Imagine a first-century church (one of the churches Paul and Barnabas planted, for instance), and they’re arguing over the wine they use for the Lord’s Supper. Some people have complained, “why are we using this cheap wine, when we could just as easily get a nice cabernet?” Perhaps they were self-conscious when relatives would visit from Rome and the communion wine tasted like vinegar. But when they then switched to a better wine, some complained about the money they were spending on it; still others said that they couldn’t properly focus on the gravity of Christ’s death while they were enjoying a fine wine.
What do you think Paul would have said in a letter to this church? Would he have said something like, “haven’t I taught you anything about grace? Seek to outdo one another in showing honor and deference to the needs and preferences of others. Think of others more highly, and more often, than you think of yourself…” I bring this thought experiment up because I see many modern churches having similar arguments over the bread we use for communion.
But when Paul says “do all things without grumbling,” he means all things, and he means no complaining. When we have the capacity to complain and grumble about the culinary quality of the elements we use for Communion, we not only show that we have completely failed to internalize and apply the lessons about grace the Scripture teaches us, but we evidence a selfish, self-centered attitude that is in line with the attitude for which Paul rebuked the Corinthian church, saying that because of the way they were treating one another over the issue of Communion, they “make it not the Lord’s Supper.”
In other words, you’re missing the whole point. You’ve sat down at the table of fellowship only to flip over the table and spoil the Supper. This is a meal that proclaims and celebrates the fellowship we have with Christ, and because of our union with Christ then also the fellowship we have with one another as brothers and sisters in Christ. And we profane the very purpose of the communion meal when we can’t see past our own preferences and felt needs, and instead allow selfish and discontent thoughts into our hearts over the very practice that Christ instituted to be not only a remembrance of his death and resurrection, but a celebration of the new life in union with him and in fellowship with our new family that we now have.
Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord. Let a person examine himself, then, and so eat of the bread and drink of the cup. — 1 Corinthians 11:27-28
