The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 21
Of Saint Patrick's Vision.
And a short space of time being passed, the while he was settled in his lather's house, he beheld in a vision of the night a man of comely garb and countenance, bearing many letters as if from Ireland, and holding out to him one of them for him to read—which taking, he read, and found therein thus written: "THIS IS THE VOICE OF THE IRISH." But when he would have continued to read, he seemed in the spirit to hear the Irish infants which were yet unborn crying unto him with a loud voice, "O holy youth Patrick! we beseech thee come unto us, and abide with us, and release us!" And Patrick, being pierced therewith in his heart, could not finish the letter; but awaking, he gave infinite thanks to God, for he was assured by the vision that the Lord had set him apart, even from his mother's womb, had by His grace called him to convert and to save the Irish nation, which seemed to desire his presence among them. And on this he consulted the angel of great counsel, and through the angel Victor he received the divine command that, quitting his father and his country, he should go unto France, there to learn the doctrine and the discipline of the Christian faith.
