Less valuable in itself, but not less persistent, as we can still see in our own Christian church, was the notion that only the initiates, who by purificatory rites had been received into the sacred association, could hope for salvation. Union with the divine nature and future blessedness were thus made to depend on sacraments rather than on virtue. Indeed, we need not suppose that here any more than in the mysteries at Eleusis there was originally any requirement of a virtuous life. But reason and an awakened ethical sense among the Greeks began early to demand of the initiates compliance with the recognized standards of morality, as the passages already quoted show; and there can be no doubt that in due time most of the various mysteries contributed to the ethical life. Yet the inevitable tendency in the opposite direction made itself felt and there were many Orphic charlatans and quacks who promised salvation to all who would undergo the cheap rites of their initiations. * * * * * We must now glance at a contemporaneous and related movement—I mean Pythagoreanism, which will have sprung into the thoughts of many of you already. Whether Orphism learned from Pythagoras or Pythagoras from Orphism cannot be determined; but it seems probable that Croton was already an Orphic center when about 530 B.C. Pythagoras of Samos after long travels established there an association which combined in a way hitherto unknown religious and philosophic aims. Pythagoras may have attached himself to some group of Orphics already in existence and have inspired it with his political and philosophic interests. In any case his society, which was opposed to the democratic temper of Croton, became in time important enough to be regarded with suspicion and forced to move to Metapontum; ultimately the members were dispersed carrying their doctrines with them throughout the Greek world.
