Divine Liturgy is the standard form of eucharistic service as celebrated in the Eastern Orthodox Church and Eastern Catholics. The rite consists of three main parts: proskomede (not attended by the faithful, when the priests prepares bread and wine for the service), liturgy of the faithful (where Scripture is read) and liturgy of the faithful (which includes the consecration of bread and wine and communion). The service is highly elaborate. It is served on Sundays, feast days and even daily (in monasteries). The two main Divine Liturgies are those of St. John Chrysostom and St. Basil the Great (which differ only slightly, and only in eucharistic canon).
