Cyprian of Carthage
Catena Aurea · Lukasevangelium 11
And as he spake, a certain Pharisee besought him to dine with him, and he went in, and sat down to meat. And when the Pharisee saw it, he marvelled that he had not first washed before dinner. And the Lord said unto him, Now do ye Pharisees make clean the outside of the cup and the platter; but your inward part is full of ravening and wickedness. Ye fools, did not he that made that which is without make that which is within also? But rather give alms of such things as ye have; and, behold, all things are clean unto you. But woe unto you, Pharisees! for ye tithe mint and rue and all manner of herbs, and pass over judgment and the love of God: these ought ye to have done, and not to leave the other undone. Woe unto you, Pharisees! for ye love the uppermost seats in the synagogues, and greetings in the markets. Woe unto you, Scribes and Pharisees, hypocrites! for ye are as graves which appear not, and the men that walk over them are not aware of them.
(de Op. et Eleem.) The Merciful bids us to shew mercy; and because He seeks to save those whom He has redeemed at a great price, He teaches that they who have been defiled after the grace of baptism may again be made clean.
