Trust not the decision of thy palate; no, but to faith unfaltering; for when we taste we are bidden to taste not bread and wine, but the sign of the Body and Blood of Christ.
Approaching, therefore, come not with thy wrists extended or thy fingers open; but make Thy left hand as if a throne for thy right, wich is on the eve of receiving the King. And having allowed thy palm, receive the Body of Christ, saying after it, Amen....
Then after having partaken of the Body of Christ, approach also the Cup of His Blood; not stretching forth thine hands, but bending and saying in the way of worship and reverence, Amen, be thou hallowed by partaking also of the Blood of Christ.
--St. Cyril of Jerusalem, Mystagogical Catechesis V:20-22 (picture is from our sister parish, Trinity in Worden, IL)
