Thomas Aquinas - Summa Theologica, Part II-II (Secunda Secundae)

Obj. 2: Further, science is acquired by reasons. Now sacred writers employ reasons to inculcate things that are of faith. Therefore such things can be an object of science.

Obj. 3: Further, things which are demonstrated are an object of science, since a "demonstration is a syllogism that produces science." Now certain matters of faith have been demonstrated by the philosophers, such as the Existence and Unity of God, and so forth. Therefore things that are of faith can be an object of science.

Obj. 4: Further, opinion is further from science than faith is, since faith is said to stand between opinion and science. Now opinion and science can, in a way, be about the same object, as stated in Poster. i. Therefore faith and science can be about the same object also.

On the contrary, Gregory says (Hom. xxvi in Evang.) that "when a thing is manifest, it is the object, not of faith, but of perception." 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.

I answer that, All science is derived from self-evident and therefore "seen" principles; wherefore all objects of science must needs be, in a fashion, seen.

Now as stated above (A. 4), it is impossible that one and the same thing should be believed and seen by the same person. Hence it is equally impossible for one and the same thing to be an object of science and of belief for the same person. It may happen, however, that a thing which is an object of vision or science for one, is believed by another: since we hope to see some day what we now believe about the Trinity, according to 1 Cor. 13:12: "We see now through a glass in a dark manner; but then face to face": which vision the angels possess already; so that what we believe, they see. In like manner it may happen that what is an object of vision or scientific knowledge for one man, even in the state of a wayfarer, is, for another man, an object of faith, because he does not know it by demonstration.

Nevertheless that which is proposed to be believed equally by all, is equally unknown by all as an object of science: such are the things which are of faith simply. Consequently faith and science are not about the same things.

Reply Obj. 1: Unbelievers are in ignorance of things that are of faith, for neither do they see or know them in themselves, nor do they know them to be credible. The faithful, on the other hand, know them, not as by demonstration, but by the light of faith which makes them see that they ought to believe them, as stated above (A. 4, ad 2, 3).

Reply Obj. 2: 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. from the authority of Holy Writ, as Dionysius declares (Div. Nom. ii). Whatever is based on these principles is as well proved in the eyes of the faithful, as a conclusion drawn from self-evident principles is in the eyes of all. Hence again, theology is a science, as we stated at the outset of this work (P. I, Q. 1, A. 2).

Reply Obj. 3: 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.

Reply Obj. 4: As the Philosopher says (Poster. i), "science and opinion about the same object can certainly be in different men," as we have stated above about science and faith; yet it is possible for one and the same man to have science and faith about the same thing relatively, i.e. in relation to the object, but not in the same respect. For it is possible for the same person, about one and the same object, to know one thing and to think another: and, in like manner, one may know by demonstration the unity of the Godhead, and, by faith, the Trinity. On the other hand, in one and the same man, about the same object, and in the same respect, science is incompatible with either opinion or faith, yet for different reasons. Because science is incompatible with opinion about the same object simply, for the reason that science demands that its object should be deemed impossible to be otherwise, whereas it is essential to opinion, that its object should be deemed possible to be otherwise. Yet that which is the object of faith, on account of the certainty of faith, is also deemed impossible to be otherwise; and the reason why science and faith cannot be about the same object and in the same respect is because the object of science is something seen whereas the object of faith is the unseen, as stated above. _______________________

SIXTH ARTICLE [II-II, Q. 1, Art. 6]

Whether Those Things That Are of Faith Should Be Divided into Certain

Articles?

Objection 1: It would seem that those things that are of faith should not be divided into certain articles. For all things contained in Holy Writ are matters of faith. But these, by reason of their multitude, cannot be reduced to a certain number. Therefore it seems superfluous to distinguish certain articles of faith.

Obj. 2: Further, material differences can be multiplied indefinitely, and therefore art should take no notice of them. Now the formal aspect of the object of faith is one and indivisible, as stated above (A. 1), viz. the First Truth, so that matters of faith cannot be distinguished in respect of their formal object. Therefore no notice should be taken of a material division of matters of faith into articles.

Obj. 3: Further, it has been said by some [*Cf. William of Auxerre, Summa Aurea] that "an article is an indivisible truth concerning God, exacting [arctans] our belief." Now belief is a voluntary act, since, as Augustine says (Tract. xxvi in Joan.), "no man believes against his will." Therefore it seems that matters of faith should not be divided into articles.

On the contrary, Isidore says: "An article is a glimpse of Divine truth, tending thereto." Now we can only get a glimpse of Divine truth by way of analysis, since things which in God are one, are manifold in our intellect. Therefore matters of faith should be divided into articles.

I answer that, the word "article" is apparently derived from the Greek; for the Greek arthron [*Cf. William of Auxerre, Summa Aurea] which the Latin renders "articulus," signifies a fitting together of distinct parts: wherefore the small parts of the body which fit together are called the articulations of the limbs. Likewise, in the Greek grammar, articles are parts of speech which are affixed to words to show their gender, number or case. Again in rhetoric, articles are parts that fit together in a sentence, for Tully says (Rhet. iv) that an article is composed of words each pronounced singly and separately, thus: "Your passion, your voice, your look, have struck terror into your foes."

Hence matters of Christian faith are said to contain distinct articles, in so far as they are divided into parts, and fit together. Now the object of faith is something unseen in connection with God, as stated above (A. 4). Consequently any matter that, for a special reason, is unseen, is a special article; whereas when several matters are known or not known, under the same aspect, we are not to distinguish various articles. Thus one encounters one difficulty in seeing that God suffered, and another in seeing that He rose again from the dead, wherefore the article of the Resurrection is distinct from the article of the Passion. But that He suffered, died and was buried, present the same difficulty, so that if one be accepted, it is not difficult to accept the others; wherefore all these belong to one article.
