect and will, which are distinguished on the basis of the distinction between the true and the good, have a diverse relationship to each other. For inasmuch as the intellect apprehends truth and anything contained in it, the true is a good; hence, the good is under the true: but inasmuch as the will moves, the true is under the good. Therefore, in the order of knowing, the intellect is prior; but in the order of moving, the will is prior. Therefore, because the intellect is moved to the act of faith by the command of the will, in the order of moving, the will is prior. Therefore, the prior is not being defined in terms of the later, because, as has been stated, in the definition of faith, the order of the act to its object, which is the same as the end, must be mentioned. But the end and the good are the same, as it says in Phys. II. But in the order to the good, the will, which is the subject of hope, is prior. 555. – But why not say, ‘of things to be loved,’ rather than of things to be hoped for? The reason is because charity is concerned with things that are present or absent. Therefore, because the unpossessed end is the object of faith, he says, of things to be hoped for. Nor does it make any difference that the thing to be hoped for is also the object of hope, because it is necessary that faith be ordained to an end, which coincides with the object of those virtues by which the will is made perfect; since faith pertains to the will as moved by the intellect. 556. – But since faith is one virtue, because it is called one habit (for its object is one), why not say ‘of the thing to be hoped for,’ instead of things to be hoped for? I answer that happiness, which is essentially one thing in itself, because it consists in the vision of God, is the principle and root from which the many good things contained under it are derived: for example, the characteristics of the body, companionship with the saints, and many other good things. Therefore, in order to show that all these pertain to faith, he speaks in the plural. 557. – The word, substance, which appears in the definition, can be explained in a number of ways: in one way, causally, and then it has two senses: one which is substance, i.e., making the things hoped for be present in us. This it does in two ways: in one way, by meriting, as it were; for from the fact that a person makes his intellect captive and submissive to the things of faith, he deserves some day to see the things he hopes for: for vision is the reward of faith. In another way, as though by its property, bringing it about that what is believed really to lie in the future, be somehow already possessed, provided one believe in God. In another way, we can explain the word, substance, essentially, as if faith is the substance, i.e., the essence of things to be hoped for. Hence, in Greek it is defined as ‘the hypostasis of things to be hoped for.’ For the essence of happiness is no less than the vision of God: ‘This is eternal life: that they may know you, the only true God, and Jesus Christ whom you have sent’ (Jn. 17:3). Hence, in the book, On the Trinity. Augustine says: ‘This contemplation is promised to us; the end of all actions.’ Therefore, the full vision of God is the essence of happiness. We also see this in the liberal sciences, which, if a person wishes to learn them, he must first accept its principles, which he must believe when they are delivered to him by the teacher. For a learner must believe, as it is stated in 1 Posterior Analytics. And in those principles the entire science is somehow contained, as conclusions are contained in their principles, and an effect in its cause. Therefore, one who has the principles of a science, say geometry, has its substance. And if geometry were the substance of happiness, a person who possessed the principles of geometry would, in a sense, have the substance of happiness. But our faith consists in believing that the blessed will see and enjoy God. Therefore, if we will to reach that state, it is necessary that we believe the principles of that knowledge. And these principles are the articles of faith, which contain the summary of this knowledge, because the vision of the triune God makes us happy. And this is one article; hence we believe this. Consequently, he says, the assurance [substance] of things to be hoped for: ‘We see now through a glass in a dark manner; but then face to fact’ (1 Cor. 13:12). As if to say: we shall be happy when we see face to face that which we now see in a glass and in a dark manner. In these words is shown the relationship of the act of faith to its end, because faith is ordained to things to be hoped for, being, as it were, a beginning in which the whole is, as it were, virtually contained, as conclusions in principles. 