Basil the Great
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.
(in Reg. fus. dis. int. 30.) Let not him that is chief be puffed up by his dignity, lest he fall away from the blessedness of humility, but let him know that true humility is the ministering unto many. As then he who attends many wounded and wipes away the blood from their wounds, least of all men enters upon the service for his own exaltation, much more ought he to whom is committed the care of his sick brethren as the minister of all, about to render an account of all, to be thoughtful and anxious. And so let him that is greatest be as the younger. (ad int. 31.). Again, it is meet that those who are in the chief places should be ready to offer also bodily service, after our Lord’s example, who washed His disciples’ feet. Hence it follows, And he that is chief, as he that doth serve. But we need not fear that the spirit of humility will be weakened in the inferior, while he is being served by his superior, for by imitation humility is extended.
