Theophylact of Ohrid
Catena Aurea · Markusevangelium 11
And they come to Jerusalem: and Jesus went into the temple, and began to cast out them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves; And would not suffer that any man should carry any vessel through the temple. And he taught, saying unto them, Is it not written, My house shall be called of all nations the house of prayer? but ye have made it a den of thieves. And the Scribes and Chief Priests heard it, and sought how they might destroy him: for they feared him, because all the people was astonished at his doctrine.
But if a man by sinning gives up to the devil the grace and purity of baptism, he has sold his Dove, and for this reason is cast out of the temple. There follows, And would not suffer that any man should carry any vessel through the temple.
