Chrysostom, the ‘Golden Mouthed,’ on Matthew 23:11&12…
But he who is greatest among you shall be your servant. And whoever exalts himself will be humbled, and he who humbles himself will be exalted.
“For nothing is equal to the practice of modesty, wherefore He is continually reminding them of this virtue, both when He brought the children into the midst, and now. And, when on the mount, beginning the beatitudes, He began from hence. And in this place, He plucks it up by the roots hereby, saying, ‘He that abaseth himself shall be exalted.’ ”
