John 13:20

Verily, verily I say to you, that He that receives him whom I have sent, receives Me; and he that receives Me receives Him that sent Me. It is not clear how these words are connected with those which precede. First Chrysostom (Hom. 21), and Theophylact after him, refer them to the passion and cross of Christ, as though He were encouraging the apostles to imitate it. In other words: Fear not the persecutions, death, and crosses which you shall suffer in preaching My faith, for in this you will be following Me, suffering as My ambassadors, sent by Me and therefore by God the Father. Wherefore this suffering shall not bring ignominy on you, but glory. There is, however, no reference here to the sufferings of the apostles, but to their reception by the world.

Then again Cyril (bk. ix. ch. 12) thinks that Christ is showing the heinousness of Judas' treachery by means of an argument from its contrary, thus Just as he who receives and honours one sent by Me receives and honours Me, so, too, he who rejects him that I send offers a grievous insult not only to Me, but also to God who sent Me. Here, however, we must supply a great many things which Christ did not say.

Gaetano, Jansenius, and Ribera, with more probability, hold that Christ wished, at the close of His discourse on the washing of feet, to make some additional remarks by way of exhorting all the faithful to receive and treat with kindness the apostles sent to them, just as He had previously exhorted the apostles to be kind to the faithful. In this way He consoles the apostles too, whom He had bidden labour in offices of charity for the good of all. (Chrysostom, Homily 71.)

Lastly, Toletus thinks that this is connected with the example given in the washing of feet by Christ, in order that the apostles and the faithful may not excuse themselves from following it on the score that such an act lowers a man. For Christ Himself practised it, and in so doing rendered it honourable and noble. The meaning then is: He who entertains guests who are of the faith, especially apostles, and washes their feet, as it were receives Me who sent them, but he that receives Me receives also the Father who sent Me.

Christ, then, here teaches that offices of humility, such as the washing of feet, must be undertaken even by apostles and prelates, and not refused by them on the score of the dignity of their station, for by these works they shall become honourable as true imitators of Christ and His genuinely accredited agents. It was for this that St. Francis Xavier when, on his voyage to India, he used to make the beds of the sick people, cook their food, and give them their medicine, hearing the complaint made that such degrading occupations were not becoming to an Apostolic Legate as he was, answered that they were becoming to a disciple and -apostle of Christ, since Christ Himself underwent, and, as it were, ennobled them. For in the school of Christ humility alone ennobles and exalts, because it makes us like Christ our God and Lord. So says Tursellinus in his life of this Saint.

S. Charles Borromeo would, on an occasion of public supplication, go with his feet bare, a halter tied round his neck, carrying a cross. He used to discharge servile functions towards the poor, minister to those who were stricken with the plague, and fulfil every menial office; yet did he not by so doing derogate from his dignity as an Archbishop and a Cardinal, but rather enhanced it, and earned the name of "the Holy Cardinal." For as a carbuncle set in a gold ring increases its beauty, so does humility shed a lustre upon the insignia of high station.
