The little red Orthodox prayer book by the Antiochian Archdiocese says this:
"(Then the Priest takes up the holy Bread in both hands and elevates it above the Diskarion, saying aloud:) ... (As the Priest lowers the holy Bread, he makes with it the sign of the Cross thrice, above the Diskarion. Meanwhile the Choir sings the following Hymn; the people sit.)
In the little red prayer book, it refers to it as the "Elevation"
The Divine Liturgy Hymnal (Compl. by Fr. Igor Soroka), 1979 also refers to it as the "Elevation".
In "Let us Attend: A Journey through the Orthodox Divine Liturgy" by Fr. Lawrence Farley, it says:
"The deacon calls all to holy anticipation saying, 'Let us attend!' and the Priest elevates the Body of Christ, summoning the faithful to draw near, saying, 'The holy things are for the holy!' The faithful cry out in joy, 'One is holy! One is the Lord - Jesus Christ, to the glory of God the Father!'"
He then speaks more about the phrase "Holy things are for the Holy", but he doesn't refer anymore about the elevation of the body of Christ.
In "The Orthodox Faith, Volume II: Worship" by Fr. Thomas Hopko, it says:
"The consecrated Lamb is then elevated with the proclamation: 'Holy things are for the Holy!' The people respond: 'One is Holy! One is the Lord, Jesus Christ! To the Glory of God the Father, Amen.' The celebrant then breaks the Lamb into four pieces according to the way it was cut at the prothesis."
