Jesus first instituted Communion just before His death (Matthew 26:26–29). He instructed it to be done as a way to remember what He would do on the cross (Luke 22:19) and that He would return (1 Corinthians 11:26). Because of this, Communion is not an optional practice.
While Scripture does not provide a specific timeline, it indicates that Communion was regularly practiced in the early church. Some interpret Acts 20:7 as indicating the early church did it weekly. However, references to breaking bread may refer to regular meals rather than to Communion. Even if it’s a Communion reference, it simply describes what happened at that time and is not a command for how often it must be done. First Corinthians 11:17–34, the most cited Communion passage, assumes it’s a regular occurrence while not mentioning a specific frequency.
Because a specific cadence was not specified, evangelical traditions do it regularly, but on differing schedules. Some do it weekly, while others do it monthly or with some other discernible regular pattern. They all practice it to remember what Jesus has done and will do.
Jesus gave us Communion so we would remember Him. This includes not just what He has done (die on the cross) but also what is to come (be with Him in eternity). Scripture lists only two “ordinances” (commands) that all members of a church are to participate in: Communion and Baptism. In either case, neither He nor the rest of the biblical authors specify exactly when or how they must happen. This means that, regarding Communion, churches throughout history have varied in how often they take Communion and in what elements are used (be it wine or juice, bread or crackers, and so forth). That flexibility fits within Scripture because the heart of it isn’t the act of taking Communion but the act of remembering Jesus.
Below are a couple of general observations about Communion that may be helpful. First, a church is not a biblical church if it never performs Communion. This is because Jesus commanded us to do it. Second, Communion is the practice of remembering what Jesus did for us. This means it is specifically for believers. No one is saved through Communion. They take Communion to remember the One who saved them. Third, because the “when” and “how” are not commanded in Scripture, we need to be gracious with other believers who attend churches with a different Communion tradition than the one to which we are accustomed. Fourth, the act of Communion is one to be done in communion with other believers. Except in extraordinary circumstances, it is expected to be taken in person with other believers. Fifth and finally, it should be an act of joy! Communion is often, and rightly, taken with great introspection. However, Jesus has already borne all of a believer’s sins, so it should be a time marked by great gratitude for what He has done and will do.
Communion is less about the bread and cup and more about the heart—each time we take it, we step into the story of Christ’s sacrifice and the hope of His return.
