II. Let him be strengthened in his faith by the holy associations of the place where he lives.
Make use, therefore, beloved brother, of these incontrovertible proofs of the Catholic Faith and support the preaching of the Evangelists by the testimony of the holy places in which you live. In your country is Bethlehem, in which the Light of Salvation sprang from the womb of the Virgin of the house of David, whom wrapped in swaddling clothes the manger of the crowded inn received. In your country was the Saviour's infancy announced by angels, adored by magi, sought by Herod through the death of many infants.
In your country was it that His boyhood grew, His youth ripened, and His true man's nature reached to perfect manhood by the increase of the body, not without food for hunger, not without sleep for rest, not without tears of pity, not without fear and dread: for He is one and the same Person, who in the form of God wrought great miracles of power, and in the form of a slave underwent the cruelty of the passion. This the very cross unceasingly says to you: this the stone of the sepulchre cries out, under which the Lord in human condition lay, and from which by Divine power He rose.
And when you approach the mount of Olivet, to venerate the place of the Ascension, does not the angel's voice ring in your ears, which says to those who were dumb-founded at the Lord's uplifting, “you men of Galilee, why do you stand gazing into heaven? This Jesus, Who was taken up from you into heaven, shall so come, as you saw Him going into heaven.”
