Episcopalians traditionally gather in community to worship together on Sundays. The principal worship service is the celebration of Holy Eucharist, also known as the Lord’s Supper, Holy Communion, or Mass. Other regular and formal rites for public worship include the Daily Office (the fourfold pattern of daily prayer including Morning Prayer, Noonday Prayer, Evening Prayer, and Compline) and the Sacraments (a variety of rites that mark the spiritual journey).
