This is what we refer to as a “non-dogmatic” issue. Dogmatic, on the other hand, refers to something that is incontrovertibly true – something that cannot be negotiated, but must be accepted. So when we say that a teaching of the Bible is dogmatic, then it must be accepted and taught, no negotiations or beating around the bush, as they say. A few examples of something biblically dogmatic would be: the gospel, the inspiration of Scripture, the Trinity, the deity of Jesus Christ, and things like this that would radically change the message and validity of Christianity if they were altered even in the least.
But there are also plenty of non-dogmatic issues today. Some of these are: proper church attire, contemporary vs. traditional music in the church, eldership/deaconship, and others like these. Issues that fall into this category can alter and change depending on your local congregation – and they are no more or less biblical than the church that handles those issues differently. For example, it is just fine if a church allows blue jeans and t-shirts in the worship service. There is no biblical command that says you must wear a suit and tie to worship. But there may be a more traditional church that says you should wear your “Sunday best.” That is also fine. Falling under this category of non-dogmatic is how frequently and individual or church should partake of the Lord’s Supper (or Communion).
The Bible doesn’t specify how often you should partake of the Lord’s Supper, it only specifies that you should partake of it, in a proper manner, and that you understand and apply its meaning. It doesn’t matter if you partake of it once a year, once a month, or once a week. What matters most is that you do it in remembrance of Jesus, understand its significance, and partake of it in the correct manner.
The instructions we have about the Lord’s Supper are found in 1 Corinthians 11, where Paul states: “For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, “This is my body which is for you. Do this in remembrance of me.” In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes” (vv. 23-26, emphasis mine).
Paul quotes Jesus in this passage, and as far as how often we should partake of the Lord’s Supper, Jesus only requires “as often as you drink it.” That is the only time frame we have. This assumes that we are partaking of the Lord’s Supper, and it implies that it should be done time and time again. The tone used in this part of the passage doesn’t indicate that it should only be done once, but it the tone in this passage also doesn’t indicate that it should be done constantly. Only “as often” as you do it.
The important thing to remember is that the Lord’s Supper is a sacred time to remember the Lord Jesus and the significance of His substitutionary death on the cross, and that we have received it. The Roman Catholic Church teaches that the Lord’s Supper, referred by them as the Eucharist, actually becomes the body and blood of Christ. That might be a good example of when a non-dogmatic issue becomes a dogmatic issue. When something that is considered non-dogmatic is altered to the point where it conflicts with other Bible teachings, then it needs to be reexamined and reinterpreted in light of the other teachings of Scripture. Nowhere in Scripture does the Bible teach or even imply that the Lord’s Supper transfuses into the actual blood and body of Christ that we must receive for salvation. When something non-dogmatic conflicts with what is dogmatic, it is no longer a non-dogmatic issue.
The Lord’s Supper is a beautiful symbol, and a time of remembrance and thanksgiving. We eat the bread symbolizing that we have partaken of Jesus Himself, the Bread of Life (John 6:35), and we drink the juice (or wine) symbolizing that we have received His blood as atonement for our sins. Nothing in Scripture about the frequency of doing so, only “as often” as we do it.
