John Chrysostom
Catena Aurea · Lukasevangelium 22
And there was also a strife among them, which of them should be accounted the greatest. And he said unto them, The kings of the Gentiles exercise lordship over them; and they that exercise authority upon them are called benefactors. But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve. For whether is greater, he that sitteth at meat, or he that serveth? is not he that sitteth at meat? but I am among you as he that serveth. But to the words of the exhortation He subjoins His own example, as it follows, For which is greater, he who sitteth at meat, or he that serveth? But I am among you, &c.
As if He says, Think not that thy disciple needs you, but that you do not need him. For I who need no one whom all things in heaven and earth need, have condescended to the degree of a servant.
