Summa Theologica by Saint Thomas Aquinas (whitelam books .TXT) 📕

words quoted must be taken to mean either that the life of unbelievers cannot be sinless, since without faith no sin is taken away, or that whatever they do out of unbelief, is a sin. Hence the same authority adds: "Because every one that lives or acts according to his unbelief, sins grievously."

Reply Obj. 2: Faith directs the intention with regard to the supernatural last end: but even the light of natural reason can direct the intention in respect of a connatural good.

Reply Obj. 3: Unbelief does not so wholly destroy natural reason in unbelievers, but that some knowledge of the truth remains in them, whereby they are able to do deeds that are generically good. With regard, however, to Cornelius, it is to be observed that he was not an unbeliever, else his works would not have been acceptable to God, whom none can please without faith. Now he had implicit faith, as the truth of the Gospel was not yet made manifest: hence Peter was sent to him to give him fuller instruction in the faith. _______________________

FIFTH ARTICLE [II-II, Q. 10, Art. 5]

Whether There Are Several Species of Unbelief?

Objection 1: It would seem that there are not several species of unbelief. For, since faith and unbelief are contrary to one another, they must be about the same thing. Now the formal object of faith is the First Truth, whence it derives its unity, although its matter contains many points of belief. Therefore the object of unbelief also is the First Truth; while the things which an unbeliever disbelieves are the matter of his unbelief. Now the specific difference depends not on material but on formal principles. Therefore there are not several species of unbelief, according to the various points which the unbeliever disbelieves.

Obj. 2: Further, it is possible to stray from the truth of faith in an infinite number of ways. If therefore the various species of unbelief correspond to the number of various errors, it would seem to follow that there is an infinite number of species of unbelief, and consequently, that we ought not to make these species the object of our consideration.

Obj. 3: Further, the same thing does not belong to different species. Now a man may be an unbeliever through erring about different points of truth. Therefore diversity of errors does not make a diversity of species of unbelief: and so there are not several species of unbelief.

On the contrary, Several species of vice are opposed to each virtue, because "good happens in one way, but evil in many ways," according to Dionysius (Div. Nom. iv) and the Philosopher (Ethic. ii, 6). Now faith is a virtue. Therefore several species of vice are opposed to it.

I answer that, As stated above (I-II, Q. 55, A. 4; I-II, Q. 64, A. 1), every virtue consists in following some rule of human knowledge or operation. Now conformity to a rule happens one way in one matter, whereas a breach of the rule happens in many ways, so that many vices are opposed to one virtue. The diversity of the vices that are opposed to each virtue may be considered in two ways, first, with regard to their different relations to the virtue: and in this way there are determinate species of vices contrary to a virtue: thus to a moral virtue one vice is opposed by exceeding the virtue, and another, by falling short of the virtue. Secondly, the diversity of vices opposed to one virtue may be considered in respect of the corruption of the various conditions required for that virtue. In this way an infinite number of vices are opposed to one virtue, e.g. temperance or fortitude, according to the infinite number of ways in which the various circumstances of a virtue may be corrupted, so that the rectitude of virtue is forsaken. For this reason the Pythagoreans held evil to be infinite.

Accordingly we must say that if unbelief be considered in comparison to faith, there are several species of unbelief, determinate in number. For, since the sin of unbelief consists in resisting the faith, this may happen in two ways: either the faith is resisted before it has been accepted, and such is the unbelief of pagans or heathens; or the Christian faith is resisted after it has been accepted, and this either in the figure, and such is the unbelief of the Jews, or in the very manifestation of truth, and such is the unbelief of heretics. Hence we may, in a general way, reckon these three as species of unbelief.

If, however, the species of unbelief be distinguished according to the various errors that occur in matters of faith, there are not determinate species of unbelief: for errors can be multiplied indefinitely, as Augustine observes (De Haeresibus).

Reply Obj. 1: The formal aspect of a sin can be considered in two ways. First, according to the intention of the sinner, in which case the thing to which the sinner turns is the formal object of his sin, and determines the various species of that sin. Secondly, it may be considered as an evil, and in this case the good which is forsaken is the formal object of the sin; which however does not derive its species from this point of view, in fact it is a privation. We must therefore reply that the object of unbelief is the First Truth considered as that which unbelief forsakes, but its formal aspect, considered as that to which unbelief turns, is the false opinion that it follows: and it is from this point of view that unbelief derives its various species. Hence, even as charity is one, because it adheres to the Sovereign Good, while there are various species of vice opposed to charity, which turn away from the Sovereign Good by turning to various temporal goods, and also in respect of various inordinate relations to God, so too, faith is one virtue through adhering to the one First Truth, yet there are many species of unbelief, because unbelievers follow many false opinions.

Reply Obj. 2: This argument considers the various species of unbelief according to various points in which errors occur.

