Communion (also called the Lord’s Supper) is a church practice in which believers eat bread and drink from the cup as Jesus instructed. It is a physical, shared act meant to point to spiritual realities—especially who Jesus is and what He accomplished through His death and resurrection.

Christians take communion because Jesus Himself established it for His followers. At the Last Supper He gave bread and the cup new meaning tied directly to His coming sacrifice: “This is My body, given for you; do this in remembrance of Me.” And, “This cup is the new covenant in My blood, which is poured out for you.” (Luke 22:19–20)

The early church continued this pattern as part of normal Christian worship and life: “They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer.” (Acts 2:42)

Communion is a repeated, tangible reminder of the heart of the Christian message: Jesus gave Himself for sinners. The bread and cup are not random religious symbols; they are deliberately tied to His body and blood, emphasizing that salvation is not achieved by self-improvement or religious effort, but by Christ’s saving work.

That is why Jesus connected communion to remembrance—believers are meant to look back and stay anchored in what actually saves: the cross.

Communion is not only personal reflection; it is also a public statement. Scripture says that in taking the bread and cup, Christians are announcing something: “For as often as you eat this bread and drink this cup, you proclaim the Lord’s death until He comes.” (1 Corinthians 11:26)

So communion looks in two directions at once:

◇ Backward to the historical death of Jesus for sin

◇ Forward to His promised return and the completion of His kingdom

Communion also expresses spiritual fellowship—both with Christ and with other believers. Paul describes the cup and bread as a “participation” in Christ: “Is not the cup of blessing that we bless a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ?” (1 Corinthians 10:16)

It also highlights unity among believers: “Because there is one loaf, we who are many are one body; for we all partake of the one loaf.” (1 Corinthians 10:17) Communion is one of the clearest ways Christians say, together, “We belong to the same Savior, and we are part of the same people.”

Jesus called the cup “the new covenant in My blood” (Luke 22:20; 1 Corinthians 11:25). A covenant is a binding commitment. In biblical terms, the “new covenant” means God’s promised rescue and restoration accomplished through Christ—real forgiveness, a changed heart, and a secure relationship with God founded on Jesus’ sacrifice rather than human performance.

Communion is taken, in part, to remember and reaffirm that confidence: forgiveness is grounded in Christ’s blood, not in personal worthiness.

Because communion is meant to honor Christ and reflect real faith, Scripture warns against treating it casually or hypocritically. “Whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. Each one must examine himself before he eats of the bread and drinks of the cup.” (1 Corinthians 11:27–28)

This self-examination is not about being “good enough,” but about honesty before God—repentance rather than pretense, and reverence rather than routine.

Communion points to Christ’s sacrifice; it does not repeat it. The Bible presents Jesus’ offering as completed and sufficient: “And by that will, we have been sanctified through the sacrifice of the body of Jesus Christ once for all.” (Hebrews 10:10) Communion keeps that finished work central, reminding believers that the payment for sin has already been made.

Because communion is an acted confession of trust in Christ, many churches teach that it is for those who have personally turned to Jesus in faith. For someone still searching, being present and observing can still be meaningful: it shows, in a simple form, what Christians believe saves—Christ’s body given and blood poured out.

Christians continue taking communion because it keeps the gospel at the center of worship and discipleship. It repeatedly brings believers back to what Christianity is fundamentally about: Christ’s death for sinners, the forming of a redeemed people, ongoing repentance and faith, and the hope of His return.
