12:25. And Jesus knowing their thoughts, said to them: Every kingdom divided against itself shall be made desolate: and every city or house divided against itself shall not stand.
12:26. And if Satan cast out Satan, he is divided against himself: how then shall his kingdom stand?
12:27. And if I by Beelzebub cast out devils, by whom do your children cast them out? Therefore they shall be your judges.

12:31. Therefore I say to you: Every sin and blasphemy shall be forgiven men, but the blasphemy of the Spirit shall not be forgiven.
The blasphemy of the Spirit… The sin here spoken of is that blasphemy, by which the Pharisees attributed the miracles of Christ, wrought by the Spirit of God, to Beelzebub the prince of devils. Now this kind of sin is usually accompanied with so much obstinacy, and such wilful opposing the Spirit of God, and the known truth, that men who are guilty of it, are seldom or never converted: and therefore are never forgiven, because they will not repent. Otherwise there is no sin, which God cannot or will not forgive to such as sincerely repent, and have recourse to the keys of the church.
12:32. And whosoever shall speak a word against the Son of man, it shall be forgiven him: but he that shall speak against the Holy Ghost, it shall not be forgiven him neither in this world, nor in the world to come.
