§ 36. The Religious Policy of the Emperors from Heliogabalus to Philip the Arabian, 217-249
With the brief exception of the reign of Maximinus Thrax (235-238), Christians enjoyed peace from the death of Caracalla to the death of Philip the Arabian. This was not due [pg 152] to disregard of the laws against Christians nor to indifference to suspected dangers to the Empire arising from the new religion, but to the policy of religious syncretism which had come in with the family of Severus. The wife of Septimius Severus was the daughter of Julius Bassianus, priest of the Sun-god of Emesa, and of the rulers of the dynasty of Severus one, Heliogabalus, was himself a priest of the same syncretistic cult, and another, Alexander, was under the influence of the women of the same priestly family.

Lampridius is one of the Scriptores Historiæ Augustæ, by whom is a series of lives of the Roman emperors. The series dates from the fourth century, and is of importance as containing much information which is not otherwise accessible. The dates of the various lives are difficult to determine. Avitus Bassianus, known as Heliogabalus, a name he assumed, reigned 218-222.
Ch. 3. But when he had once entered the city, he enrolled Heliogabalus among the gods and built a temple to him on the Palatine Hill next the imperial palace, desiring to transfer to that temple the image of Cybele, the fire of Vesta, the Palladium, the sacred shields, and all things venerated by the Romans; and he did this so that no other god than Heliogabalus should be worshipped at Rome. He said, besides, that the religions of the Jews and the Samaritans and the Christian worship should be brought thither, that the priesthood of Heliogabalus should possess the secrets of all religions.
Ch. 6. Not only did he wish to extinguish the Roman religions, but he was eager for one thing throughout the entire world—that Heliogabalus should everywhere be worshipped as god.
Ch. 7. He asserted, in fact, that all the gods were servants of his god, since some he called his chamber-servants, others slaves, and others servants in various capacities.

Alexander Severus (222-235) succeeded his cousin Heliogabalus. The mother of Alexander, Julia Mammæa, sister of Julia Soæmias, mother of Heliogabalus, was a granddaughter of Julius Bassianus, whose daughter, Julia Domna, had married Septimius Severus. It was through marriages with the female descendants of Julius, who was priest of the Sun-god at Emesa, that the members of the dynasty of Severus were connected and their attitude toward religion determined. It was in the reign of Alexander that syncretism favorable to Christianity was at its height.
