Pseudo-Chrysostom
Catena Aurea · Markusevangelium 3
And he called them unto him, and said unto them in parables, How can Satan cast out Satan? And if a kingdom be divided against itself, that kingdom cannot stand. And if a house be divided against itself, that house cannot stand. And if Satan rise up against himself, and be divided, he cannot stand, but hath an end. No man can enter into a strong man’s house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house. Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation: Because they said, He hath an unclean spirit.
(Vict. Ant. e Cat. in Marc.) He says indeed, that blasphemy concerning Himself was pardonable, because He then seemed to be a man despised and of the most lowly birth, but, that contumely against God has no remission. Now blasphemy against the Holy Ghost is against God, for the operation of the Holy Ghost is the kingdom of God; and for this reason, He says, that blasphemy against the Holy Ghost cannot be remitted. Instead, however, of what is here added, But will be in danger of eternal damnation, another Evangelist says, Neither in this world, nor in the world to come. By which is understood, the judgment which is according to the law, and that which is to come. For the law orders one who blasphemes God to be slain, and in the judgment of the second law he has no remission. nHowever, he who is baptized is taken out of this world; but the Jews were ignorant of the remission which takes place in baptism. He therefore who refers to the devil miracles, and the casting out of devils which belong to the Holy Ghost alone, has no room left him for remission of his blasphemy. Neither does it appear that such a blasphemy as this is remitted, since it is against the Holy Ghost. Wherefore he adds, explaining it, Because they said, He hath an unclean spirit.
