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

“(Vict. Ant. e Cat. in Marc.) For since they unjustly accused the disciples not of transgressing the law, but the commands of the elders, He sharply confounds them, calling them hypocrites, as looking with reverence upon what was not worthy of it. He adds, however, the words of Isaiah the prophet, as spoken of them; as though He would say, As those men, of whom it is said, that they honour God with their lips, whilst their heart is far from him, in vain pretend to observe the dictates of piety, whilst they honour the doctrines of men, so ye also neglect your soul, of which ye should take care, and blame those who live justly.”
