Mark 7:6

(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.

He beats back the vain words of the Pharisees with His arguments, as men drive back dogs with weapons, by interpreting Moses and Isaiah, that we too by the word of Scripture may conquer the heretics, who oppose us; wherefore it goes on: (Isa. 29:13) Well hath Esaias prophesied of you hypocrites; as it is written, This people honoureth me with their lips, but their heart is far from me.
