Why don’t a lot of ppl that go up and recive the bread don’t drink of the cup.arent we suppose to drink of the cup to

Body of Christ. Unfortunately not all of us are able to to take communion.

So a lot of them don’t like it,so why don’t they use grape juice or even cranberry juice

It's not because they don't understand they could be coming down with a cold therefore they don't want to give it to.

Yes you are supposed to drink the wine too but some people don't like it or dont understand.
