However, in this regard, as in their conception of the divinity, the Egyptian mysteries followed the general progress of ideas more than they directed it.
Philosophy transformed them, but found in them little inspiration.
How could a religion, of which neither the theology nor the ethics was really new, stir up at the same time so much hostility and fervor among the Romans? To many minds of to-day theology and ethics constitute religion, but during the classical period it was different, and the priests of Isis and Serapis conquered souls mainly by other means. They seduced them by the powerful attraction of the ritual and retained them by the marvelous promises of their doctrine of immortality.
To the Egyptians ritual had a value far superior to that we ascribe to it to-day. It had an operative strength of its own that was independent of the intentions of the officiating priest. The efficacy of prayer depended not on the inner disposition of the believer, but on the correctness of the words, gestures and intonation. Religion was not clearly differentiated from magic. If a divinity was invoked according to the correct forms, especially if one knew how to pronounce its real name, it was compelled to act in conformity to the will of its priest. The sacred words were an incantation that compelled the superior powers to obey the officiating person, no matter what purpose he had in view. With the knowledge of the liturgy men acquired an immense power over the world of spirits. Porphyry was surprised and indignant because the Egyptians sometimes dared to threaten the gods in their orations.[[54]] In the consecrations the priest's summons compelled the gods to come and animate their
statues, and thus his voice created divinities,[[55]] as originally the almighty voice of Thoth had created the world.[[56]]
The ritual that conferred such superhuman power[[57]] developed in Egypt into a state of perfection, completeness and splendor unknown in the Occident. It possessed a unity, a precision and a permanency that stood in striking contrast to the variety of the myths, the uncertainty of the dogmas and the arbitrariness of the interpretations. The sacred books of the Greco-Roman period are a faithful reproduction of the texts that were engraved upon the walls of the pyramids at the dawn of history, notwithstanding the centuries that had passed. Even under the Cæsars the ancient ceremonies dating back to the first ages of Egypt, were scrupulously performed because the smallest word and the least gesture had their importance.
This ritual and the attitude toward it found their way for the most part into the Latin temples of Isis and Serapis. This fact has long been ignored, but there can be no doubt about it. A first proof is that the clergy of those temples were organized just like those of Egypt during the period of the Ptolemies.[[58]] There was a hierarchy presided over by a high priest, which consisted of prophetes skilled in the sacred science, stolistes, or ornatrices,[[59]] whose office it was to dress the statues of the gods, pastophori who carried the sacred temple plates in the processions, and so on, just as in Egypt. As in their native country, the priests were distinguished from common mortals by a tonsure, by a linen tunic, and by their habits as well as by their garb. They devoted themselves entirely to their ministry and had no other profession. This
sacerdotal body always remained Egyptian in character, if not in nationality, because the liturgy it had to perform remained so. In a similar manner the priests of the Baals were Syrians,[[60]] because they were the only ones that knew how to honor the gods of Syria.
In the first place a daily service had to be held just as in the Nile valley. The Egyptian gods enjoyed a precarious immortality, for they were liable to destruction and dependent on necessities. According to a very primitive conception that always remained alive, they had to be fed, clothed and refreshed every day or else perish. From this fact arose the necessity of a liturgy that was practically the same in every district. It was practised for thousands of years and opposed its unaltering form to the multiplicity of legends and local beliefs.[[61]]
