The right answer is that the way we receive communion should not detract from the Real Presence and be a distraction to others but apparently it continues to be so. This is especially true at the EF where if one insists on stirring up trouble and receive in the hands, it stirs up a major provocation. I don’t think this is what communion should be about, do you? The Body and Blood of Christ as well as certain sensibilities should be respected.
If everybody in the Church would do no more than consent to the rubrics laid down by the bishops, to the letter and in the spirit, as they teach the spiritual meaning of the proscribed rituals to be, that would be enough respect to sensibility for me.
Other than that–and I don’t criticize those who learn the rubrics and use those as their boundaries, as only the bishops may demand boundaries–there are also the demands of charity to be followed. On that, I mean that we demand charity of ourselves on behalf of others, not the other way around:
“
Everything is lawful," but not everything is beneficial. “Everything is lawful,” but not everything builds up. No one should seek his own advantage, but that of his neighbor…So whether you eat or drink, or whatever you do, do everything for the glory of God. Avoid giving offense, whether to Jews or Greeks or the church of God, just as I try to please everyone in every way, not seeking my own benefit but that of the many, that they may be saved.” 1 Cor. 10:23-24,31-33
Also:
"…Love is not rude, it does not seek its own interests, it is not quick-tempered, it does not brood over injury.…" 1 Cor. 13:5.
So if you do not have scruples but are aware that a brother or sister has scruples, it is charitable to accomodate their scruples, if you can.
When in a situation where you can do almost nothing without offending someone or provoking them to judge you, though, you can wash your hands of worrying about it. You follow the rubrics, of course, but after that you sometimes have to let the busybodies handle their own anxieties, because there is no way to soothe the scruples of all of them. It just depends on where you find yourself.
If we are to have disagreements, we have to discuss them in charity and defer to one another as we can, or we are not in the will of God. Charity, OTOH, covers a multitude of sins. If we foster divisions among ourselves, we will not be praised for it.
In short, we can demand of ourselves more charity than the rubrics proscribe, and most surely we ought to, but unless we have a pastoral office we can really demand no more of anyone else, not on behalf of our own sensibilities.
