Catena Aurea · Johannesevangelium 2
And found in the temple those that sold oxen and sheep and doves, and the changers of money sitting: And when he had made a scourge of small cords, he drove them all out of the temple, and the sheep, and the oxen; and poured out the changers’ money, and overthrew the tables; And said unto them that sold doves, Take these things hence; make not my Father’s house an house of merchandise. And his disciples remembered that it was written, The zeal of thine house hath eaten me up.
To take the passage mystically, God enters His Church spiritually every day, and marks each one’s behaviour there. Let us be careful then, when we are in God’s Church, that we indulge not in stories, or jokes, or hatreds, or lusts, lest on a sudden He come and scourge us, and drive us out of His Church.
