Bede the Venerable
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.
(in loc.) Or, the sheep are works of purity and piety, and they sell the sheep, who do works of piety to gain the praise of men. They exchange money in the temple, who, in the Church, openly devote themselves to secular business. And besides those who seek for money, or praise, or honour from Holy Orders, those too make the Lord’s house a house of merchandize, who do not employ the rank, or spiritual grace, which they have received in the Church at the Lord’s hands, with singleness of mind, but with an eye to human recompense.
