The worship of God, which has been at the heart of the Community’s life since its founding, has developed over the years into a full daily cycle of prayer in word and sacrament. The Eucharist is the Community’s principal act of worship. Presided over by one of the resident ordained clergy, the Eucharistic liturgy incorporates forms and prayers shared by most branches of the church, drawing from both early Christian sources and contemporary expressions. The Liturgy of the Hours (Divine Office) is the most frequent form of daily prayer. The Community gathers at designated hours—morning, noon, evening, and night—to worship with psalms, hymns, readings, and prayers using the ancient practice of Gregorian chant.
