The desert had an atmosphere of Christianity. Many aged solitaries like Arsenius and Paphnutius took to the road with sacred missions. The hermit’s life was not always continuous cave-dwelling. St. Arsenius, a gracious genius, went to the councils of Emperors; we read of men like Paphnutius returning to “the world” at the obedience of the heavenly vision and saving people whom the Lord needed. Thaïs, the courtesan of Alexandria, was taken from the midst of her gay life and brought to a cell in the desert. The anchorites found for her this beautiful prayer, “Thou who formed’st me have mercy,” and Thaïs was saved, though she died. And she was numbered among the Marys. No hermit setting out upon the road took away money with him or had thought for the morrow. That was a golden rule in their ways; money counted for nothing. Serapion the Sindonite sold himself as a slave in order that he might save those who were slaves of the world; and he put the money he received as the price of himself in a pit and covered it with earth. He was a perfect servant, and by his humility and sweetness touched the heart of his master and mistress, who soon learned to say the Lord’s Prayer with him and were converted to Christianity. One day they said to Serapion: “We are unworthy that you should be our servant and slave, take back, we pray you, your freedom!” Serapion replied that he thanked God for the day when his mission was accomplished, and thanked his master and mistress for his freedom. Then he went to the pit where the purchase money was buried and brought it to his two converted friends. They were much astonished, and implored Serapion to keep the money. But he refused though they wept, and he set off for the desert once more, cared for by the Lord.