558. – Then when he says, the conviction [evidence] of things that appear not, he touches the act of faith in regard to its proper matter. But the act proper to faith, even though it is in relation to the will, as has been said, is nevertheless in the intellect, as in a subject, because its object is the true, which properly pertains to the intellect. But there is a difference among the acts of the intellect: for some are habits of the intellect which imply complete certitude and perfect understanding of that which is understood, as is clear in the habit of understanding, which is the habit of first principles, because one who understands that every whole is great than its part sees this and is certain. But the habit of science also does this: thus the habits of understanding and of science will produce certitude and vision. But there are others which beget neither, namely, doubt and opinion. But faith is midway between these: because, as has been stated, faith produces assent in the intellect which can be caused in two ways: in one way, because the intellect is moved to assent because of the evidence of the object which is per se knowable, as in the habit of principles, or known through something else, which is per se knowable, as in the science of astronomy. In another way, it assents to something not because of the evidence of the object, by which it is not sufficiently moved (hence it is not certain), but it either doubts, namely, when there is no more evidence for one side than for the other; or it opines, if it does have reason for one side, but without satisfying the intellect, so that there is fear in regard to the opposite side. But faith does not suggest either of these absolutely: because there is no evidence, as there is in understanding and science, nor is there doubt, as in doubt and opinion; but it fixes on one side with certainty and firm adherence by a voluntary choice. But this choice rests on God’s authority, and by it the intellect is fixed, so that it clings firmly to the things of faith and assents to them with the greatest of certainty. Therefore, to believe is to know with assent. Therefore, the proper matter of the habit of faith are things that appear not. For appearance has knowledge, but not faith, as Gregory says. But the act of faith is certain adherence, which the Apostle calls evidence, taking the cause for the effect, because evidence produces faith about a doubtful matter. For evidence is the reason for believing a doubted thing. Or if we follow the etymology of the word, evidence (argument), which means arguing the mind, then he is taking the effect for the cause, because the mind is compelled to assent because of the thing’s certainty. Hence, it is called the evidence of things that appear not, i.e., a sure and certain apprehension of things it does not see. Now, if someone were to reduce those words to their correct form, he could say that faith is a habit of the mind by which eternal life is begun in us and makes the intellect assent to things that it does not see. Therefore, it is obvious that the Apostle has defined faith completely, but not clearly. [Where we have evidence another version has conviction, because on God’s authority the intellect is convinced about things it does not see]. 559. – By that definition, faith is distinguished from all the other habits of the intellect. For the fact that it is called evidence, faith is distinguished from opinion, doubt and suspicion, because these three doe not cause the intellect to adhere to something firmly. By the words, of things to be hoped for, it is distinguished from ordinary faith which is not ordained to happiness. For by proper definition a thing is made known and distinguished from all else, as in this case; hence, all the others are reduced to it. 560. – But it seems incorrect to say, of things that appear not, as it says in Jn (20:26): ‘Thomas saw and believed.’ Furthermore, we believe that there is one God, a fact which is demonstrated by philosophers. I answer that faith is taken in two senses: in the proper sense, it is concerned with things not seen and not known, as is clear from the above. But inasmuch as there cannot be greater certainty of a conclusion than of the principle from which it is drawn, because principles are always more certain than the conclusions, it follows that since the principles of faith are not evident, neither are its conclusions. Hence, the intellect does not assent to the conclusions as to things known or seen. But taken in a general sense, it excludes all knowledge that is certain; that is the sense in which it is taken by Augustine in the Gospel Questions, when he says that faith is concerned with things that are seen. But the Apostle is speaking in the first sense. Furthermore, it must be said of Thomas that, as Gregory says, he saw one thing and believed something else: for he saw the humanity and believed the divinity. To the objection based on demonstration, the answer is that nothing prohibits one thing being seen by one person and believed by another, as is obvious in diverse states. For what is not seen on earth is seen by the angels. Therefore, what I believe, an angel sees. Similarly, what is seen by the prophets, for example, that God is one and incorporeal, must be believed by the illiterate; just as an illiterate person believes in an eclipse which an astronomer sees. However, in such matters faith is taken in a different sense. But there are some things which absolutely transcend the state of the present life; and in regard to these there is faith in the strict sense.
