The Holy Eucharist, which is known as the Divine Liturgy, is the central and most important worship experience of the Orthodox Church. Often referred to as the "Sacrament of Sacraments", it is the Church's celebration of the Death and Resurrection of Christ offered every Sunday and Holy day. All the other Sacraments of the Church lead toward and flow from the Eucharist, which is at the center of the life of the Church.
