accomplished the objects of his journey, he again returned to Alexandria.”[10] It was in the year 216 that the Emperor Caracalla visited Alexandria, and directed a bloody persecution against its inhabitants, especially the literary members of the community, in revenge for the sarcastic verses which had been composed against him for the murder of his brother Geta, a crime which he had perpetrated under circumstances of the basest treachery and cruelty. Origen occupied too prominent a position in the literary society of the city to be able to remain with safety, and therefore withdrew to Palestine to his friend Bishop Alexander of Jerusalem, and afterwards to Cæsarea, where he received an honourable welcome from Bishop Theoctistus. This step proved the beginning of his after troubles. These two men, filled with becoming admiration for the most learned teacher in the Church, requested him to expound the Scriptures in their presence in a public assembly of the Christians. Origen, although still a layman, and without any sacerdotal dignity in the Church, complied with the request. When this proceeding reached the ears of Demetrius, he was filled with the utmost indignation. “Such an act was never either heard or done before, that laymen should deliver discourses in the presence of the bishops,”[11] was his indignant remonstrance to the two offending bishops, and Origen received a command to return immediately to Alexandria. He obeyed, and for some years appears to have devoted himself solely to his studies in his usual spirit of self-abnegation.
