I think the Eucharistic Ministers have a lot more respect for the Eucharist than some of the people they are giving it to. The ones I know take this very seriously indeed (including my husband). If they are looking irreverent or poorly trained, that is on the pastor and liturgical coordinator.
But if you think it’s a disorderly, excessive crowd up there on the altar, I guess that needs to be addressed by your pastor.
I am guardedly hopeful regarding the mass. Our parish has scaled back over the years regarding people on the altar. (No more teenage youth group up there, for example). I don’t think it has to be a downward spiral for solemnity. Especially if the bishop sets some standards that pastors must follow.
No, I honestly cannot say the group is disorderly — not counting the college-aged girl that was up there recently in what looked like sprayed on clothes — but the number is excessive.
We have a very small parish and one priest, and I have never been to a Mass there for which the church was filled — except for Easter and Christmas. Communion could be distributed by a much smaller group of extraordinary ministers in a short amount of time. Usually the church is at 1/3 or less of capacity.
