Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 23
But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments, And love the uppermost rooms at feasts, and the chief seats in the synagogues, And greetings in the markets, and to be called of men, Rabbi, Rabbi. But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren. And call no man your father upon the earth: for one is your Father, which is in heaven. Neither be ye called masters: for one is your Master, even Christ. But he that is greatest among you shall be your servant. And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.
Every substance breeds in itself that which destroys it, as wood the worm, and garments the moth; so the Devil strives to corrupt the ministry of the Priests, who are ordained for the edification of holiness, endeavouring that this good, while it is done to be seen of men, should be turned into evil. Take away this fault from the clergy, and you will have no further labour in their reform, for of this it comes that a clergyman who has sinned can hardly perform penance. Also the Lord here points out the cause why they could not believe in Christ, because nearly all they did was in order to be seen of men; for he whose desire is for earthly glory from men, cannot believe on Christ who preaches things heavenly. I have read one who interprets this place thus. In Moses’ seat, that is, in the rank and degree instituted by Moses, the Scribes and Pharisees are seated unworthily, forasmuch as they preached to others the Law which foretold Christ’s coming, but themselves did not receive Him when come. For this cause He exhortsthe people to hear the Law which they preached, that is, to believe in Christ who was preached by the Law, but not to follow the Scribes and Pharisees in their disbelief of Him. And He shews the reason why they preached the coming of Christ out of the Law, yet did not believe on Him; namely, because they did not preach that Christ should come through any desire of His coming, but that they might be seen by men to be doctors of the Law.
