I believe that, after the consecration, there is no more bread and wine. The gifts are changed into the Body and Blood of our Lord Jesus Christ by the Holy Spirit.
My EO uncle says: "The Roman Catholic Church believes when the bread and wine are consecrated their substance no longer remains, but is wholly transformed into the body and blood of Christ. This is opposed to the Orthodox view that after the consecration the bread and wine remain with the body and blood of Christ."
I've always taken Protopresbyter Michael Pomazansky as a good source of teaching and he says the contrary in his book Orthodox Dogmatic Theology:
"In the Mystery of the Eucharist, at the time when the priest, invoking the Holy Spirit upon the offered Gifts, blesses them with the prayer to God the Father: “Make this bread the precious Body of Thy Christ; and that which is in this cup, the precious Blood of Thy Christ; changing them by Thy Holy Spirit” — the bread and wine actually are changed into the Body and Blood by the coming down of the Holy Spirit. After this moment, although our eyes see bread and wine on the Holy Table, in their very essence, invisibly for sensual eyes, this is the true Body and true Blood of the Lord Jesus, only under the “forms” of bread and wine."
Here are some Fathers that support Protopresbyter Michael Pomazansky:
http://www.scripturecatholic.com/the_eucharist.html#tradition-IIThe EO Synod of Jerusalem (1672), Decree 17 says:
Further [we believe] that after the consecration of the bread and of the wine, there no longer remaineth the substance of the bread and of the wine, but the Body Itself and the Blood of the Lord, under the species and form of bread and wine; that is to say, under the accidents of the bread.
[...]
Further, we believe that by the word “transubstantiation” the manner is not explained, by which the bread and wine are changed into the Body and Blood of the Lord, — for that is altogether incomprehensible and impossible, except by God Himself, and those who imagine to do so are involved in ignorance and impiety, — but that the bread and the wine are after the consecration, not typically, nor figuratively, nor by superabundant grace, nor by the communication or the presence of the Divinity alone of the Only-begotten, transmuted into the Body and Blood of the Lord; neither is any accident of the bread, or of the wine, by any conversion or alteration, changed into any accident of the Body and Blood of Christ, but truly, and really, and substantially, doth the bread become the true Body Itself of the Lord, and the wine the Blood Itself of the Lord, as is said above.
I'm not planning on changing my opinion, but, I was wondering how prevalent my uncle's view is amongst the Eastern Orthodox.
