Bede the Venerable — as excerpted in the Catena Aurea on Mark 14:17-21

“(ubi sup.) Woe too to that man, to-day and for ever, who comes to the Lord’s table with an evil intent. For he, after the example of Judas, betrays the Lord, not indeed to Jewish sinners, but to his own sinning members. It goes on: Good were it for that man if he had never been born.”
