John Chrysostom
For this reason also the Evangelist marks the time that He may shew their iniquity overcome by nothing; for they came to Him at a time when He had wrought many miracles, when He had healed the sick by the touch of His hem. That the Scribes and Pharisees are here said to have come from Jerusalem, it should be known that they were dispersed through all the tribes, but those that dwelt in the Metropolis were worse than the others, their higher dignity inspiring them with a greater degree of pride.
Observe, how they are taken in their own question. They say not, ‘Why do they transgress the Law of Moses?’ but, the tradition of the elders; whence it is manifest that the Priests had introduced many new things, although Moses had said, Ye shall not add ought to the word which I set before you this day, neither shall ye take ought away from it; (Deut. 4:2.) and when they ought to have been set free from observances, then they bound themselves by many more; fearing lest any should take away their rule and power, they sought to increase the awe in which they were held, by setting themselves forth as legislators.
But the disciples now did not eat with washen hands, because they already despised all things superfluous, and attended only to such as were necessary; thus they accepted neither washing nor not washing as a rule, but did either as it happened. For how should they who even neglected the food that was necessary for them, have any care about this rite?
He desired to shew the great honour that ought to be paid to parents, and therefore attached both a reward and a penalty. But in this occasion the Lord passes over the reward promised to such as did honour their parents, namely, that they should live long upon the earth, and brings forward the terrible part only, namely, the punishment, that He might strike these dumb and attract others; And he that curseth father and mother, let him die the death; thus He shews that they deserved even death. For if ho who dishonours his parent even in word is worthy of death, much more ye who dishonour him in deed; and ye not only dishonour your parents, but teach others to do so likewise. Ye then who do not deserve even to live, how accuse ye my disciples? But how they transgress the commandment of God is clear when He adds, But ye say, Whoso shall say to his father or his mother, If in a gift, whatsoever thou mightest be profited by me.
