Acts 16:21

Being Romans. The Romans granted absolute toleration to conquered nations to follow their own religious customs, and took the gods of these countries under their protection. Otho, Domitian, Commodus, and Caracalla were zealous partisans of the worship of Isis; Serapis and Cybele were patronized at Rome; and in the reign of Nero the religious dilettante at Rome affected Judaism, and professed to honor the name of Moses and the sacred books. Poppaea, Nero's consort, was their patroness, and Seneca said, "the Jewish faith is now received on every hand. The conquered have given laws to the conquerors." On the other hand, there were laws which forbade the introduction of strange deities among the Romans themselves. In 186 B. C., when stringent measures were taken by the government for the repression of Bacchanalian orgies in Rome, one of the consuls, addressing an assembly of the people, said : "How often in the ages of our fathers was it given in charge to the magistrates to prohibit the performance of any foreign religious rites; to banish strolling sacrificers and soothsayers from the forum, the circus, and the city; to search for and burn books of divination; and to abolish every mode of sacrificing that was not conformable to the Roman practice" (Livy, 39, 16) It was contrary to strict Roman law for the Jews to propagate their opinions among the Romans, though they might make proselytes of other nations.
