Ver. 32. Whosoever, &c. It was their duty to have a knowledge of the Holy Ghost, and they obstinately refused to admit what was clear and manifest. Though they were ignorant of the divinity of Jesus Christ, and might take him to be merely the son of a poor artizan, they could not be ignorant that the expelling of demons, and miraculous healing of all diseases, were the works of the Holy Ghost. If, therefore, they refused to do penance for the insult offered to the Spirit of God, in the person of Christ, they could not hope to escape condign punishment. (St. Chrysostom, hom. xlii). — Against the Son of man, it shall be forgiven him; i.e. they who for want of sufficient instruction, were invincibly ignorant that Christ was God, might more easily be brought to the true knowledge and faith of Christ, and so receive forgiveness of their sins: but if he shall speak against the Holy Ghost, i.e. against the Spirit of God in Christ, and shall oppose the known truth, by attributing to the devil that doctrine, and those miracles, which evidently were from the Spirit and the hand of God, that sin shall never be forgiven him. But how is this consistent with the Catholic doctrine and belief, that there is no sin any man commits of which he may not obtain pardon in this life? To this I answer, that in what manner soever we expound this place, it is an undoubted point of Christian faith, that there is no sin which our merciful God is not ready to pardon; no sin, for the remission of which, God hath not left a power in his Church, as it is clearly proved by those words, Whose sins you shall forgive, they are forgiven them, &c. St. Chrysostom therefore expounds these words, shall not be forgiven them, to imply no more, than shall scarcely, or seldom be forgiven; that is, it is very hard for such sinners to return to God, by a true and sincere repentance and conversion; so that this sentence is like to that (Matthew xix. 26.) where Christ seems to call it an impossible thing for a rich man to be saved. In the same place St. Chrysostom tells us, that some of those who had blasphemed against the Holy Ghost, repented, and had their sins forgiven them. St. Augustine, by this blasphemy against the Spirit, understands the sin of final impenitence, by which an obstinate sinner refuseth to be converted, and therefore lives and dies hardened in his sins. (Witham) — Nor in the world to come. From these words St. Augustine (De Civ. lib. xxi. chap. 13.) and St. Gregory (Dial. iv, chap. 39.) gather, that some sins may be remitted in the world to come; and consequently that there is a purgatory, or a middle place. (Challoner) — St. Augustine says these words would not be true, if some sins were not forgiven in the world to come; and St. Gregory says, we are to believe from these words in the existence of the fire of purgatory, to expiate our smaller offences, before the day of judgment. St. Isidore and Ven. Bede say the same. St. Bernard, speaking of heretics, says, they do not believe in purgatory: let them then inquire of our Saviour, what he meant by these words. — It is well known that Ven. Bede, on his death-bed, bestowed several small tokens to the monks who were present, that they might remember to pray for his soul in the holy sacrifice of the mass. (Haydock)
