Yet about the modest supper-room of the Christians alone a great ado is made. Our feast explains itself by its name. The Greeks call it agapè, i.e., affection. Whatever it costs, our outlay in the name of piety is gain, since with the good things of the feast we benefit the needy; not as it is with you, do parasites aspire to the glory of satisfying their licentious propensities, selling themselves for a belly-feast to all disgraceful treatment,—but as it is with God himself, a peculiar respect is shown to the lowly. If the object of our feast be good, in the light of that consider its further regulations. As it is an act of religious service, it permits no vileness or immodesty. The participants, before reclining, taste first of prayer to God. As much is eaten as satisfies the cravings of hunger; as much is drunk as befits the chaste. They say it is enough, as those who remember that even during the night they have to worship God; they talk as those who know that the Lord is one of their auditors. After manual ablution, and the bringing in of lights, each is asked to stand forth and sing, as he can, a hymn to God, either one from the holy Scriptures or one of his own composing,—a proof of the measure of our drinking. As the feast commenced with prayer, so with prayer it is closed. We go from it, not like troops of mischief-doers, nor bands of vagabonds, nor to break out into licentious acts, but to have as much care of our modesty and chastity as if we had been at a school of virtue rather than a banquet.
