The reason the Church excommunicated people for things like Communion in the hand was because the Church was defending its most precious possession, the Body of Christ. It's a pity that more people don't see that the reason so many Catholics don't believe the traditional teaching about the Eucharist is because of the complete lack of reverence for the Sacred Species. The traditional disciplines have been proven to be correct by the complete shambles the typical parish liturgy has become.
St. Pius X would run out of a typical Church in horror if he saw what was being practiced today. But I'm sure you would just consider him a naive old fool. He can't compare to Annibale Bugnini, Rembert Weakland and the other "liturgists" who have given the Church her "new springtime".
That must be why Christ Himself, at the Last Supper, said "Take and eat," not "stick out your tongue..."
You think it is sacreligious for a mere layman to touch the Body of Christ. I don't, and the Church doesn't either.
