I once heard someone say that they just partake in Communion (like normal) and eat the bread and drink the wine even though they're coeliac.
They quoted that:
I'd be interested on your perspective with regard to this particular matter...
to me, communion is about atonement, not suffering. i don't remember the part in the bible where it says Jesus had D for me. but whatever floats your boat.
i bring my bread in a little snackie bag to church and take it out and eat it at the altar where everyone else is receiving the host and the pastor blesses it along with all the regular bread. last week i forgot it in the pew and had to dash back to get it and everybody smiles and asks me after the service "oh, you forgot to bring up your bread didn't you?" i hope everyone has such love at their church as i have in ours. they are truly our church family
