Why do Orthodox Churches have valid Eucharist? How often do they celebrate this?
btw, major denominational christian groups believe in the wrong type of real pressence - they believe that the substance remains bread and wine but somehow Jesus is within those food.
The Catholic unerstanding holds that even though the appearance (that includes ways we understand bread and wine, including physical and chemical properties) is bread and wine, the substance are transformed into actual flesh and blood of Christ.
The Orthodox Churches have a valid Eucharist because they have valid Apostolic Succession re: valid Priesthood. The Roman Catholic Church agrees to intercommunion with the Orthodox Churches, but the Orthodox reject this.
As for the frequency of the celebration of the Divine Liturgy in Orthodoxy (known as āthe Massā in the West), there are specified non-liturgical days such as, for example, all weekdays during Lent.
Originally, on all weekdays during Lent, the Divine Liturgy of the Presanctified was served i.e. the service of Vespers with Holy Communion that was consecrated the previous Lordās Day. Now, the Divine Liturgy, or Mass of the Presanctified (of St Gregory the Dialogist) is celebrated on Lenten Wednesdays and Fridays only.
As an Eastern Catholic, what Iāve always deeply honoured about the Eastern Divine Liturgy is the tremendous sense of awe in its celebration, the icons, the incense, the slowly intoned prayers and the deep reverence for the āmysterium tremendum.ā
There are long prayers of preparation for Holy Communion and thanksgiving afterwards that laity are to fulfill. When receiving Holy Communion, one kisses the edge of the Chalice to honour the Sacred Wound in Christās Heart from which we are nourished in Holy Communion. Add to this the constant making of the Sign of the Cross with bowing etc. - one truly feels transported to heaven!
This sacral context in which the Liturgy/Eucharist is celebrated avoids the Protestant fear that the Eucharist will somehow be taken for granted and not given the highest possible honour it deserves.
Iāve been to a number of different Ritual Catholic Churches - for me, there is nothing like the celebration of the Byzantine Divine Liturgy.
