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

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 are not subject to provocation in this matter, as in those countries where there are no unbelievers. In the first case it is necessary to dispute in public about the faith, provided there be those who are equal and adapted to the task of confuting errors; since in this way simple people are strengthened in the faith, and unbelievers are deprived of the opportunity to deceive, while if those who ought to withstand the perverters of the truth of faith were silent, this would tend to strengthen error. Hence Gregory says (Pastor. ii, 4): "Even as a thoughtless speech gives rise to error, so does an indiscreet silence leave those in error who might have been instructed." On the other hand, in the second case it is dangerous to dispute in public about the faith, in the presence of simple people, whose faith for this very reason is more firm, that they have never heard anything differing from what they believe. Hence it is not expedient for them to hear what unbelievers have to say against the faith.

Reply Obj. 1: The Apostle does not entirely forbid disputations, but such as are inordinate, and consist of contentious words rather than of sound speeches.

Reply Obj. 2: That law forbade those public disputations about the faith, which arise from doubting the faith, but not those which are for the safeguarding thereof.

Reply Obj. 3: One ought to dispute about matters of faith, not as though one doubted about them, but in order to make the truth known, and to confute errors. For, in order to confirm the faith, it is necessary sometimes to dispute with unbelievers, sometimes by defending the faith, according to 1 Pet. 3:15: "Being ready always to satisfy everyone that asketh you a reason of that hope and faith which is in you [*Vulg.: 'Of that hope which is in you'; St. Thomas' reading is apparently taken from Bede]." Sometimes again, it is necessary, in order to convince those who are in error, according to Titus 1:9: "That he may be able to exhort in sound doctrine and to convince the gainsayers." _______________________

EIGHTH ARTICLE [II-II, Q. 10, Art. 8]

Whether Unbelievers Ought to Be Compelled to the Faith?

Objection 1: It would seem that unbelievers ought by no means to be compelled to the faith. For it is written (Matt. 13:28) that the servants of the householder, in whose field cockle had been sown, asked him: "Wilt thou that we go and gather it up?" and that he answered: "No, lest perhaps gathering up the cockle, you root up the wheat also together with it": on which passage Chrysostom says (Hom. xlvi in Matth.): "Our Lord says this so as to forbid the slaying of men. For it is not right to slay heretics, because if you do you will necessarily slay many innocent persons." Therefore it seems that for the same reason unbelievers ought not to be compelled to the faith.

Obj. 2: Further, we read in the Decretals (Dist. xlv can., De Judaeis): "The holy synod prescribes, with regard to the Jews, that for the future, none are to be compelled to believe." Therefore, in like manner, neither should unbelievers be compelled to the faith.

Obj. 3: Further, Augustine says (Tract. xxvi in Joan.) that "it is possible for a man to do other things against his will, but he cannot believe unless he is willing." Therefore it seems that unbelievers ought not to be compelled to the faith.

Obj. 4: It is said in God's person (Ezech. 18:32 [*Ezech. 33:11]): "I desire not the death of the sinner [Vulg.: 'of him that dieth']." Now we ought to conform our will to the Divine will, as stated above (I-II, Q. 19, AA. 9, 10). Therefore we should not even wish unbelievers to be put to death.

On the contrary, It is written (Luke 14:23): "Go out into the highways and hedges; and compel them to come in." Now men enter into the house of God, i.e. into Holy Church, by faith. Therefore some ought to be compelled to the faith.

I answer that, Among unbelievers there are some who have never received the faith, such as the heathens and the Jews: and these are by no means to be compelled to the faith, in order that they may believe, because to believe depends on the will: nevertheless they should be compelled by the faithful, if it be possible to do so, so that they do not hinder the faith, by their blasphemies, or by their evil persuasions, or even by their open persecutions. It is for this reason that Christ's faithful often wage war with unbelievers, not indeed for the purpose of forcing them to believe, because even if they were to conquer them, and take them prisoners, they should still leave them free to believe, if they will, but in order to prevent them from hindering the faith of Christ.
