Question: "How often should the Lord's Supper / Communion be observed?"
Answer: The Bible nowhere instructs us how often we should take communion. 1 Corinthians 11:24-26 records the following instructions for communion: “…the Lord Jesus in the night in which he was betrayed took bread; And giving thanks, He broke it and said, ‘Take, eat; this is My body, which is broken for you; this do in remembrance of Me.’ In the same way He took the cup also, after supping, saying, ‘This cup is the New Covenant in My blood; as often as you drink it, do this in remembrance of Me.’ For ‘as often as you eat this bread and drink this cup, you show’ the Lord's death until He shall come.” This passage gives all the instructions we need to perform the rite of communion and to understand the significance of what we are doing.
The bread which He broke in half represents His body which was broken on the cross for us. The cup represents the blood He shed on our behalf, sealing a covenant between Him and us. Each time we perform the communion ritual, we are not only remembering what He did for us, but we are “showing” it as well to all who watch and all who participate. This is a beautiful and graphic picture of what happened at the cross, what it means, and how it impacts our lives as believers.
It would seem, then, that since we take the Lord’s Supper to remember Christ’s death and shed blood, we should take it fairly often. Some churches have a monthly Lord’s Supper service, others do it bi-monthly, others weekly. Since the Bible does not give us specific instruction as to frequency, there is some latitude in how often a church should observe the Lord’s Supper. It should be often enough to renew focus on Christ, without being so often that it become routine. In any case, it’s not the frequency that matters, but the heart attitude of those who participate. We should partake with reverence, love, and a deep sense of gratitude for the Lord Jesus, who was willing to die on the cross to take upon Himself our sins.
