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

I answer that, According to the various interpretations of the sin against the Holy Ghost, there are various ways in which it may be said that it cannot be forgiven. For if by the sin against the Holy Ghost we understand final impenitence, it is said to be unpardonable, since in no way is it pardoned: because the mortal sin wherein a man perseveres until death will not be forgiven in the life to come, since it was not remitted by repentance in this life.

According to the other two interpretations, it is said to be unpardonable, not as though it is nowise forgiven, but because, considered in itself, it deserves not to be pardoned: and this in two ways. First, as regards the punishment, since he that sins through ignorance or weakness, deserves less punishment, whereas he that sins through certain malice, can offer no excuse in alleviation of his punishment. Likewise those who blasphemed against the Son of Man before His Godhead was revealed, could have some excuse, on account of the weakness of the flesh which they perceived in Him, and hence, they deserved less punishment; whereas those who blasphemed against His very Godhead, by ascribing to the devil the works of the Holy Ghost, had no excuse in diminution of their punishment. Wherefore, according to Chrysostom's commentary (Hom. xlii in Matth.), the Jews are said not to be forgiven this sin, neither in this world nor in the world to come, because they were punished for it, both in the present life, through the Romans, and in the life to come, in the pains of hell. Thus also Athanasius adduces the example of their forefathers who, first of all, wrangled with Moses on account of the shortage of water and bread; and this the Lord bore with patience, because they were to be excused on account of the weakness of the flesh: but afterwards they sinned more grievously when, by ascribing to an idol the favors bestowed by God Who had brought them out of Egypt, they blasphemed, so to speak, against the Holy Ghost, saying (Ex. 32:4): "These are thy gods, O Israel, that have brought thee out of the land of Egypt." Therefore the Lord both inflicted temporal punishment on them, since "there were slain on that day about three and twenty thousand men" (Ex. 32:28), and threatened them with punishment in the life to come, saying, (Ex. 32:34): "I, in the day of revenge, will visit this sin . . . of theirs."

Secondly, this may be understood to refer to the guilt: thus a disease is said to be incurable in respect of the nature of the disease, which removes whatever might be a means of cure, as when it takes away the power of nature, or causes loathing for food and medicine, although God is able to cure such a disease. So too, the sin against the Holy Ghost is said to be unpardonable, by reason of its nature, in so far as it removes those things which are a means towards the pardon of sins. This does not, however, close the way of forgiveness and healing to an all-powerful and merciful God, Who, sometimes, by a miracle, so to speak, restores spiritual health to such men.

Reply Obj. 1: We should despair of no man in this life, considering God's omnipotence and mercy. But if we consider the circumstances of sin, some are called (Eph. 2:2) "children of despair" [*Filios diffidentiae, which the Douay version renders "children of unbelief."].

Reply Obj. 2: This argument considers the question on the part of
God's omnipotence, not on that of the circumstances of sin.

Reply Obj. 3: In this life the free-will does indeed ever remain subject to change: yet sometimes it rejects that whereby, so far as it is concerned, it can be turned to good. Hence considered in itself this sin is unpardonable, although God can pardon it. _______________________

FOURTH ARTICLE [II-II, Q. 14, Art. 4]

Whether a Man Can Sin First of All Against the Holy Ghost?

Objection 1: It would seem that a man cannot sin first of all against the Holy Ghost, without having previously committed other sins. For the natural order requires that one should be moved to perfection from imperfection. This is evident as regards good things, according to Prov. 4:18: "The path of the just, as a shining light, goeth forwards and increases even to perfect day." Now, in evil things, the perfect is the greatest evil, as the Philosopher states (Metaph. v, text. 21). Since then the sin against the Holy Ghost is the most grievous sin, it seems that man comes to commit this sin through committing lesser sins.

Obj. 2: Further, to sin against the Holy Ghost is to sin through certain malice, or through choice. Now man cannot do this until he has sinned many times; for the Philosopher says (Ethic. v, 6, 9) that "although a man is able to do unjust deeds, yet he cannot all at once do them as an unjust man does," viz. from choice. Therefore it seems that the sin against the Holy Ghost cannot be committed except after other sins.

Obj. 3: Further, repentance and impenitence are about the same object. But there is no repentance, except about past sins. Therefore the same applies to impenitence which is a species of the sin against the Holy Ghost. Therefore the sin against the Holy Ghost presupposes other sins.

On the contrary, "It is easy in the eyes of God on a sudden to make a poor man rich" (Ecclus. 11:23). Therefore, conversely, it is possible for a man, according to the malice of the devil who tempts him, to be led to commit the most grievous of sins which is that against the Holy Ghost.

I answer that, As stated above (A. 1), in one way, to sin against the Holy Ghost is to sin through certain malice. Now one may sin through certain malice in two ways, as stated in the same place: first, through the inclination of a habit; but this is not, properly speaking, to sin against the Holy Ghost, nor does a man come to commit this sin all at once, in as much as sinful acts must precede so as to cause the habit that induces to sin. Secondly, one may sin through certain malice, by contemptuously rejecting the things whereby a man is withdrawn from sin. This is, properly speaking, to sin against the Holy Ghost, as stated above (A. 1); and this also, for the most part, presupposes other sins, for it is written (Prov. 18:3) that "the wicked man, when he is come into the depth of sins, contemneth."

