I hold the host up so I am looking in their eyes just past the elevated host. Every now and then I take a bit of extra time to pick up the host out of the ciborium if a sense the person needs a moment to settle and focus.
I have only experienced this once in our parish from an EMHC who was rather heavy handed in general.
Ouch. We had one visiting priest (my RCIA instructor from years before!) who rolled his eyes while giving communion to a number of people, including me. He has not been back.
It’s a BIG DEAL!
Indeed. I watch for two things. When I say “The Body (or Blood) of Christ”, I will give it a second or two. Sometimes that will illicit a “thank you” or silence. If it does, I will say “The Body (or Blood) of Christ” followed by “amen” making careful (but never threatening or severe) eye contact. Very few don’t catch on and say “amen.” For the few that have not, I simply say “the correct response is amen” and that has always done the job.
The second thing are the “grabbers” (if they are receiving in hand.) I will simply say “please put your hands together, palms up to receive the sacrament.” It has always worked.
Two overall things is to smile and to never ever rush.
