"Approaching, do not come with your palms stretched flat nor with fingers separated. But making your left hand a seat for your right, and hollowing your palm, receive the Body of Christ, responding Amen. And having with care hallowed your eyes by the touch of the Holy Body, take it, vigilant lest you drop any of it."
~ Cyril, Bishop of Jerusalem, Doctor of the Church, Saint; on the proper technique for receiving Holy Communion in the hand (circa A.D. 347).
