We
[Orthodox] have inherited the customary exposition of the sacramental liturgy
from the holy Apostles and their successors, the Doctors of the Church. We
shall discover, with respect to none of the aforesaid loci, that the
gift of the Eucharist is hallowed and fructified/perfected (τελειουσθαι) by purely dominical phrases and those words
alone. Furthermore, [we shall discover] also that [the gift] is altered (μεταποιεισθαι) into the Lord’s body and blood. . . . And we beseech you to
look graciously upon these gifts set before you, O God who needs nothing, to
accept them both in honor of your Christ and to send down (καταπεμψοις) your Holy Spirit
upon this sacrifice (θυσια), the witness of the sufferings of the Lord Jesus,
that he may reveal (αποφηνοι) this bread as body of your Christ, and this cup as
blood of your Christ. . . . Have mercy on us, O God, according to your great
mercy and send out (εξαποστειλον) upon us and upon these holy
gifts set before you your all-Holy Spirit . . . that he may dwell in them, and by his holy and good and
glorious coming, may sanctify (αγιαση)
them, and make (ποιηση) this bread the holy body of your Christ . .
. and this cup the precious blood of your Christ. (The Libellus of Mark
