There are no words of the Gospel, my dear brethren, more frequently used in the church of God than these. You often hear them from the lips of the priest, but perhaps you do not remember when. They are more familiar to you in Latin than in English. {76} The moment when they are said is that when the greatest of all gifts is about to be given to you. It is just before the giving of Holy Communion. The priest, turning to you with the ciborium in his hand, raises one of the sacred particles from it, and shows it to you, saying, _Ecce Agnus Dei_--which means, "Behold the Lamb of God"--_ecce qui tollis peccata mundi_, "Behold, he who taketh away the sins of the world." The church has put the words in the mouth of the priest at this time, when he distributes Holy Communion, because he is then showing Christ to the faithful. And she puts them in the Gospel of today, because on this day, the octave of the great feast which we celebrated last Sunday, she commemorates what we may call our Lord's second Epiphany after his hidden life of thirty years, when St. John the Baptist, his great precursor, taking the place of the star which showed him to the wise men, showed him to those who were to become his disciples, and who were to accompany him in that ministry of three years upon which he was about to enter. As St. John took the place of the star, so the Catholic priest now takes the place of St. John. He has now to show Christ to the world, and especially to the faithful. And St. John, in his humility and self-concealment, has set an example to him which he should try to copy, and which a good priest does try to copy. That is, he tries to show our Lord to the people and to keep himself in the background; he tries to bring the faithful to his Master and theirs, not to himself. He desires that they should see in all that he does not his own power or gifts, but the grace of God, by which alone he can do them any good; that they should not be drawn to him, but to the Lamb of God, who alone can take away their sins. {77} And what the good priest does you also, my brethren, should do. You should not think of the priest, but of Him whom the priest represents, and in whose power he acts. And especially should you take care to do this in those sacramental acts which the priest does more particularly in the name of God; that is, when he celebrates Holy Mass, baptizes, hears confessions, or gives Holy Communion. For, in truth, it is not he who does these things, but our Lord Jesus Christ. He, the Lamb of God, is the true priest. He who instituted the sacraments also is the one who confers them. Remember this when you receive them. When you go to the altar-rail for Holy Communion, and when the priest holds up the sacred Host before you, saying, _Ecce Agnus Dei, ecce qui tollit peccata mundi_, think not of the priest, of his virtues or his faults, but of the immaculate Lamb of God, who is coming to you, a poor sinner.
