Gregory the Great, on Matt 12:43

“And when an unclean spirit is gone out of a man he walketh through dry places seeking rest, and findeth none.”

“(Mor. vii. 17.) For it often happens that the soul in the commencement of its progress is lifted up, and prides itself on its virtues, that it opens an entrance to the adversary who is raging against it, and who shews himself the more violent in breaking into it, by how much he was grieved at being cast out, though but for a short space.”
