Bede the Venerable — as excerpted in the Catena Aurea on Mark 2:13-17

“(in Marc. i. 12) The persons here called publicans are those who exact the public customs, or men who farm the customs of the exchequer or of republics; moreover, those also, who follow after the gain of this world by business, are called by the same name. They who had seen that the publican, converted from his sins to better things, had found a place of pardon, even for this reason themselves also do not despair of salvation. And they come to Jesus, not remaining in their former sins, as the Pharisees and Scribes complain, but in penitence, as the following words of the Evangelist shew, saying, For there were many who followed him. For the Lord went to the feasts of sinners, that he might have an opportunity of teaching them, and might set before his entertainers spiritual meats, which also is carried on in mystical figures. For he who receives Christ into his inward habitation is fed with the highest delights of overflowing pleasures. Therefore the Lord enters willingly, and takes up His abode in the affection of him who hath believed on Him; and this is the spiritual banquet of good works, which the rich cannot have, and on which the poor feast.”
