Catena Aurea · Matthäusevangelium 10
Think not that I am come to send peace on earth: I came not to send peace, but a sword. For I am come to set a man at variance against his father, and the daughter against her. mother, and the daughter in law against her mother in law. And a man’s foes shall be they of his own household.
(interlin.) Otherwise; He means, I am not come among men to strengthen their carnal affections, but to cut them off with the sword of the Spirit; whence it is rightly added, And a man’s foes are they of his household.
