FIRST ARTICLE [II-II, Q. 11, Art. 1]

Whether Heresy Is a Species of Unbelief?

Objection 1: It would seem that heresy is not a species of unbelief.

For unbelief is in the understanding, as stated above (Q. 10, A. 2).

Now heresy would seem not to pertain to the understanding, but rather to the appet.i.tive power; for Jerome says on Gal. 5:19: [*Cf.

Decretals xxiv, qu. iii, cap. 27] ”The works of the flesh are manifest: Heresy is derived from a Greek word meaning choice, whereby a man makes choice of that school which he deems best.” But choice is an act of the appet.i.tive power, as stated above (I-II, Q. 13, A. 1).

Therefore heresy is not a species of unbelief.

Obj. 2: Further, vice takes its species chiefly from its end; hence the Philosopher says (Ethic. v, 2) that ”he who commits adultery that he may steal, is a thief rather than an adulterer.” Now the end of heresy is temporal profit, especially lords.h.i.+p and glory, which belong to the vice of pride or covetousness: for Augustine says (De Util. Credendi i) that ”a heretic is one who either devises or follows false and new opinions, for the sake of some temporal profit, especially that he may lord and be honored above others.” Therefore heresy is a species of pride rather than of unbelief.

Obj. 3: Further, since unbelief is in the understanding, it would seem not to pertain to the flesh. Now heresy belongs to the works of the flesh, for the Apostle says (Gal. 5:19): ”The works of the flesh are manifest, which are fornication, uncleanness,” and among the others, he adds, ”dissensions, sects,” which are the same as heresies. Therefore heresy is not a species of unbelief.

_On the contrary,_ Falsehood is contrary to truth. Now a heretic is one who devises or follows false or new opinions. Therefore heresy is opposed to the truth, on which faith is founded; and consequently it is a species of unbelief.

_I answer that,_ The word heresy as stated in the first objection denotes a choosing. Now choice as stated above (I-II, Q. 13, A. 3) is about things directed to the end, the end being presupposed. Now, in matters of faith, the will a.s.sents to some truth, as to its proper good, as was shown above (Q. 4, A. 3): wherefore that which is the chief truth, has the character of last end, while those which are secondary truths, have the character of being directed to the end.

Now, whoever believes, a.s.sents to someone's words; so that, in every form of unbelief, the person to whose words a.s.sent is given seems to hold the chief place and to be the end as it were; while the things by holding which one a.s.sents to that person hold a secondary place.

Consequently he that holds the Christian faith aright, a.s.sents, by his will, to Christ, in those things which truly belong to His doctrine.

Accordingly there are two ways in which a man may deviate from the rect.i.tude of the Christian faith. First, because he is unwilling to a.s.sent to Christ: and such a man has an evil will, so to say, in respect of the very end. This belongs to the species of unbelief in pagans and Jews. Secondly, because, though he intends to a.s.sent to Christ, yet he fails in his choice of those things wherein he a.s.sents to Christ, because he chooses not what Christ really taught, but the suggestions of his own mind.

Therefore heresy is a species of unbelief, belonging to those who profess the Christian faith, but corrupt its dogmas.

Reply Obj. 1: Choice regards unbelief in the same way as the will regards faith, as stated above.

Reply Obj. 2: Vices take their species from their proximate end, while, from their remote end, they take their genus and cause. Thus in the case of adultery committed for the sake of theft, there is the species of adultery taken from its proper end and object; but the ultimate end shows that the act of adultery is both the result of the theft, and is included under it, as an effect under its cause, or a species under its genus, as appears from what we have said about acts in general (I-II, Q. 18, A. 7). Wherefore, as to the case in point also, the proximate end of heresy is adherence to one's own false opinion, and from this it derives its species, while its remote end reveals its cause, viz. that it arises from pride or covetousness.

Reply Obj. 3: Just as heresy is so called from its being a choosing [*From the Greek _hairein_, to cut off], so does sect derive its name from its being a cutting off (_secando_), as Isidore states (Etym.

viii, 3). Wherefore heresy and sect are the same thing, and each belongs to the works of the flesh, not indeed by reason of the act itself of unbelief in respect of its proximate object, but by reason of its cause, which is either the desire of an undue end in which way it arises from pride or covetousness, as stated in the second objection, or some illusion of the imagination (which gives rise to error, as the Philosopher states in _Metaph._ iv; _Ed. Did._ iii, 5), for this faculty has a certain connection with the flesh, in as much as its act is independent on a bodily organ.

SECOND ARTICLE [II-II, Q. 11, Art. 2]

Whether Heresy Is Properly About Matters of Faith?

Objection 1: It would seem that heresy is not properly about matters of faith. For just as there are heresies and sects among Christians, so were there among the Jews, and Pharisees, as Isidore observes (Etym. viii, 3, 4, 5). Now their dissensions were not about matters of faith. Therefore heresy is not about matters of faith, as though they were its proper matter.

Obj. 2: Further, the matter of faith is the thing believed. Now heresy is not only about things, but also about works, and about interpretations of Holy Writ. For Jerome says on Gal. 5:20 that ”whoever expounds the Scriptures in any sense but that of the Holy Ghost by Whom they were written, may be called a heretic, though he may not have left the Church”: and elsewhere he says that ”heresies spring up from words spoken amiss.” [*St. Thomas quotes this saying elsewhere, in Sent. iv, D, 13, and III, Q. 16, A. 8, but it is not to be found in St. Jerome's works.] Therefore heresy is not properly about the matter of faith.

Obj. 3: Further, we find the holy doctors differing even about matters pertaining to the faith, for example Augustine and Jerome, on the question about the cessation of the legal observances: and yet this was without any heresy on their part. Therefore heresy is not properly about the matter of faith.

_On the contrary,_ Augustine says against the Manichees [*Cf. De Civ.

Dei xviii, 51]: ”In Christ's Church, those are heretics, who hold mischievous and erroneous opinions, and when rebuked that they may think soundly and rightly, offer a stubborn resistance, and, refusing to mend their pernicious and deadly doctrines, persist in defending them.” Now pernicious and deadly doctrines are none but those which are contrary to the dogmas of faith, whereby ”the just man liveth”

(Rom. 1:17). Therefore heresy is about matters of faith, as about its proper matter.
