Holy Liturgy Sacred Liturgy is the very heart of Eritrean Orthodox worship. All the various kinds and types of Orthodox prayer and ritual cluster around the Sacrifice of the Mass that was instituted by the Lord the same night in which He was betrayed (1Cor. 11:23-25). The Church of Eritrea has fourteen Anaphoras, a unique phenomenon in any Christian Church. Each is used on special occasions to mark the observance of a particular Holy day. Though the Anaphoras differ in length and content, they have common characteristics. They stress the Incarnation, the Last Supper, the Crucifixion and the Resurrection. In principle the Mass is conducted in Ge'ez, the ancient classical and liturgical language of Eritrea. Today however, the readings and certain portions of the liturgy are in the vernacular, Tigrigna. The congregation, both men and women, may join in the singing. When presiding over liturgy, in addition to the celebrant (main priest) and at least one other priest, the presence of three deacons is required.