Nevertheless it is possible for a man, in his first sinful act, to sin against the Holy Ghost by contempt, both on account of his free-will, and on account of the many previous dispositions, or again, through being vehemently moved to evil, while but feebly attached to good. Hence never or scarcely ever does it happen that the perfect sin all at once against the Holy Ghost: wherefore Origen says (Peri Archon. i, 3): "I do not think that anyone who stands on the highest step of perfection, can fail or fall suddenly; this can only happen by degrees and bit by bit."

The same applies, if the sin against the Holy Ghost be taken literally for blasphemy against the Holy Ghost. For such blasphemy as Our Lord speaks of, always proceeds from contemptuous malice.

If, however, with Augustine (De Verb. Dom., Serm. lxxi) we understand the sin against the Holy Ghost to denote final impenitence, it does not regard the question in point, because this sin against the Holy Ghost requires persistence in sin until the end of life.

Reply Obj. 1: Movement both in good and in evil is made, for the most part, from imperfect to perfect, according as man progresses in good or evil: and yet in both cases, one man can begin from a greater (good or evil) than another man does. Consequently, that from which a man begins can be perfect in good or evil according to its genus, although it may be imperfect as regards the series of good or evil actions whereby a man progresses in good or evil.

Reply Obj. 2: This argument considers the sin which is committed through certain malice, when it proceeds from the inclination of a habit.

Reply Obj. 3: If by impenitence we understand with Augustine (De Verb. Dom., Serm. lxxi) persistence in sin until the end, it is clear that it presupposes sin, just as repentance does. If, however, we take it for habitual impenitence, in which sense it is a sin against the Holy Ghost, it is evident that it can precede sin: for it is possible for a man who has never sinned to have the purpose either of repenting or of not repenting, if he should happen to sin. _______________________

OF THE VICES OPPOSED TO KNOWLEDGE AND UNDERSTANDING
(In Three Articles)

We must now consider the vices opposed to knowledge and understanding. Since, however, we have treated of ignorance which is opposed to knowledge, when we were discussing the causes of sins (I-II, Q. 76), we must now inquire about blindness of mind and dulness of sense, which are opposed to the gift of understanding; and under this head there are three points of inquiry:

(1) Whether blindness of mind is a sin?

(2) Whether dulness of sense is a sin distinct from blindness of mind?

(3) Whether these vices arise from sins of the flesh? _______________________

FIRST ARTICLE [II-II, Q. 15, Art. 1]

Whether Blindness of Mind Is a Sin?

Objection 1: It would seem that blindness of mind is not a sin. Because, seemingly, that which excuses from sin is not itself a sin. Now blindness of mind excuses from sin; for it is written (John 9:41): "If you were blind, you should not have sin." Therefore blindness of mind is not a sin.

Obj. 2: Further, punishment differs from guilt. But blindness of mind is a punishment as appears from Isa. 6:10, "Blind the heart of this people," for, since it is an evil, it could not be from God, were it not a punishment. Therefore blindness of mind is not a sin.

Obj. 3: Further, every sin is voluntary, according to Augustine (De Vera Relig. xiv). Now blindness of mind is not voluntary, since, as Augustine says (Confess. x), "all love to know the resplendent truth," and as we read in Eccles. 11:7, "the light is sweet and it is delightful for the eyes to see the sun." Therefore blindness of mind is not a sin.

On the contrary, Gregory (Moral. xxxi, 45) reckons blindness of mind among the vices arising from lust.

I answer that, Just as bodily blindness is the privation of the principle of bodily sight, so blindness of mind is the privation of the principle of mental or intellectual sight. Now this has a threefold principle. One is the light of natural reason, which light, since it pertains to the species of the rational soul, is never forfeit from the soul, and yet, at times, it is prevented from exercising its proper act, through being hindered by the lower powers which the human intellect needs in order to understand, for instance in the case of imbeciles and madmen, as stated in the First Part (Q. 84, AA. 7, 8).

Another principle of intellectual sight is a certain habitual light superadded to the natural light of reason, which light is sometimes forfeit from the soul. This privation is blindness, and is a punishment, in so far as the privation of the light of grace is a punishment. Hence it is written concerning some (Wis. 2:21): "Their own malice blinded them."

A third principle of intellectual sight is an intelligible principle, through which a man understands other things; to which principle a man may attend or not attend. That he does not attend thereto happens in two ways. Sometimes it is due to the fact that a man's will is deliberately turned away from the consideration of that principle, according to Ps. 35:4, "He would not understand, that he might do well": whereas sometimes it is due to the mind being more busy about things which it loves more, so as to be hindered thereby from considering this principle, according to Ps. 57:9, "Fire," i.e. of concupiscence, "hath fallen on them and they shall not see the sun." In either of these ways blindness of mind is a sin.

Reply Obj. 1: The blindness that excuses from sin is that which arises from the natural defect of one who cannot see.

Reply Obj. 2: This argument considers the second kind of blindness which is a punishment.

Reply Obj. 3: To understand the
