The sacrament of the Lord's supper. The word properly signifies giving thanks. As to the manner of celebrating the eucharist among the ancient Christians, after the customary oblations were made, the deacon brought water to the bishops and presbyters standing round the table to wash their hands; according to that passage of the Psalmist, "I will wash my hands in innocency, and so will I compass thy altar, O Lord." Then the deacon cried out aloud, "Mutually embrace and kiss each other, " which being done, the whole congregation prayed for the universal peace and welfare of the church, for the tranquility and repose of the world, for the prosperity of the age, for wholesome weather, and for all ranks and degrees of men. After this followed mutual salutations of the minister and people; and then the bishop or presbyter, having sanctified the elements by a solemn benediction, broke the bread, and delivered it to the deacon, who distributed it to the communicants, and after that the cup. The sacramental wine was usually diluted or mixed with water. During the time of administration they sang hymns and psalms; and having concluded with prayer and thanksgiving, the people saluted each other with a kiss of peace, and so the assembly broke up.