Reply Obj. 3: Since faith is one because it believes in many things in relation to one, so may unbelief, although it errs in many things, be one in so far as all those things are related to one. Yet nothing hinders one man from erring in various species of unbelief, even as one man may be subject to various vices, and to various bodily diseases. _______________________

SIXTH ARTICLE [II-II, Q. 10, Art. 6]

Whether the Unbelief of Pagans or Heathens Is Graver Than Other Kinds?

Objection 1: It would seem that the unbelief of heathens or pagans is graver than other kinds. For just as bodily disease is graver according as it endangers the health of a more important member of the body, so does sin appear to be graver, according as it is opposed to that which holds a more important place in virtue. Now that which is most important in faith, is belief in the unity of God, from which the heathens deviate by believing in many gods. Therefore their unbelief is the gravest of all.

Obj. 2: Further, among heresies, the more detestable are those which contradict the truth of faith in more numerous and more important points: thus, the heresy of Arius, who severed the Godhead, was more detestable than that of Nestorius who severed the humanity of Christ from the Person of God the Son. Now the heathens deny the faith in more numerous and more important points than Jews and heretics; since they do not accept the faith at all. Therefore their unbelief is the gravest.

Obj. 3: Further, every good diminishes evil. Now there is some good in the Jews, since they believe in the Old Testament as being from God, and there is some good in heretics, since they venerate the New Testament. Therefore they sin less grievously than heathens, who receive neither Testament.

On the contrary, It is written (2 Pet. 2:21): "It had been better for them not to have known the way of justice, than after they have known it, to turn back." Now the heathens have not known the way of justice, whereas heretics and Jews have abandoned it after knowing it in some way. Therefore theirs is the graver sin.

I answer that, As stated above (A. 5), two things may be considered in unbelief. One of these is its relation to faith: and from this point of view, he who resists the faith after accepting it, sins more grievously against faith, than he who resists it without having accepted it, even as he who fails to fulfil what he has promised, sins more grievously than if he had never promised it. In this way the unbelief of heretics, who confess their belief in the Gospel, and resist that faith by corrupting it, is a more grievous sin than that of the Jews, who have never accepted the Gospel faith. Since, however, they accepted the figure of that faith in the Old Law, which they corrupt by their false interpretations, their unbelief is a more grievous sin than that of the heathens, because the latter have not accepted the Gospel faith in any way at all.

The second thing to be considered in unbelief is the corruption of matters of faith. In this respect, since heathens err on more points than Jews, and these in more points than heretics, the unbelief of heathens is more grievous than the unbelief of the Jews, and that of the Jews than that of the heretics, except in such cases as that of the Manichees, who, in matters of faith, err even more than heathens do.

Of these two gravities the first surpasses the second from the point of view of guilt; since, as stated above (A. 1) unbelief has the character of guilt, from its resisting faith rather than from the mere absence of faith, for the latter as was stated (A. 1) seems rather to bear the character of punishment. Hence, speaking absolutely, the unbelief of heretics is the worst.

This suffices for the Replies to the Objections. _______________________

SEVENTH ARTICLE [II-II, Q. 10, Art. 7]

Whether One Ought to Dispute with Unbelievers in Public?

Objection 1: It would seem that one ought not to dispute with unbelievers in public. For the Apostle says (2 Tim. 2:14): "Contend not in words, for it is to no profit, but to the subverting of the hearers." But it is impossible to dispute with unbelievers publicly without contending in words. Therefore one ought not to dispute publicly with unbelievers.

Obj. 2: Further, the law of Martianus Augustus confirmed by the canons [*De Sum. Trin. Cod. lib. i, leg. Nemo] expresses itself thus: "It is an insult to the judgment of the most religious synod, if anyone ventures to debate or dispute in public about matters which have once been judged and disposed of." Now all matters of faith have been decided by the holy councils. Therefore it is an insult to the councils, and consequently a grave sin to presume to dispute in public about matters of faith.

Obj. 3: Further, disputations are conducted by means of arguments. But an argument is a reason in settlement of a dubious matter: whereas things that are of faith, being most certain, ought not to be a matter of doubt. Therefore one ought not to dispute in public about matters of faith.

On the contrary, It is written (Acts 9:22, 29) that "Saul increased much more in strength, and confounded the Jews," and that "he spoke . . . to the gentiles and disputed with the Greeks."

I answer that, In disputing about the faith, two things must be observed: one on the part of the disputant; the other on the part of his hearers. On the part of the disputant, we must consider his intention. For if he were to dispute as though he had doubts about the faith, and did not hold the truth of faith for certain, and as though he intended to probe it with arguments, without doubt he would sin, as being doubtful of the faith and an unbeliever. On the other hand, it is praiseworthy to dispute about the faith in order to confute errors, or for practice.

On the part of the hearers we must consider whether those who hear the disputation are instructed and firm in the faith, or simple and wavering. As to those who are well instructed and firm in the faith, there can be no danger in disputing about the faith in their presence. But as to simple-minded people, we must make a distinction; because either they are provoked and molested by unbelievers, for instance, Jews or heretics, or pagans who strive to corrupt the faith in them, or else they
