Pseudo-Chrysostom — as excerpted in the Catena Aurea on Mark 7:1-13

“(Vict. Ant. e Cat. in Marc.) Notwithstanding the existence of such a divine law, and the1 threats against such as break it, ye lightly transgress the commandment of God, observing the traditions of the Elders. Wherefore there follows, But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; understand, he will be freed from the observation of the foregoing command. Wherefore it continues, And ye suffer him no more to do ought for his father or his mother.”
