In the bad old pre-Vatican II days, post- Vatican II progressives often made disparaging remarks about the religious education of the unwashed laity of that time. Most Catholics did not go to Catholic schools or CCD programs. Their only exposure to the truths about God, the Mass and other sacraments was by attending Mass. Prior to Vatican II most Catholics would never question publicly or answer publicly that they did not believe in the Real Presence.
Why? Because the Law of Prayer is the Law of belief. The manner in which the Mass was celebrated, for the most part, vast, vast most part, was reverently. And most Catholics with minimal religious education knew and believed in the Real Presence of Christ.
Today's enlightened lay Catholics not so much.
Is it too much to ask for a return to kneeling for Holy Communion? I contend that this is even more important than ad orientem. And I know from first hand experience what John Nolan says about kneeling for Holy Communion in the Ordinary Form. That people who receive in the hand while kneeling would place the Host in their mouth in a more reverent way while kneeling than they would while standing and moving. They would not get up until the Host was in their mouth.
And yes, Extraordinary Ministers of Holy Communion should be used sparingly and when truly needed. We need fewer, who should be properly trained and educated for this ministry and required to wear an alb (as a sign of their baptismal garment/dignity). Holy Communion by Intinction could be quickly accomplished and without rushing at the altar railing with one priest and one extraordinary minister of Holy Commuion. Thus the EMHC could act as the adult server of the Mass as well.
