1.) I did not mean to imply that anything remaining in the Cup should not be consumed; however, any residual that does not come out when one reasonable attempts to consume it does wait until after Mass, per the indult, and then it would be emptired out by swirling some water around the inside and consuming it.
2.) I fail to see that someone taking Communion to the sick, and waiting until the dismissal, would in any way contribute to making anyone the least bit indifferent to the Real Presence. I think that the indifference is due to a long (almost two generations) and abysmal period of catechesis that ranges from poor to borderline criminally negligent.
3.) I also do not see that the indult is responsible for any indifference to the Real Presence. We have been following the indult all along. We also are a parish that has had 24 hour adoration for longer than I can remember; well over 10 years at this point.
4.) That there is widespread problems with people’s knowledge and praxis, I would not question. It is, however, possible to attribute that to any number of issues without any valid proof that they have contributed to the problem; too often the attribution is based on personal feelings and dislikes of the issues rather than any real conection to the lack of knowledge and lack of personal response or reverence.
5.) I also do not know of anything that directs one who has just received Communion to take the pyx and leave Mass before it is actually over; although I may like, for example, what Joe Kelly’s parish does, in ours those taking communion to the sick wait for the final prayers and dismissal. As far as conversations on the way out, that is an issue of training, which doesn’t seem to be a problem in our parish.
