Polybius knew all that the Christian had done for his son and for Melissa, for him and his, and his jest in saying that Andreas had helped to make him lighter referred to his latest achievement. Julianus, the new governor of the city, who now occupied the residence of the prefect Titianus, had taken advantage of the oppressed people to extract money, and Andreas, by the payment of a large sum, had succeeded in persuading him to sign a document which exonerated Polybius and his son from all criminality, and protected their person and property against soldiers and town guards alike. This safe-conduct secured a peaceful future to the genial old man, and filled the measure of what he owed to the freedman, even to overflowing. Andreas, on his part, felt that his former owner's kiss and brotherly greeting had sealed his acceptance as a free man. He asked no greater reward than this he had just received; and there was another thing which made his heart leap with gladness. He knew now that the fullness of time had come in the best sense for the daughter of the only woman he had ever loved, and that the Good Shepherd had called her to be one of His flock. He could rejoice over this without a pang, for he had learned that Diodoros, too, had entered on the path which hitherto he had pointed out to him in vain. A calm cheerfulness, which surprised all who knew him, brightened the grave man; for him the essence of Christian love lay in the Resurrection, and he saw with astonishment that a wonderful new vitality was rising out of death. For Alexandria, too, the time was fulfilled. Men and women crowded to the rite of baptism. Mothers brought their daughters, and fathers their sons. These days of horror had multiplied the little Christian congregation to a church of ten thousand members. Caracalla turned hundreds from heathenism by his bloody sacrifices, his love of fighting, his passion for revenge, and the blindness which made him cast away all care for his eternal soul to secure the enjoyment of a brief existence. That the sword which had slain thousands of their sons should have been dedicated to Serapis, and accepted by the god, alienated many of the citizens from the patron divinity of the town. Then the news that Timotheus the high-priest had abdicated his office soon after Caesar's departure, and, with his revered wife Euryale, had been baptized by their friend the learned Clemens, confirmed many in their desire to be admitted into the Christian community.
