But there were impious acts and impure passions that contaminated and defiled the soul. Since this infection could be destroyed only by expiations prescribed by the gods, the extent of the sin and the character of the necessary penance had to be estimated. It was the priest's prerogative to judge the misdeeds and to impose the penalties. This circumstance gave the clergy a very different character from the one it had at Rome. The priest was no longer simply the guardian of sacred traditions, the intermediary between man or the state and the gods, but also a spiritual guide. He taught his flock the long series of obligations and restrictions for shielding their weakness from the attacks of evil spirits. He knew how to quiet remorse and scruples, and to restore the sinner to spiritual calm. Being versed in sacred knowledge, he had the power of reconciling the gods. Frequent sacred repasts maintained a spirit of fellowship among the mystics of Cybele, Mithra or the Baals,[33] and a daily service unceasingly revived the faith of the Isis worshipers. In consequence, the clergy were entirely absorbed in their holy office and lived only for and by their temples. Unlike the sacerdotal colleges of Rome in which the secular and religious functions were not yet clearly differentiated,[34] they were not an { 42} administrative commission ruling the sacred affairs of the state under the supervision of the senate; they formed what might almost be called a caste of recluses distinguished from ordinary men by their insignia, garb, habits and food, and constituting an independent body with a hierarchy, formulary and even councils of their own.[35] They did not return to every-day duties as private citizens or to the direction of public affairs as magistrates as the ancient pontiffs had done after the solemn festival service.
We can readily understand that these beliefs and institutions were bound to establish the Oriental religions and their priests on a strong basis. Their influence must have been especially powerful at the time of the Cæsars. The laxity of morals at the beginning of our era has been exaggerated but it was real. Many unhealthy symptoms told of a profound moral anarchy weighing on a weakened and irresolute society. The farther we go toward the end of the empire the more its energy seems to fail and the character of men to weaken. The number of strong healthy minds incapable of a lasting aberration and without need of guidance or comfort was growing ever smaller. We note the spread of that feeling of exhaustion and debility which follows the aberrations of passion, and the same weakness that led to crime impelled men to seek absolution in the formal practices of asceticism. They applied to the Oriental priests for spiritual remedies.
