Andrew Brown asks a good question
The question he asks is "Do we really need so many 'Eucharistic Ministers'?" Excerpt:
What’s the point of all these assistants? The Catholic Church does allow for what it calls an extraordinary minister of Holy Communion, in cases when the priest is not available. But there is absolutely no need to have five extra ministers, giving Holy Communion under both kinds, as I saw this morning in an ordinary parish church, two thirds full, with a perfectly capable parish priest.
I can’t help thinking all these ministers are there just to give the more assertive parishioners something to do – so that they feel as though they’re joining in. I should think the priest is often bullied into allowing it, and daren’t refuse. As for ordinary Catholics, most of them probably find the extra helpers irritating, but are too polite to say.
All good points in his article. One priest I knew told me he runs into EMs who seem to feel they have some sort of "right" to distribute communion and they get hurt feelings when they aren't needed.
In my experience a lot of EMs seem distracted by ephemera. One time I was asked a question by a very young man distributing communion immediately after I had received communion. What was he thinking? I just shrugged.
I don't know if I'm "too polite to say" anything as Brown suggests. I just consider that there are too many moral crises in the church and the world to obsess about some of these matters. But liturgical abuses certainly don't help the situation.
