Is it possible that the encouragement for frequent Eucharist could be changed? Perhaps during Pius X's time it was good for the Church, but one could argue that it isn't so today. Today everybody receives it even though so many of them really shouldn't (civilly remarried people for example). As a result, I feel as if people don't appreciate it the way they should.
I've read of tourists from Japan who'd go to the Vatican and attend Mass, take the Eucharist and not understand what it is. Once when I was at a weekday Mass, some woman went to receive it and pocketed it. A sister noticed it and took the Host back. Another time, I was in college and Lutheran professor I know attended Mass and received the Eucharist. I spoke about it with him later and he didn't feel like he was in the wrong at all; I could prove it with Canon Law but that wouldn't have made a difference to him. People end up thinking it's being passed out like candy. I'm sure a lot of you have at least one story where you know the Eucharist was profaned. I can think of two more off the top of my head but I don't even want to mention them here, they were so disgusting.
In the history of the Church, have there been waves of encouragement then discouragement of frequent Eucharist? Can the trend of frequent reception be reversed? At one time even nuns needed special permission to take the Eucharist daily. Nowadays everyone takes it for granted.
I imagine it would be exceedingly difficult to enforce a change in the rules. But is it possible that the rules could be changed? Has such a thing happened in the past?
