There are a variety of ways that churches do communion. I have spent my entire life in the United Methodist church and we typically do communion once a month. In all of the communion services I have participated in, we have always gone to the front of the church to be served. Beyond that, there are many ways that churches serve the bread and wine. The United Methodist churches that I have gone to always use grape juice, many times served in the miniature shot glasses (I’m sure there is an official term for these but this is what I have always called them). These glasses were actual glass in the church I grew up in and had to be cleaned between uses. They also used broken up saltine crackers for the bread. I remember our church upgrading to the communion crackers (comedian Dane Cook refers to them as Jeez its) and eventually using disposable shot glasses.
