God's gifts whereby we are withdrawn from sin, are two: one is the acknowledgment of the truth, against which there is the "resistance of the known truth," when, namely, a man resists the truth which he has acknowledged, in order to sin more freely: while the other is the assistance of inward grace, against which there is "envy of a brother's spiritual good," when, namely, a man is envious not only of his brother's person, but also of the increase of Divine grace in the world.
On the part of sin, there are two things which may withdraw man therefrom: one is the inordinateness and shamefulness of the act, the consideration of which is wont to arouse man to repentance for the sin he has committed, and against this there is "impenitence," not as denoting permanence in sin until death, in which sense it was taken above (for thus it would not be a special sin, but a circumstance of sin), but as denoting the purpose of not repenting. The other thing is the smallness or brevity of the good which is sought in sin, according to Rom. 6:21 : "What fruit had you therefore then in those things, of which you are now ashamed?" The consideration of this is wont to prevent man's will from being hardened in sin, and this is removed by "obstinacy," whereby man hardens his purpose by clinging to sin. Of these two it is written ( Jer. 8:6 ): "There is none that doth penance for his sin, saying: What have I done?" as regards the first; and, "They are all turned to their own course, as a horse rushing to the battle," as regards the second.
Reply to Objection 1: The sins of despair and presumption consist, not in disbelieving in God's justice and mercy, but in contemning them.
Reply to Objection 2: Obstinacy and impenitence differ not only in respect of past and future time, but also in respect of certain formal aspects by reason of the diverse consideration of those things which may be considered in sin, as explained above.
Reply to Objection 3: Grace and truth were the work of Christ through the gifts of the Holy Ghost which He gave to men.
Reply to Objection 4: To refuse to obey belongs to obstinacy, while a feigned repentance belongs to impenitence, and schism to the envy of a brother's spiritual good, whereby the members of the Church are united together.
Whether the sin against the Holy Ghost can be forgiven?
Objection 1: It would seem that the sin against the Holy Ghost can be forgiven. For Augustine says (De Verb. Dom., Serm. lxxi): "We should despair of no man, so long as Our Lord's patience brings him back to repentance." But if any sin cannot be forgiven, it would be possible to despair of some sinners. Therefore the sin against the Holy Ghost can be forgiven.
Objection 2: Further, no sin is forgiven, except through the soul being healed by God. But "no disease is incurable to an all-powerful physician," as a gloss says on Ps. 102:3, "Who healeth all thy diseases." Therefore the sin against the Holy Ghost can be forgiven.
Objection 3: Further, the free-will is indifferent to either good or evil. Now, so long as man is a wayfarer, he can fall away from any virtue, since even an angel fell from heaven, wherefore it is written ( Job 4:18 , 19 ): "In His angels He found wickedness: how much more shall they that dwell in houses of clay?" Therefore, in like manner, a man can return from any sin to the state of justice. Therefore the sin against the Holy Ghost can be forgiven.
On the contrary, It is written ( Mat. 12:32 ): "He that shall speak against the Holy Ghost, it shall not be forgiven him, neither in this world, nor in the world to come": and Augustine says (De Serm. Dom. in Monte i, 22) that "so great is the downfall of this sin that it cannot submit to the humiliation of asking for pardon."
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 to Objection 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 to Objection 2: This argument considers the question on the part of God's omnipotence, not on that of the circumstances of sin.
Reply to Objection 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.
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.
Objection 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.
Objection 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.
