Wouldn’t know. Never seen it in a Presbyterian church, but I only attend good conservative churches with people who take it seriously.
The caliber of parents I see at mass? Some of ‘em I bet would hand the kid a wafer if they thought they could get away with it. I mean, they aren’t teaching them anything else - like sitting still, being quiet, not eating snacks, not playing with toys. It’s about the parenting and not the denomination I think although having servers who can prevent three year olds from receiving certainly helps.
I think it’s great that you attend mass!
but it’s not a “wafer”
