Bede the Venerable
Catena Aurea · Matthäusevangelium 8
And when Jesus was come into Peter’s house, he saw his wife’s mother laid, and siek of a fever. And he touched her hand, and the fever left her: and she arose, and ministered unto them.
(in loc.) Figuratively; Peter’s house is the Law, or the circumcision, his mother-in-law the synagogue, which is as it were the mother of the Church committed to Peter. She is in a fever, that is, she is sick of zealous hate, and persecutes the Church. The Lord touches her hand, when He turns her carnal works to spiritual uses.
