Fr. John Hardon, S.J., " Communion In The Hand—I Wish To Repeat And Make As Plain As I Can—Is A Weakening, A Conscious, Deliberate Weakening Of Faith In The Real Presence"

"We were at concelebrated Mass with the Holy Father, and we were absolutely forbidden to give Communion in the hands. Communion in the hand, Communion in the hand began, in the hand, with the publication of the Dutch Catechism with nobody's permission except the bishops—in effect, in principle separated themselves from the Holy See. One country after another began then to ask for permission, which the Dutch bishops never asked for, permission to receive Communion in the hand. I was asked by the [U.S.] bishops' conference to write a defense of Communion on the tongue, and I can again talk for hours.

"In the very, very early Church, Communion was given in the hands. However, as the faith of the Christians weakened in the Real Presence, by the 5th, 6th centuries Communion on the tongue became mandatory—remained mandatory until the present century. Behind Communion in the hand—I wish to repeat and make as plain as I can—is a weakening, a conscious, deliberate weakening of faith in the Real Presence.

And the American hierarchy took most—three times, those wanting Communion in the hand kept pushing and pushing. Finally, meantime, I was asked by the vice-president of the Catholic Conference of Bishops to defend Communion on the tongue, which I did. To get enough votes to give Communion in the hand, bishops who were retired, bishops who were dying, were solicited to vote to make sure that the vote would be affirmative in favor of Communion in the hand. Whatever you can do to stop Communion in the hand will be blessed by God.”
