Through union with Christ, as celebrated in the sacrament of Holy Communion, the Church on earth participates with the Church in heaven in the eternal worship of God.
“Communion” means being “one with” someone in union and unity. For Christians, it refers to the unity of the three Persons within the one Being of God, to our union with God through our union with Christ, and to our unity with one another in Christ.
Schmemann's main point, in my reading of the book, is this: The Eucharist is the entire service, the whole of the Liturgy.
The image of the cross immediately brings to mind that sacrifice. That symbol has been imbued with a power beyond mere words. Likewise the bread and wine of communion have been imbued with power. Jesus said we must eat his flesh and drink his blood.
A modern American low church, nondenominational experience seems like a bland saltine cracker compared to the majestic cake of ancient rites and liturgy.
