After this time he tried again to reach Scotland, to which he was drawn every hour by ties of blood and affection; and at last he embarked on a vessel bound to a port very near his own native town. He found his father and mother still living and they rejoiced mightily to see him, for to them he was as one who had returned from the dead. In place of the boy they had lost there appeared a tall and finely built man with a face hardened by toil but made noble by thought and suffering. And they had a feast to celebrate his return and wept for joy because they had their son again.
But the dreams that Saint Patrick had experienced in Ireland once more came to him, and in his sleep he heard the Heavenly voice telling him that he had been rescued from slavery for no mean or ordinary purpose, but must go again into Ireland as a priest, and teach the Christian religion to the savage Irish clans. So Saint Patrick knew that he must return to Ireland, and, bidding his parents farewell, he departed to become a priest in preparation for the labor that lay before him.
He studied to such purpose that he became a Bishop, celebrated for his learning and famous among the clergymen; and when this was accomplished he set sail once more for Ireland with a retinue of priests and clergymen accompanying him. But although he was going to a savage land where he had already experienced much bitterness and sorrow, he went unarmed, and among his entire company there was not so much as a single sword or lance.
He came to a place called Strangford Lough and there landed with his band of missionaries. The Irish fled at his approach, for they feared that the tall man who bore the cross was the leader of an invading army, and also that he possessed the arts of magic by which he would do injury to them.
Many of the Irish believed in the religion of the Druids—a strange faith that brought in the magic arts and endeavored to teach above all other things that a man's soul when he dies enters another human body. This belief was widely established throughout the world, and it is true that many persons beside the Druids believed in it; but the Druids had other beliefs that were cruel and dangerous. They were said to perform human sacrifices and their priests to practise black magic. These priests wore about their necks the "serpent's egg," a ball formed of the spittle of many poisonous snakes; they knew many strange things about animals and plants and held the oak tree to be sacred. For this reason they worshipped in oaken groves, and considered the mistletoe that grew around oak trees to have divine powers. It was cut by white-robed priests with golden knives in an impressive ceremony.
It can readily be seen that such people, who believed in such a faith, would not easily become Christians. Their priests were clever and knew how to place the stamp of fear and wonder on their minds. And—in company with all other people in those days—the Irish distrusted outsiders and were far more ready to believe them coming in treachery than in friendship.
When Saint Patrick and his followers set foot in Ireland it was the time of a great religious festival in which no lights were allowed to be lit or fires to be kindled for several days. Saint Patrick knew this, for he was well versed in the religious customs of the Irish, and he knew, too, that the penalty for disobeying the priestly order was a terrible death.
None the less, and in spite of being unarmed, he ordered his followers to build an enormous fire that could be seen for miles. When the great logs and the faggots were piled together Saint Patrick kindled the pile with his own hands and the flames shot high in the air, throwing strange shadows on the trees and causing the Irish to cry out in fear and astonishment. The Druid priests were greatly angered and perturbed at what Saint Patrick had done, and they went at once to the King, who was named Laoghaire MacNeill, telling him that the foreign band had desecrated the Druid faith and must be punished with death. Then the King told the priests to go and fetch Saint Patrick and bring him to judgment, but the priests feared the fire that had been kindled, thinking that it had magic powers. So they went as far as they dared and called out to Saint Patrick, summoning him to appear before the judges of the land.
Promptly and with fearless demeanor, Saint Patrick joined the priests and was taken before the King. And when the King demanded of him how he had dared to disobey the laws of the country and profane its religion, Saint Patrick answered that he did so because the light of the Christian faith was infinitely brighter than the light of any fire that he or any one else had power to kindle; and that the fire he had built was merely a sign to call the Irish to the worship of the true God. Then he preached, and his words were so wise and spoken with such weight of eloquence that many that heard him became Christians on the spot, and the work of converting Ireland was soon well under way.
There were many of the Irish that loved Saint Patrick, but he had many bitter enemies. On one occasion a powerful Irishman, who was enraged at the Saint for having taken a stone sacred to the Druids for a Christian altar, vowed that he must die. So he lay in wait in a patch of woods near a road over which he knew Saint Patrick would pass, with a sharp javelin to pierce his heart.
