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.
Objection 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.
Objection 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 [*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.
Reply to Objection 1: Some things are proposed to our belief are in themselves of faith, while others are of faith, not in themselves but only in relation to others: even as in sciences certain propositions are put forward on their own account, while others are put forward in order to manifest others. Now, since the chief object of faith consists in those things which we hope to see, according to Heb. 11:2 : "Faith is the substance of things to be hoped for," it follows that those things are in themselves of faith, which order us directly to eternal life. Such are the Trinity of Persons in Almighty God [*The Leonine Edition reads: The Three Persons, the omnipotence of God, etc.], the mystery of Christ's Incarnation, and the like: and these are distinct articles of faith. On the other hand certain things in Holy Writ are proposed to our belief, not chiefly on their own account, but for the manifestation of those mentioned above: for instance, that Abraham had two sons, that a dead man rose again at the touch of Eliseus' bones, and the like, which are related in Holy Writ for the purpose of manifesting the Divine mystery or the Incarnation of Christ: and such things should not form distinct articles.
Reply to Objection 2: The formal aspect of the object of faith can be taken in two ways: first, on the part of the thing believed, and thus there is one formal aspect of all matters of faith, viz. the First Truth: and from this point of view there is no distinction of articles. Secondly, the formal aspect of matters of faith, can be considered from our point of view; and thus the formal aspect of a matter of faith is that it is something unseen; and from this point of view there are various distinct articles of faith, as we saw above.
Reply to Objection 3: This definition of an article is taken from an etymology of the word as derived from the Latin, rather than in accordance with its real meaning, as derived from the Greek: hence it does not carry much weight. Yet even then it could be said that although faith is exacted of no man by a necessity of coercion, since belief is a voluntary act, yet it is exacted of him by a necessity of end, since "he that cometh to God must believe that He is," and "without faith it is impossible to please God," as the Apostle declares ( Heb. 11:6 ).
Whether the articles of faith have increased in course of time?
Objection 1: It would seem that the articles of faith have not increased in course of time. Because, as the Apostle says ( Heb. 11:1 ), "faith is the substance of things to be hoped for." Now the same things are to be hoped for at all times. Therefore, at all times, the same things are to be believed.
Objection 2: Further, development has taken place, in sciences devised by man, on account of the lack of knowledge in those who discovered them, as the Philosopher observes (Metaph. ii). Now the doctrine of faith was not devised by man, but was delivered to us by God, as stated in Eph. 2:8 : "It is the gift of God." Since then there can be no lack of knowledge in God, it seems that knowledge of matters of faith was perfect from the beginning and did not increase as time went on.
Objection 3: Further, the operation of grace proceeds in orderly fashion no less than the operation of nature. Now nature always makes a beginning with perfect things, as Boethius states (De Consol. iii). Therefore it seems that the operation of grace also began with perfect things, so that those who were the first to deliver the faith, knew it most perfectly.
Objection 4: Further, just as the faith of Christ was delivered to us through the apostles, so too, in the Old Testament, the knowledge of faith was delivered by the early fathers to those who came later, according to Dt. 32:7 : "Ask thy father, and he will declare to thee." Now the apostles were most fully instructed about the mysteries, for "they received them more fully than others, even as they received them earlier," as a gloss says on Rom. 8:23 : "Ourselves also who have the first fruits of the Spirit." Therefore it seems that knowledge of matters of faith has not increased as time went on.
On the contrary, Gregory says (Hom. xvi in Ezech.) that "the knowledge of the holy fathers increased as time went on . . . and the nearer they were to Our Savior's coming, the more fully did they received the mysteries of salvation."
I answer that, The articles of faith stand in the same relation to the doctrine of faith, as self-evident principles to a teaching based on natural reason. Among these principles there is a certain order, so that some are contained implicitly in others; thus all principles are reduced, as to their first principle, to this one: "The same thing cannot be affirmed and denied at the same time," as the Philosopher states (Metaph. iv, text. 9). 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." 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.
Accordingly we must conclude that, as regards the substance of the articles of faith, they have not received any increase as time went on: since whatever those who lived later have believed, was contained, albeit implicitly, in the faith of those Fathers who preceded them. But there was an increase in the number of articles believed explicitly, since to those who lived in later times some were known explicitly which were not known explicitly by those who lived before them. Hence the Lord said to Moses ( Exod. 6:2 , 3 ): "I am the God of Abraham, the God of Isaac, the God of Jacob [*Vulg.: 'I am the Lord that appeared to Abraham, to Isaac, and to Jacob'] . . . and My name Adonai I did not show them": David also said ( Ps. 118:100 ): "I have had understanding above ancients": and the Apostle says ( Eph. 3:5 ) that the mystery of Christ, "in other generations was not known, as it is now revealed to His holy apostles and prophets."
Reply to Objection 1: Among men the same things were always to be hoped for from Christ. But as they did not acquire this hope save through Christ, the further they were removed from Christ in point of time, the further they were from obtaining what they hoped for. Hence the Apostle says ( Heb. 11:13 ): "All these died according to faith, not having received the promises, but beholding them afar off." Now the further off a thing is the less distinctly is it seen; wherefore those who were nigh to Christ's advent had a more distinct knowledge of the good things to be hoped for.
Reply to Objection 2: Progress in knowledge occurs in two ways. First, on the part of the teacher, be he one or many, who makes progress in knowledge as time goes on: and this is the kind of progress that takes place in sciences devised by man. Secondly, on the part of the learner; thus the master, who has perfect knowledge of the art, does not deliver it all at once to his disciple from the very outset, for he would not be able to take it all in, but he condescends to the disciple's capacity and instructs him little by little. It is in this way that men made progress in the knowledge of faith as time went on. Hence the Apostle ( Gal. 3:24 ) compares the state of the Old Testament to childhood.
Reply to Objection 3: Two causes are requisite before actual generation can take place, an agent, namely, and matter. 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. 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.
Reply to Objection 4: The ultimate consummation of grace was effected by Christ, wherefore the time of His coming is called the "time of fulness [*Vulg.: 'fulness of time']" ( Gal. 4:4 ). 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.
Whether the articles of faith are suitably formulated?
Objection 1: It would seem that the articles of faith are unsuitably formulated. For those things, which can be known by demonstration, do not belong to faith as to an object of belief for all, as stated above (A[5] ). Now it can be known by demonstration that there is one God; hence the Philosopher proves this (Metaph. xii, text. 52) and many other philosophers demonstrated the same truth. Therefore that "there is one God" should not be set down as an article of faith.
Objection 2: Further, just as it is necessary to faith that we should believe God to be almighty, so is it too that we should believe Him to be "all-knowing" and "provident for all," about both of which points some have erred. Therefore, among the articles of faith, mention should have been made of God's wisdom and providence, even as of His omnipotence.
Objection 3: Further, to know the Father is the same things as to know the Son, according to Jn. 14:9 : "He that seeth Me, seeth the Father also." Therefore there ought to be but one article about the Father and Son, and, for the same reason, about the Holy Ghost.
