Who were “the friends in Cæsar’s household” of whom Paul wrote? Bishop Lightfoot shows of the forty-three Christianized Jews and Greeks, who met Paul when he reached Rome, and whose names may be found in the letter to the Romans; many were in Roman governmental positions of trust. Their names can be found scattered through the _Acts_ and the apostolic letters to Rome and Asia. There seems almost no reason to doubt that the great Epaphroditus, the Greek lover of learning, to whom Josephus dedicated his volume, was the same benevolent Greek of Philippi who supplied Paul with money for his needs in Rome, and who carried Paul’s letter to the Philippians, and who seems to have been under surveillance with Paul in Rome; for in Rome, even if his eyesight would have permitted Paul to follow his mechanical means of supporting himself by tentmaking, there was not the same demand as in the East for tents for desert travel, or in Greece for maritime sailcloth. Aquila and Priscilla, who came later in the Apollos story, like Paul, were tentmakers. Paul’s knowledge of seafaring was gained as sailcloth maker. Always when religious faith wanes, necromancy, clairvoyance, sorcery thrive. The Old World with its dying faiths both Roman and Grecian, was now overrun with sorcerers of every description, practising wonder-working and miracles by methods variously known as Black Magic and White Magic. The knowledge of the methods underlying these powers was undoubtedly drawn from India and Persia. Some workers were good and some were bad. Some miracles were fraudulent and some were undoubtedly genuine—using the word “miracle” in the sense of wonder-working; only the Christians, the Essenes, the Gnostics, the Nazarenes refused to work these wonders for profit. For some reason or other, probably because they had lost faith in God, and learned magic from the Persians and the Babylonians, the Jews had become great sorcerers in Paul’s day. More will be given of this in the chapter on Apollos. It is given also in the Acts. The reference of Onesimus to the luminous look, or radiance round Paul in the half dark, and the old Idumean’s legend of Antioch’s invading soldiers finding nothing in the Holy of Holies of the Temple between the Cherubim and Seraphim but a little thin blue flame, would have been laughed out of any court of evidence by science ten years ago. Not so to-day. The study of wireless waves is opening the door to the wonder-world of these waves.
