Matthew 12:43

(Quæst. Ev. i. 8.) So that in these words the Lord signifies that some shall so believe, as not to have strength for the work of continence, and shall return to the world. He taketh unto him other seven, is to be understood that when any has fallen from righteousness, he shall also have hypocrisy. For the lust of the flesh being cast out of its wonted works by penitence, when it finds not any delights in which it may rest, returns the more greedily, and again takes possession of the soul, if carelessness has ensued, and there has not been introduced as the dweller in the cleansed abode the word of God in sound doctrine. And as he will not only have the seven vices which are the contraries of the spiritual virtues, but will hypocritically feign that he has the virtues, therefore his old lust, taking to itself seven other worse, that is, this seven-fold hypocrisy, returns to him so as to make the last state of that man worse than the former.

The law which was given later intervened, casting out the unclean spirit dwelling in the hearts of the elect people. It kept that spirit away as if it were surrounding the people with its protective power. Going out from there, the spirit wandered among the nations in the deserts and arid places, leaving behind its old home, so that it might rest in these places until the day of judgment and not in a troubled dwelling [as Israel provided].But when God's grace was imparted afresh to the nations, flowing as a living fountain through the cleansing water [of baptism], there was no place for the spirit to continue living among them, and indeed he had no rest with them. After reconsidering its present situation, the spirit believed the best thing to do was to return to the house from which it had come. That house, having been cleaned out through the law, decorated with the proclamation of the prophets and finally prepared by the coming of Christ, was found to be vacant. The custodian of the law had left—because the whole law [was valid] until John—and those living there did not receive Christ. Also, there was no inhabitant in the dwelling, and it had been left unguarded. Because of the concern of those who were living there before, the place had been kept clean and adorned for the incoming dweller. Then seven spirits even more evil entered in—as many as there were the gifts of grace offered by Christ which God's all-embracing wisdom had placed there with a sevenfold glory. In this way the possession of wicked spirits was as great as the possession of grace would have been. Thus "the last state of that man becomes worse than the first," because the unclean spirit left the house for fear of the law but now returns with a vengeance because of the grace that was rejected.

He calls the hearts of the Gentiles, dry places, as lacking all the moisture of wholesome waters, that is of the holy Scriptures, and of spiritual gifts, and strangers to the pouring in of the Holy Spirit. The Devil supposed he should have rest for ever among the Gentiles, but it is added, and findeth none, because when the Son of God appeared in the mystery of His incarnation, the Gentiles believed.

Some suppose that this place is spoken of heretics, because the unclean spirit who dwelt in them before when they were Gentiles, is cast out before the confession of the true faith; when after they went over to heresy, and garnished their house with feigned virtues, then it is that the Devil, having taken to him other seven evil spirits, returns and dwells in them; and their last state becomes worse than their first. And indeed heretics are in a much worse condition than the Gentiles; for in the heretics was a hope of faith, in the Gentiles a war of discord. Yet though this exposition has a plausibility and a show of learning, I am doubtful of its truth. For by the concluding words of this, whether it be parable or example, Titus shall it he to this evil generation, we are compelled to refer it, not to heretics, or to men in general, but to the Jewish people. So the context of the passage may not shift about loosely and vaguely, and be like unmeaning speeches, but may be consistent with itself from first to last. The unclean spirit then went out from the Jews when they received the Law; and being cast out of the Jews, he walked through the wilderness of the Gentiles; as it follows, He walketh through dry places seeking rest. And when they believed on the Lord, the Devil, finding no place among the nations, said, I will return into my house whence I came out; I have the Jews from whom I formerly departed. And when he is come, he findeth it empty, swept, and garnished. For the temple of the Jews was empty, and had not Christ to dwell therein, He having said, Arise, let us go hence. (John 14:31) Seeing then they had not the protection of Angels, and were burdened with the useless observances of the Law, and the traditions of the Pharisees, the Devil returns to his former dwelling, and, taking to him seven other dæmons, inhabits it as before. […]

When therefore He had condemned them, having proved most amply that they were sinning inexcusably, and that their disobedience arose from their own perverseness not from their Teacher's inability, and when He had demonstrated this as well by many other arguments, as also by the Ninevites, and by the queen: then He speaks also of the punishment that should overtake them, darkly indeed, yet He doth speak of it, interweaving an intense fear in His narration. "For when," saith He, "the unclean spirit is gone out of the man, he walketh through dry places, seeking rest; and finding none, he saith, I will return to my house from whence I came out; and when he is come, he findeth it empty, and swept and garnished. Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there, and the last state of that man is worse than the first. Even so shall it be also unto this generation." By this He signifies, that not only in the world to come, but here too they should suffer most grievously. For since He had said, "The men of Nineveh shall rise up in judgment, and shall condemn this generation;" lest, on account of the postponement of the time, they should despise and grow more careless, by this He brings His terror close upon them. Wherewith the prophet Hosea likewise threatening them said, that they should be "even as the prophet that is beside himself, the man that is carried away by a spirit;" that is to say, as the madmen, and distracted by evil spirits, even the false prophets. For here, by "a prophet that is beside himself," he means the false prophet, such as are the augurs. […]
