The Eucharist or what many call Communion has different forms. The Catholic celebration is different from what protestant churches typically do with a tidbit of cracker and a thimble of grape juice. The celebration may be weekly, monthly, or only on special occasion.
All practices have one thing in common: it is a liturgy, a form that is supposed to have spiritual importance.
I wonder if a ritual is what Jesus intended when he ate the Passover meal with his disciples just before he was arrested. The common ancient practice used leavened bread and wine mixed with water because that’s what was available and used with almost every meal, except for Passover, of course.
If the association was with Passover, the early Christians would have celebrated once a year, not every time they got together. If it had been a symbolic act, the apostle Paul wouldn’t have had to reprimand people for their focus on eating and drinking so much that they became fat and drunk (1 Corinthians 11:21). A few verses later, the apostle Paul seems to be emphasizing what Jesus wanted whenever we ate together—to remember Christ and make him a part of our gathering (1 Corinthians 11:23–33).
Perhaps, Jesus was giving people a common, everyday practice to use in remembering him—something like saying, “When you look at your watch, don’t just see the time, but think about me and what I have done for you.” In that case, if he was sitting with us at a Mexican restaurant today, he might say, “Every time you grab a chip, remember by body that was given for you. Whenever you dip the salsa, remember my blood that was shed for you.”
Maybe we could have a “look at your watch” liturgy or a “lift up your salsa-laden chip” liturgy. No, that would be dumb. But how dumb would it be, if it caused us to remember Christ and brought us together in unity?
