This, brought to my attention, from Cyril of Jerusalem’s Catechetical Lectures, toward the very end:
Approaching therefore, come not with thy wrists extended, or they fingers open; but make they left hand as if a throne for thy right, which is on the eve of receiving the King. And having hallowed thy palm, receive the Body of Christ, saying after it, Amen. Then after thou hast with carefulness hallowed thy eyes by the touch of the Holy Body, partake thereof; giving heed lest thou lose any of it; for what thou losest, is a loss to thee as it were from one of thine own members. For tell me, if any one gave thee gold dust, wouldest thou not with all precaution keep it fast, being on thy guard against losing any of it, and suffering loss? How much more cautiously then will thou observe that not a crumb falls from thee, of what is more precious than gold and precious stones?
Then after having partaken of the Body of Christ, approach also to 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. And while the moisture is still upon thy lips, touching it with thy hands, hallow both thine eyes and brow and the other senses. Then wait for the prayer, and give thanks unto God, who has accounted thee worthy of so great mysteries. (Mystagogical Cathacheses, V, 21-22)
One of the hills the Trad Catholics die on is reception of the Host on the tongue. But as is the case with many things, the Eastern churches, whose sacramental validity has never been challenged, do many things in liturgical practice that haven’t sat well with their Western counterparts. This is one of them. Many of the “novelties” that are decried by Anglican and Catholic Trad alike are in reality imports from these churches, and as such are a real nuisance to these trads.
I did a series a few years back on Cyril of Jerusalem’s Catechetical Lectures. For me, it was an interesting and informative journey, and I commend it again to my visitors.
