"What about St. Cyril? Of course, the promoters of “communion in the hand” generally make little mention of the evidence we have brought forward. They do, however, make constant use of the text attributed to St. Cyril of Jerusalem, who lived in the fourth century at the same time as St. Basil. Dr. Henri LeClerq summarized things as follows: “Saint Cyril of Jerusalem recommended to the faithful that on presenting themselves to receive Communion, they should have the right hand extended, with their fingers together, supported by the left hand, and with the palm a little bit concave; and at the moment in which the Body of Christ was deposited in the hand, the communicant would say: Amen.” There is more to this text than just the above, however. It also on to proposes the following:
“Sanctify your eyes with contact with the Holy Body… “When your lips are still wet, touch your hand to your lips, and then pass you hand over your eyes, your forehead and your other senses, to sanctify them.” This rather odd (or even superstitious? Irreverent?)recommendation has caused scholars to question the authenticity of this text. Some think that perhaps there has been an interpolation, or that it is really the saint’s successor who wrote it. It is not impossible that the text is really the work of the Patriarch John, who succeeded Cyril in Jerusalem. But this John was of suspect orthodoxy. This we know from the correspondence of St. Epiphanius, St. Jerome, and St. Augustine. So, in favour of communion in the hand we have a text of dubious origin and questionable content. And on the other hand, we have reliable witnesses, including two great popes, that placing the Sacred Host in the mouth of the communicant was already common and unremarkable in at last the fifth= century. Clericalism? Is it not a form of clericalism to allow the priest to touch the Sacred Host and to disallow the laity to do the same? But priests were not allowed to touch the Blessed Sacrament except out of necessity. In fact, other than the celebrant of the Mass itself, no one else receiving Communion, not even a priest, could do so in the hand. And so, in the traditional liturgical practice of the Roman Rite, if a priest were assisting at Mass (and not celebrating) and if he wished to receive Holy Communion, he did not do so by his own hand: he received on the tongue form another priest. The same would be true of a Bishop. The same is true of the Pope himself. When Pope St. Pius X, for example, was on his death bed in August of 1914, and Holy Communion was brought to him as Viaticum, he did not and was not allowed to receive in the hand: he received on the tongue according to the law and practice of the Catholic Church. This confirms a basic point: out of reverence, there should be no unnecessary touching of the Sacred Host. Obviously someone is needed to distribute the Bread of Life. But it is not necessary to make each man, woman and child into his own “eucharistic minister” and multiply the handling and fumbling and danger of dropping and loss of Fragments. Even those whose hands have been specially consecrated to touch the Most Holy Eucharist, namely the priests, should not do so needlessly."
