We know what opposition had been made in Rome even to the philosophy of Greece; much greater would be the aversion of constitutional statesmen and lawyers to the ritual of barbarians. Religion was the Roman point of honor. "Spaniards might rival them in numbers," says Cicero, "Gauls in bodily strength, Carthaginians in address, Greeks in the arts, Italians and Latins in native talent, but the Romans surpassed all nations in piety and devotion." It was one of their laws, "Let no one have gods by himself, nor worship in private new gods nor adventitious, unless added on public authority." Mæcenas in _Dio_ advises Augustus to honor the gods according to the national custom, because the contempt of the country's deities leads to civil insubordination, reception of foreign laws, conspiracies, and secret meetings. "Suffer no one," he adds, "to deny the gods or to practise sorcery." The civilian Julius Paulus lays it down as one of the leading principles of Roman law, that those who introduce new or untried religions should be degraded, and if in the lower orders put to death. In like manner, it is enacted in one of Constantine's laws that the haruspices should not exercise their art in private; and there is a law of Valentinian's against nocturnal sacrifices or magic. It is more immediately to our purpose that Trajan had been so earnest in his resistance to _hetæriæ_ or secret societies, that, when a fire had laid waste Nicomedia, and Pliny proposed to him to incorporate a body of a hundred and fifty firemen in consequence, he was afraid of the precedent and forbade it. What has been said will suggest another point of view in which the oriental rites were obnoxious to the government--namely, as being vagrant and proselytizing religions. If it tolerated foreign superstitions, this would be on the ground that districts or countries within its jurisdiction held them; to proselytize to a rite hitherto unknown, to form a new party, and to propagate it through the empire--a religion not local, but catholic--was an offence against both order and reason. The State desired peace everywhere, and no change; "considering," according to Lactantius, "that they were rightly and deservedly punished who execrated the public religion handed down to them by their ancestors."
