It is deemed entirely appropriate, in this place, to discuss a peculiar phase of the law of treason in its relationship to the trial of Jesus. It is easily demonstrable that the teachings of Christ were treasonable under Roman public law. An essential and dominating principle of that law was that the imperial State had the right to regulate and control the private consciences of men in religious matters. It was held to be an attribute of the sovereignty of Rome that she had the right to create or destroy religions. And the theory of the Roman constitution was that the exercise of this right was not a religious but a governmental function. The modern doctrine of the separation of Church and State had no place in Roman politics at the time of Christ. Tiberius Cæsar, at the beginning of his reign, definitely adopted the principle of a state religion, and as Pontifex Maximus, was bound to protect the ancient Roman worship as a matter of official duty. Roman treatment of foreign religions, from first to last, is a most interesting and fascinating study. Polytheistic above all other nations, the general policy of the Roman empire was one of toleration. Indeed she not only tolerated but adopted and absorbed foreign worships into her own. The Roman religion was a composite of nearly all the religions of the earth. It was thus natural that the imperial State should be indulgent in religious matters, since warfare upon foreign faiths would have been an assault upon integral parts of her own sacred system. It is historically true that attempts were made from time to time by patriotic Romans to preserve the old Latin faith in its original purity from foreign invasion. The introduction of Greek gods was at first vigorously opposed, but the exquisite beauty of Greek sculpture, the irresistible influence of Greek literature, and the overwhelming fascination of Greek myths, finally destroyed this opposition, and placed Apollo and Æsculapius in the Roman pantheon beside Jupiter and Minerva. At another time the senate declared war on the Egyptian worship which was gradually making its way into Rome. It had the images of Isis and Serapis thrown down; but the people set them up again. It decreed that the temples to these deities should be destroyed, but not a single workman would lay hands upon them. Æmilius Paulus, the consul, was himself forced to seize an ax and break in the doors of the temple. In spite of this, the worship of Isis and Serapis was soon again practiced unrestrained at Rome.[46] It is further true that Rome showed not only intolerance but mortal antagonism to Druidism, which was completely annihilated during the reign of the Emperor Claudius. A decree of the Roman senate, during the reign of Tiberius, ordered four thousand freemen charged with Egyptian and Jewish superstitions out to Sardinia to fight against and be destroyed by the banditti there, unless they saw fit to renounce these superstitions within a given time.[47]
