John 1:19

And this is the witness of John, &c. John the Baptist often bare witness to Jesus, that He was the Messias, or the Christ, both before and after His baptism. John the Evangelist therefore, omitting in this place the testimony which the Baptist bore to Jesus before His baptism, which had been related by the three other Evangelists, gives his testimony concerning Him after he had baptised Him. For this testimony was public, judicial, and most celebrated. It had been judicially demanded by the chief priests and magistrates, and had been received by them through the ambassadors whom they sent to John. The reason of this embassy was because the chief priests saw John leading in the desert an angelic life, preaching with great power, baptising, and moving men to repentance, as none of the other prophets had done. The chief priests thought therefore that it was their duty to ask him who he was, especially because they knew that the sceptre had passed from Judah to Herod, and the seventy weeks of Daniel being completed, the coming of Messias must be nigh at hand. Wherefore, suspecting that John was the Messias, they ask him, Who art thou?

S. Chrysostom gives another reason that they asked out of envy and hatred of Jesus, in order that they might show that Jesus was not the Messiah. They would have preferred to bestow the title upon John. They disliked John's preferring Jesus to himself, and calling Him the Messias or Christ. But although there might be some envy mingled with it, the true reason was, as I have said, that it was the counsel of God so to exalt John, that the chief priests might be driven to ask him whether he were the Christ or not, that being asked he might authoritatively answer that which was the truth, namely, that not he, but Jesus, was the Messias, and that, being convicted by this testimony of John, they might be compelled either to receive Jesus as the Messias or to be without excuse.

Who art thou? The chief priests appear tacitly at least to have inquired of John, whether he were the Christ or not; for John replies, I am not the Christ.

Moreover, they were aware that John was the son of the priest Zacharias, and therefore a priest himself. When therefore they say, Who art thou? they ask virtually, What office hast thou received from God? With what object has God sent thee to preach and baptize? For God was wont to commit greater offices to priests.

Tropologically, let every one often ask himself, Who art Thou? Firstly, as regards our substance. Listen to thy conscience making answer to thyself the name of God my Creator is, I AM THAT I AM (Exo 3:14) My name therefore as a creature is "I am that am not," because I am nothing of myself, but out of my nothingness have been brought forth by God, and made a man. Wherefore my body and soul are not my own, but God's, who has given them, or rather lent them, to me. As S. Francis was wont to say, "Who art Thou, Lord? Who am I? Thou art an abyss of wisdom and long-suffering, and all goodness. I am an abyss of ignorance, weakness, of all evil and wretchedness. Thou art an abyss of being, I of nothingness." So when Christ appeared to S. Catherine of Sienna, He said, "Blessed art thou if thou knowest who I am, and who thou art. I am He who is, thou art she who is not."

Secondly, as to quality. Who? that is, of what sort art thou? Answer, As regards my body, I am weak, miserable, and wretched. As to my soul, as regards my reason, I am like unto the angels. As regards my sensual appetite, and concupiscence, I am like the brutes. Therefore I will follow my reason, and so become assimilated to the angels.

Thirdly, as regards relation. Who? that is, whose son art thou? Reply, I am the son of Adam, the first sinner, and therefore being born in sin, I am living in sin, and must die in sin, unless the grace of Christ rescue me from my sins, and sanctify and save me.

Fourthly, as regards employment. Who art thou? what trade or profession art thou? I am a carpenter, a baker, a governor, a shepherd, a lawyer. See then that thou exercise thyself in thy calling, whatsoever it be, as the law of God requires, namely, in such wise that thou live soberly, righteously, and godly in this present world, looking for the blessed hope, and the coming of the glory of the great God, that thou mayest so pass through things temporal, that thou lose not, but gain the things eternal. Work, study, live for eternity. As S. Bernard was wont often to say to himself, "Bernard, tell me, wherefore art thou here?" And with this goad, as it were, he stirred himself up to zeal for all virtues.

Fifthly, as regards suffering. Who art thou? that is to say, what dost thou suffer? Reply, In the body I suffer hunger, thirst, disease, continual afflictions, so that there is scarcely the smallest space of time: in which I have not many things to bear. As regards my soul, I have far greater and more bitter afflictions, griefs, and anguish, anxieties, sorrows, angers, indignation, darkness, fear, &c., so that I seem to be, as it were, a mark at which all afflictions hurl their darts, and thrust me through with their arrows. Be thou therefore a very adamant of patience, that thou mayest patiently and generously endure all things, and win the everlasting crown of patience in heaven.

Sixthly, as regards place. Who? that is, where art thou? Answer, I am on earth, placed between heaven and hell, in such wise, that if I live holily, I may pass to heaven, if wickedly, to hell. Live therefore carefully, warily, and holily, that not hell, but heaven may receive thee, when this short mortal life is over.

Seventhly, as regards time. Who art thou? When wast thou born? How long hast thou lived? When shalt thou die? Answer, Born yesterday, today I live, to-morrow I die. "For we are of yesterday, and know nothing; all our days upon the earth are but a shadow" (Job viii. 9). Therefore despise all things temporal, which fly past as a bird doth. Love and covet heavenly things, which endure forever with God and the angels. So shalt thou, being eternal, be happy eternally, and abide in everlasting delights. For as S. Gregory says, "That we may be eternal, and happy eternally, let us imitate eternity. And this is to us a great eternity, even the imitation of eternity."

Lastly, as regards posture and clothing. Who art thou? that is, what posture, or clothing hast thou? Reply, I stand, I sit, I lie. I wear the habit of a Christian, a priest, a bishop, a religious. Take heed then that thou live conformably to thy habit. For it is not the habit which makes the Christian, or the monk, but purity of life, humility, charity.
