In various other ways the traditional practice was modified. Originally a "supper," it was frequently partaken of after the Agapæ or love feasts; but in the fourth century the irrepressible disorders of those assemblages led to their being officially discountenanced, and they gradually died out. Soon the Mass in the churches became a regular morning rite, and the eucharist was taken fasting. After Leo the Great, in the Roman services, it was even administered several times in the day. Finally, in or before the eleventh century, the priesthood, from motives either of economy or sobriety, began to withhold the winecup from communicants, and to reserve it for the priests--a practice which Leo the Great had denounced as heretical. The official argument seems to have been that "the body must include the blood," and that the miracle which turned the bread into flesh created the divine blood therein. One of the most popular miracle stories was to the effect that when once a Jew stabbed a Host, it bled; and the Host in question was long on exhibition. Of older date, apparently, is the administration of the bread in the form of a wafer, this being admittedly an imitation either of the ancient pagan usage of consecrating and eating small round cakes in the worship of many deities, or of the Jewish unleavened bread of the Passover. It may, indeed, have come through Manichæism, which at this point followed Mazdean usage; and as the Manichæans also had the usage of bread without wine, it may be that both practices came from them in the medieval period. But as the priestly practice of turning round at the altar was taken direct from ancient paganism, with the practice of shaving the head, it is likely that the wafer was also.
