John Chrysostom, Homilies on the Gospel of Matthew, Homily 65 (on Matthew 20:25-28)
And not as before, so now also doth He check them. For whereas before He brings little children into the midst, and commands to imitate their simplicity and lowliness; here He reproves them in a sharper way from the contrary side, saying, �The princes of the Gentiles exercise dominion over them, and their great ones exercise authority upon them, but it shall not be so among you; but he that will be great among you, let this man be minister to all; and he that will be first, let him be last of all;� showing that such a feeling as this is that of heathens, I mean, to love the first place. For the passion is tyrannical, and is continually hindering even great men; therefore also it needs a severer stripe. Whence He too strikes deeper into them, by comparison with the Gentiles shaming their inflamed soul, and removes the envy of the one and the arrogance of the other, all but saying, �Be not moved with indignation, as insulted. For they harm and disgrace themselves most, who on this wise seek the first places, for they are amongst the last. For matters with us are not like matters without. �For the princes of the Gentiles exercise dominion over them,� but with me the last, even he is first.�
�And in proof that I say not these things without cause, by the things which I do and suffer, receive the proof of my sayings. For I have myself done something even more. For being King of the powers above, I was willing to become man, and I submitted to be despised, and despitefully entreated. And not even with these things was I satisfied, but even unto death did I come. Therefore,� He saith, �Even as the Son of Man came not to be ministered unto, but to minister, and to give His life a ransom for many.� �For not even at this did I stop,� saith He, �but even my life did I give a ransom; and for whom? For enemies. But thou if thou art abused, it is for thyself, but I for thee.�
Be not then afraid, as though thine honor were plucked down. For how much soever thou humblest thyself, thou canst not descend so much as thy Lord. And yet His descent hath become the ascent of all, and hath made His own glory shine forth. For before He was made man, He was known amongst angels only; but after He was made man and was crucified, so far from lessening that glory, He acquired other besides, even that from the knowledge of the world.
Fear not then, as though thine honor were put down, if thou shouldest abase thyself, for in this way is thy glory more exalted, in this way it becomes greater. This is the door of the kingdom. Let us not then go the opposite way, neither let us war against ourselves. For if we desire to appear great, we shall not be great, but even the most dishonored of all.
Seest thou how everywhere He urges them by the opposite things, giving them what they desire? For in the preceding parts also we have shown this in many instances, and in the cases of the covetous, and of the vain-glorious, He did thus. For wherefore, He saith, dost thou give alms before men? That thou mayest enjoy glory? Thou must then not do so, and thou shall surely enjoy it. Wherefore dost thou lay up treasures? That thou mayest be rich? Thou must then not lay up treasures, and thou shalt be rich. Even so here too, wherefore dost thou set thy heart on the first places? That thou mayest be before others? Choose then the last place, and then thou wilt enjoy the first. So that if it be thy will to become great, seek not to become great, and then thou wilt be great. For the other is to be little.
