Nothing in the document states that an EMHC may bless in lieu of distributing Holy Communion. Redemptionis Sacramentum doesn’t include that provision, either.
Well, yes, but it also doesn’t specifically say that a priest is allowed to do it, either. Are there are circumstances where a Christian, asked to give a blessing, should refrain from giving a blessing proper to their state in life? It’s become such a widespread practice that deciding how to handle it and, if the decision is to end it then
how to end it, has become a pastoral problem.
There is a lot of sympathy in place for this practice of blessing non-communicants during Holy Communion, no matter who gives the blessing. The option of giving a blessing gives an “out” concerning what to do when confronted with a child too young to receive or a person who realizes that they may not receive while in line. They aren’t just “sent away empty.” Non-Catholics attending Mass have less grounds to feel excluded.
OTOH, rubrics are rubrics, and there are those who argue that there ought not be so much as a single stray gesture not specified in the rubrics. Even if one could prove that this isn’t strictly correct, dealing with the scandal that can be taken when things are added is a pastoral issue, too. It doesn’t work to just accomodate the sensibilities of those who are the most “touchy-feely.”
It seems to me that either blessings given during the distribution of Holy Communion should be done away with, because it is not in the rubrics for either priest or EMsHC to do anything other than distribute Holy Communion during that time, or, if it is deemed “part” of the process of distributing Holy Communion, that the EMHC ought to be extraordinary ministers of blessings, too. I mean, if it is permissible to include the laity in distributing what is actually a sacrament, surely this can be somehow accomodated. Like the requirement that the EMsHC are NOT allowed to self-communicate, though, it seems prudent to restrict blessings by EMsHC to those blessings proper for the laity. EMsHC ought not to be any more “extraordinary” than absolutely necessary…IMHO.
This is a question that is worth direct treatment by the local bishops, though, unless the Vatican deems it worth direct treatment by the Holy Father or his officers for liturgy. It’s really their call, whatever we think. I do hope that call is made more explicitly, one way or the other, before long.
If it is left up to the local bishops, though, I think ours will either explicitly allow the practice or else leave the matter to the discretion of the celebrants or the pastors. This is a guess, but I would guess that he has too many fish to fry to put his efforts into ending blessings. Besides, he has had to defend the priesthood against I would call “rogue ordinations” in our archdiocese, done in direct defiance of his authority and canon law on supposed grounds of “justice”. I don’t think he will be in a hurry to take any religious gesture away from the laity that he has the power to allow.
