The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 19
How he Overcame the Temptation of the Enemy.
The wonderful Ruler of all things, the more he exalts with signs and with wonders his elect whom he loveth, the more does he, according to the Apostle, suffer them to fall into divers temptations, that they may learn and know how to preserve their strength in God, who is their maker, and trust to nothing in themselves or of themselves. Wherefore Patrick, the beloved and the elect of God, is suffered by the divine will to be grievously tempted of Satan, to increase the confusion of the tempter and the glory of him who was tempted, and lest he should be lifted up by the greatness of his miracles or his fastings. For in the night season the prince of darkness rushed on him, and oppressed him as with the weight of a huge stone, and, falling on him, the tempter took from him all sense and motion, causing to him darkness and heaviness, and for the space of three days ceased not to torment and lash him beyond human power to endure. But the saint in his tribulation cried unto the Lord, thrice in His name invoking Elias, the prince of prophets, unto his aid. And Elias, being sent of the Lord with a great brightness, freed him from the pressure of the enemy that hemmed him round, and, wonderfully illumining him both within and without, refreshed the powers of his limbs and his senses. And the enemy of mankind, being put to confusion, was compelled to own himself vanquished by Patrick, and that ever after he could have no power to prevail against him.
