Beside the point: Fact is that taking by hand is less referential. Jung who grew up Calvinist once described Holy Communion by the Swiss Calvinist rite as spiritually “dry.” It ceases being a personal reception of the Lord and became a mere ceremony. It certainly was treated that way in the Cumberland Presbyterian church I attended when I was young.
Not necessarily. I'm an Extraordinary Minister of the Eucharist, and I've given the Body of Christ to communicants in both ways. There are some who receive in the hand who seem oblivious to the great Gift they have, but most receive in a very reverent manner.
