Thomas Aquinas

“ Now those things are said to be seen which, of themselves, move the intellect or the senses to knowledge of them. Wherefore it is evident that neither faith nor opinion can be of things seen either by the senses or by the intellect. ”

“ In the order of the active cause, the more perfect is naturally first; and in this way nature makes a beginning with perfect things, since the imperfect is not brought to perfection, except by something perfect already in existence. On the other hand, in the order of the material cause, the imperfect comes first, and in this way nature proceeds from the imperfect to the perfect. Now in the manifestation of faith, God is the active cause, having perfect knowledge from all eternity; while man is likened to matter in receiving the influx of God's action. ”

“ Therefore things that are of faith are not the object of perception, whereas what is an object of science is the object of perception. Therefore there can be no faith about things which are an object of science. ”

“ On the other hand, by faith, we do not apprehend the First Truth as it is in itself. Hence the comparison fails.
Art. 3 - Whether anything false can come under faith? Objection 1: It would seem that something false can come under faith. For faith is condivided with hope and charity. Now something false can come under hope, since many hope to have eternal life, who will not obtain it. The same may be said of charity, for many are loved as being good, who, nevertheless, are not good. Therefore something false can be the object of faith. ”

“ Things which can be proved by demonstration are reckoned among the articles of faith, not because they are believed simply by all, but because they are a necessary presupposition to matters of faith, so that those who do not known them by demonstration must know them first of all by faith. ”

“ For the existence of God includes all that we believe to exist in God eternally, and in these our happiness consists; while belief in His providence includes all those things which God dispenses in time, for man's salvation, and which are the way to that happiness: and in this way, again, some of those articles which follow from these are contained in others: thus faith in the Redemption of mankind includes belief in the Incarnation of Christ, His Passion and so forth. ”

“ The truth of faith is contained in Holy Writ, diffusely, under various modes of expression, and sometimes obscurely, so that, in order to gather the truth of faith from Holy Writ, one needs long study and practice, which are unattainable by all those who require to know the truth of faith, many of whom have no time for study, being busy with other affairs. And so it was necessary to gather together a clear summary from the sayings of Holy Writ, to be proposed to the belief of all. ”

“ The fixing of the time, wherein some were deceived was not due to their faith, but to a human conjecture. For it is possible for a believer to have a false opinion through a human conjecture, but it is quite impossible for a false opinion to be the outcome of faith. ”

“ Hence those who were nearest to Christ, wherefore before, like John the Baptist, or after, like the apostles, had a fuller knowledge of the mysteries of faith; for even with regard to man's state we find that the perfection of manhood comes in youth, and that a man's state is all the more perfect, whether before or after, the nearer it is to the time of his youth. ”

“ If, however, we consider materially the things to which faith assents, they include not only God, but also many other things, which, nevertheless, do not come under the assent of faith, except as bearing some relation to God, in as much as, to wit, through certain effects of the Divine operation, man is helped on his journey towards the enjoyment of God. ”

“ The faith of the believer is not directed to such and such accidents of bread, but to the fact that the true body of Christ is under the appearances of sensible bread, when it is rightly consecrated. Hence if it be not rightly consecrated, it does not follow that anything false comes under faith. ”

“ The light of faith makes us see what we believe. For just as, by the habits of the other virtues, man sees what is becoming to him in respect of that habit, so, by the habit of faith, the human mind is directed to assent to such things as are becoming to a right faith, and not to assent to others. ”

“ Secondly the intellect assents to something, not through being sufficiently moved to this assent by its proper object, but through an act of choice, whereby it turns voluntarily to one side rather than to the other: and if this be accompanied by doubt or fear of the opposite side, there will be opinion, while, if there be certainty and no fear of the other side, there will be faith. ”

“ Since the true is the good of the intellect, but not of the appetitive power, it follows that all virtues which perfect the intellect, exclude the false altogether, because it belongs to the nature of a virtue to bear relation to the good alone. ”

“ Hence, among men, the knowledge of faith had to proceed from imperfection to perfection; and, although some men have been after the manner of active causes, through being doctors of faith, nevertheless the manifestation of the Spirit is given to such men for the common good, according to 1 Cor. 12:7; so that the knowledge of faith was imparted to the Fathers who were instructors in the faith, so far as was necessary at the time for the instruction of the people, either openly or in figures. ”

“ The symbol mentions the things about which faith is, in so far as the act of the believer is terminated in them, as is evident from the manner of speaking about them. Now the act of the believer does not terminate in a proposition, but in a thing. For as in science we do not form propositions, except in order to have knowledge about things through their means, so is it in faith. ”

“ On the other hand those virtues which perfect the appetitive faculty, do not entirely exclude the false, for it is possible to act in accordance with justice or temperance, while having a false opinion about what one is doing. ”

“ In like manner all the articles are contained implicitly in certain primary matters of faith, such as God's existence, and His providence over the salvation of man, according to Heb. 11: "He that cometh to God, must believe that He is, and is a rewarder to them that seek Him." ”

“ In the same way Christ's conception and birth, just as the resurrection and life everlasting, can from one point of view be united together in one article, in so far as they are ordained to one end; while, from another point of view, they can be distinct articles, in as much as each one separately presents a special difficulty.
Reply to Objection 4: It belongs to the Son and Holy Ghost to be sent to sanctify the creature; and about this several things have to be believed. ”

“ The reasons employed by holy men to prove things that are of faith, are not demonstrations; they are either persuasive arguments showing that what is proposed to our faith is not impossible, or else they are proofs drawn from the principles of faith, i.e. ”
