Holy Communion, also referred to as the Lord’s Supper (1 Cor 11:20) or the Eucharist ("thanksgiving," from the Greek εὐχαριστία), is a sacrament instituted by Jesus Christ on the night before His crucifixion (Matt 26:26-29; Mark 14:22-25; Luke 22:14-20). Holy Communion is the corporate act of partaking in bread and wine as symbols directly tied to Christ’s body and blood. These elements are thus a visible promise of God’s grace, a memorial of Christ’s sacrifice, and a pledge of the New Covenant in his blood. Across traditions Communion is also seen as a means of grace that nourishes believers spiritually (John 6:51-58) and as a corporate proclamation of Christ’s death until he comes (1 Cor 11:26).

There are four main views of Holy Communion, all centred around the Presence of Christ at the time of partaking. Is Christ physically or spiritually present, or is it simply an act of remembrance? The main four views are as follows:

• Transubstantiation (Roman Catholic)
  • The bread and wine change into the actual body and blood of Christ, though they still appear as bread and wine.
• Consubstantiation or Sacramental Union (Lutheran)
  • Christ’s body is with and under the bread but does not replace it.
• Spiritual Presence (Calvinist)
  • The bread remains bread; Christ’s presence is real, but spiritual, not physical.
• Memorialism (Zwinglian)
  • The Lord’s Supper is purely symbolic, with no real presence of Christ.

Key Themes

Instituted by Christ

Jesus established the Supper on the night He was betrayed, commanding His disciples to "do this in remembrance of me" (Luke 22:19-20). This act of obedience continues in the church today.

New Covenant Sign

The bread and cup signify the new covenant, sealed by Christ’s blood (Luke 22:20; Matt 26:28), echoing the covenantal pattern of blood-ratified promises (Exod 24:8; Heb 8:6-13).

Memorial & Proclamation

Communion is a remembrance of Christ’s once-for-all sacrifice (Heb 7:27; 9:28), but it is more than mental recollection. In partaking, we proclaim His death "until he comes" (1 Cor 11:24-26), participating in a re-presentation of the gospel.

Sharing in Christ’s Body & Blood

Paul describes the bread and cup as a "participation" in the body and blood of Christ. Not in the elements alone, but in Christ Himself (1 Cor 10:16). This suggests a real, spiritual encounter with the risen Lord, mediated by the Holy Spirit.

Forgiveness of Sins

Jesus’ words, "given for you" and "poured out for many for the forgiveness of sins" (Luke 22:19; Matt 26:28), ground the Supper in the saving power of His atoning death. Communion visibly declares the gospel: that Christ died for sinners.

Spiritual Nourishment

Christ is the true "bread of life" (John 6:35) and feeds His people through this sacrament. Augustine says the elements are "visible words" through which invisible grace is communicated. Communion strengthens faith, deepens holiness, and fosters love (John 6:63).

Church Unity

Communion is a communal meal. "We who are many are one body, for we all partake of the one bread" (1 Cor 10:17). Communion expresses and cultivates the unity of the church and calls believers to discern not only Christ’s body but the body of believers (1 Cor 11:29).

Eschatological Anticipation

The Lord’s Supper points forward to the marriage supper of the Lamb (Rev 19:9). Each celebration is a foretaste of that final feast, orienting the church toward the return of Christ (1 Cor 11:26; Mark 14:25).

The Real Presence of Christ in Communion

The Bible repeatedly affirms that Christ is truly present in the partaking of Communion by faith. The sacrament is more than simple memorial/remembrance. Jesus' words "This is my body…this cup is the new covenant in my blood" are not metaphors but are straightforward statements. Similarly, Paul speaks of "sharing in the body of Christ" by the bread we break and "sharing in the blood of Christ" by the cup (1 Cor 10:16). The language explicitly refers to real fellowship or communion (Greek koinōnia) with Christ.

How Christ's presence is received is the primary point of difference among various views of Communion. Some hold that Christ is present "in, with, and under" the elements, while others believe we "spiritually ascend" to Him in Communion. Yet both affirm the key truth: Christ is truly present. In other words, Christ is truly present in the taking of Communion by faith.

More than Simple Memorial

Christ commands that Communion should be taken "in remembrance of me." Some have correctly emphasised this remembrance, but in doing so have neglected the language of presence in the texts. Jesus did not teach that "this represents my body" and Paul did not teach that we only remember Christ but that we participate in Christ's body and blood (1 Cor 10:16-17). If Communion is only a symbol, then John 6's language about eating Christ's flesh makes little sense and becomes a barrier rather than a promise. Furthermore, a symbol would not result in illness and death as a result of unworthy participation (1 Cor 11:27-30).

In practice, denying any real presence can shrink the sacrament to a social meal or lecture, rather than a means of grace. Scripture seems to envisage more than mere memory: it promises an effectual meeting with Christ. In fact, communion is the only explicit promise of Christ's presence tied to physical elements.

Not the Literal Body & Blood of Christ (the Roman Catholic view)

Affirming the Real Presence of Christ does not necessitate the physical change of bread to flesh and wine to blood, as the Roman Catholics believe. This belief is rooted in Aristotelian metaphysics (substance/accidents), a philosophical category that is foreign to Scripture. The Bible never speaks of a change of essence in the elements. If Christ had intended a literal change in the bread and wine, Jesus’ repeated command to "eat" and "drink" would be criticised by followers (we taste the same bread; how could it literally become flesh?). Additionally, Christ ascended bodily into heaven and remains at God's right hand. His human nature is not omnipresent, and therefore cannot be physically present.

In any case, Christian faith does not need to depend on Aristotelian metaphysics. We can hold that Christ is really present without asserting a mysterious change of substance.

Communion as Covenant Community

The Lord’s Supper is fundamentally communal. It is a meal shared by the Church’s members, reflecting the one body of Christ. Paul said that "there is one bread; we who are many are one body" (1 Cor 10:17). Communion calls us to unity across our differences: whether Catholic, Lutheran, Reformed or others, all sit at the same table as brothers and sisters. By partaking together, the church publicly declares its common faith in Christ’s atoning death and its bond to one Lord. This is why Communion is often called the sacrament of unity.

Yet Scripture also warns that this unity must be genuine. In 1 Corinthians 11:27-30, some believers faced judgment, became sick, and even died, because they partook "in an unworthy manner." Specifically, they excluded fellow believers from the taking of Communion. They failed to recognise the body of Christ both in the elements and in the gathered Church. This is what it means to "discern the body" (v. 29): to examine our hearts, repent of sin, and forgive one another before coming to the Table. The Lord’s Supper is a sign of the new covenant, but also a call to reconcile with our brothers and sisters as members of one body.
