Matthew 12:27

(Quæst. Ev. i. 5.) Whence the sense might be this, If I by Beelzebub vast out dæmons, then, according to your own opinion, the kingdom of God is come upon you, for the kingdom of the Devil, being thus divided against itself, cannot stand. Thus calling that the kingdom of God, in which the wicked are condemned, and are separated from the faithful, who are now doing penitence for their sins.

And they are worthily appointed judges over them, to whom Christ is found to have given that power over the dæmons, which it was denied that He had. If then the disciples work by Christ, and Christ by the Spirit of God, already is the kingdom of God transferred to the Apostles through the office of the Mediator.

But if ye think, ye Scribes and Pharisees, that the dæmons depart out of the possessed in obedience to their Prince, that men may be imposed upon by a concerted fraud, what can ye say to the healing of diseases which the Lord also wrought? It is something more if ye assign to the dæmons even bodily infirmities, and the signs of spiritual virtues. He alludes, as is His manner, under the name children of the Jews, either to the exorcists of that race, or to the Apostles who are by race of that nation. If He means the exorcists who by the invocation of God cast out dæmons, He thus constrains the Pharisees by a wise enquiry to confess that their work was of the Holy Spirit. If, He would say, the casting out of the dæmons by your children is imputed to God, and not to dæmons, why should the same work wrought by Me not have the same cause? Therefore shall they be your judges, not by authority but by comparison, they ascribe the casting out of the dæmons to God, you to the Prince of the dæmons. But if it is of the Apostles also that this is said, (and so we should rather take it,) then they shall be their judges, for they shall sit on twelve thrones judging the twelve tribes of Israel. For the kingdom of God denotes Himself, of whom it is written in another place, The kingdom of God is among you; (Luke 17:21) and, There standeth one in the midst of you whom ye know not. (John 1:26) Or surely that kingdom which both John and the Lord Himself had preached above, Repent ye, for the kingdom of heaven is at hand. (Mat. 3:2 4:17.) There is also a third kingdom of the Holy Scripture which shall be taken from the Jews, and be given to a nation that brings forth the fruit thereof.

This then being the first refutation, the next after it is that which relates to the disciples. For not always in one way only, but also in a second and third, He solves their objections, being minded most abundantly to silence their shamelessness. Which sort of thing He did also with respect to the Sabbath, bringing forward David, the priests, the testimony that saith, "I will have mercy, and not sacrifice," the cause of the Sabbath, for which it was ordained; "for the Sabbath," saith He," was for man." This then He doth in the present case also: where after the first He proceeds to a second refutation, plainer than the former. "For if I," saith He, "by Belezebub cast out devils, by whom do your sons cast them out?" See here too His gentleness. For He said not, "my disciples," nor, "the apostles," but "your sons;" to the end that if indeed they were minded to return to the same nobleness with them, they might derive hence a powerful spring that way; but if they were uncandid, and continued in the same course, they might not thenceforth be able to allege any plea, though ever so shameless. But what He saith is like this, "By whom do the apostles cast them out?" For in fact they were doing so already, because they had received authority from Him, and these men brought no charge against them; their quarrel not being with the acts, but with the person only. As then it was His will to show that their sayings arose only from their envy against Him, He brings forward the apostles; thus: If I so cast them out, much more those, who have received their authority from me. Nevertheless, no such thing have ye said to them. How then bring ye these charges against me, the author of their doings, while acquitting them of the accusations? This, however, will not free you from your punishment, rather it will condemn you the more. […]

Or, because the Apostles well knew within their own conscience that they had learnt no evil art from Him.
