Then he goes, and takes 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 wicked generation.
All Commentaries on Matthew 12:45 Go To Matthew 12
Augustine of Hippo
AD 430
When there is forgiveness of sins through the sacraments, the house is cleaned; but the Holy Spirit must be a necessary inhabitant. And the Holy Spirit inhabits only those who are humble of heart, for God says, “Upon whom will my Spirit rest?” And he answers the question: “Upon the one who is humble and quiet and who fears my word.” Therefore, when he is the inhabitant, he fills up, rules, acts, deters from evil, inspires one to do good and tempers justice with sweetness, so that one may do good with the love of an upright heart and not with the fear of punishment. But once that unclean spirit that made you evil has gone out of you, that is, from your mind, when your sins have been forgiven, it roams through dry places in search of a resting place. Finding none, the unclean spirit returns to his house, where he finds everything clean and in order. Then he takes with him seven other spirits more evil than himself; and the last state of that person becomes worse than the first. He takes with him seven other spirits. What is meant by “seven other spirits”? Is the unclean spirit itself sevenfold? What does this mean? By seven the whole group is signified. The whole spirit went away, the whole spirit came back; and would that only one spirit returned! What does it mean: “He takes with him seven other spirits”? Those spirits you did not have when you were evil, you will have unexpectedly when you are good. Listen carefully while I explain as best I can. By a sevenfold operation the Holy Spirit is committed to our care, so that we may have the “spirit of wisdom and understanding, counsel and fortitude, knowledge and true godliness, and fear of God.” Arrayed on the opposite side of this sevenfold good is the sevenfold evil: the spirit of stupidity and error, the spirit of foolhardiness and cowardice, the spirit of ignorance and impiety, and the spirit of pride against the fear of God. These are seven evil spirits. What are the seven other spirits even more evil? The seven other spirits even more evil are found in hypocrisy. One evil spirit is the spirit of stupidity, the other worse evil is the pretense of wisdom. The evil spirit of error, the other worse evil, is the pretense of truth. The evil spirit of foolhardiness, the other worse evil, is the pretense of counsel. The evil spirit of cowardice, the other worse evil, is the pretense of fortitude. The evil spirit of ignorance, the other worse evil, is the pretense of knowledge. The evil spirit of impiety, the other worse evil, is the pretense of piety. The evil spirit of pride, the other worse evil, is the pretense of fear. Seven were intolerable. Who will tolerate fourteen? Necessarily, therefore, when the pretense of truth is added to malice, the last state of that person becomes worse than the first. ..
