Origen
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.
Or otherwise; And if one minister the divine word, knowing that it is Christ that makes it to be fruitful, such a one professes himself a minister and not a master; whence it follows, He that is greatest among you, let him be your servant. As Christ Himself, who was in truth our Master, professed Himself a minister, saying, I am in the midst of you as one that ministers. (Luke 22:27.) And well does He conclude this prohibition of all vain-glory with the words, And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.
