What Is Holy Communion According to the Bible?

Holy Communion, according to the Bible, is the sacred meal established by Jesus at the Last Supper, when He took bread and wine and said, “This is my body” and “This is my blood.” Christians agree that Holy Communion is central to worship, but they differ on whether it is symbolic or truly Christ’s Body and Blood. The Catholic answer is that Scripture points strongly to the Real Presence of Christ in the Eucharist.

Where in the Bible Is Holy Communion First Established?

Holy Communion is first established by Jesus at the Last Supper, during the Passover meal before His crucifixion. The main biblical accounts are found in:

  • Matthew 26:26–28 — Jesus takes bread and says, “This is my body,” then takes the cup and says, “This is my blood of the covenant.”
  • Mark 14:22–24 — Jesus gives the bread and cup to His disciples and connects the cup with His blood poured out for many.
  • Luke 22:19–20 — Jesus says, “Do this in remembrance of me,” showing that this was to continue in the life of the Church.
  • 1 Corinthians 11:23–26 — Saint Paul repeats the tradition he received, showing that the earliest Christians already treated Holy Communion as sacred and apostolic.

The timing is important. Jesus instituted Holy Communion at Passover, the Jewish feast remembering Israel’s deliverance from slavery in Egypt. In the first Passover, the blood of the lamb marked God’s people and protected them from death. At the Last Supper, Jesus reveals Himself as the true Lamb of God. His Body is given, and His Blood is poured out for the forgiveness of sins.

Holy Communion is therefore not just a reminder of a meal. It is connected to covenant, sacrifice, redemption, and the Cross.

Did Jesus Mean Holy Communion Is a Symbol or His Literal Body and Blood?

Christians have long disagreed on this question. Many Protestants understand Holy Communion mainly as a symbol or memorial. Catholics, Orthodox Christians, and some other Christians believe that Christ is truly present in the Eucharist.

The Catholic view begins with Jesus’ own words. At the Last Supper, Jesus did not say, “This represents my body.” He said, “This is my body.” He did not say, “This cup represents my blood.” He said it was His blood of the covenant.

In John 6, also known as the Bread of Life Discourse, Jesus says that His flesh is real food and His blood is real drink. Many of His listeners found this teaching hard and left Him. If Jesus meant only a symbol, this would have been the perfect moment to correct them. Instead, He allowed the difficult teaching to stand.

This does not mean Catholics believe Christ is physically torn apart again at every Mass. The sacrifice of Christ on the Cross happened once for all. The Eucharist makes that one sacrifice present sacramentally. The outward appearances of bread and wine remain, but Catholics believe the reality becomes the Body and Blood of Christ.

So the Catholic answer is clear: Holy Communion is not a bare symbol. It is the true Body and Blood of Christ under the appearances of bread and wine.

What Does Saint Paul Teach About Holy Communion in 1 Corinthians?

Saint Paul gives one of the strongest New Testament witnesses to Holy Communion. In 1 Corinthians 11, Paul says he received this teaching “from the Lord” and handed it on to the Church. This shows that Holy Communion was not invented centuries later. It was part of apostolic Christianity from the beginning.

Paul describes the words of Jesus over the bread and the cup and says that whenever Christians eat this bread and drink this cup, they proclaim the Lord’s death until He comes. That means Holy Communion looks backward to the Cross, forward to Christ’s return, and inward to the believer’s communion with Him.

Paul also makes clear that Communion was not an ordinary meal. The Corinthians were treating the gathering carelessly, with division, selfishness, and lack of reverence. Paul rebukes them strongly because the Lord’s Supper is holy.

If Holy Communion were only a casual symbol, Paul’s warning would seem extreme. But if Communion truly involves the Body and Blood of the Lord, then reverence is necessary.

What Does the Bible Say About Receiving Communion Unworthily?

The Bible gives a serious warning about receiving Holy Communion unworthily. Saint Paul says that those who eat and drink without discerning the body bring judgment on themselves.

This passage is very important. Paul does not say that unworthy reception is merely rude or spiritually unhelpful. He says it is a sin against the Body and Blood of the Lord. That language strongly supports the Catholic belief that Holy Communion is not ordinary bread and wine.

This is also the biblical foundation for the Catholic practice of receiving Communion in a state of grace. Catholics should not receive Holy Communion while conscious of mortal sin. They should first go to Confession and be reconciled to God.

This is not meant to keep people away from Jesus. It is meant to protect the holiness of the Eucharist and the soul of the person receiving. Holy Communion is medicine for the faithful, but it must not be received with deliberate, unrepented serious sin.

Why Does the New Testament Call Holy Communion the "Breaking of the Bread"?

The New Testament often refers to early Christian worship as “the breaking of the bread.” This phrase appears in Acts 2:42, where the first Christians devoted themselves to the apostles’ teaching, fellowship, the breaking of bread, and prayers.

This was more than eating together. The phrase points to the Eucharistic life of the early Church. The first Christians gathered around apostolic teaching, prayer, community, and the sacred meal Jesus had commanded them to continue.

The road to Emmaus in Luke 24 also helps us understand this phrase. The risen Jesus walks with two disciples, explains the Scriptures, and is finally recognized by them “in the breaking of the bread.” This pattern is deeply Eucharistic: Scripture is opened, bread is broken, and Christ is recognized.

That same pattern remains visible in Catholic Mass today. The Church hears the Word of God, then receives Christ in the Eucharist. The structure is not accidental. It reflects the biblical pattern of Word and Sacrament.

Holy Communion, then, is not an optional extra added to Christianity later. It belongs to the faith of the apostles. Jesus established it, Paul defended it, the early Church practiced it, and Catholics continue to revere it as the true Body and Blood of Christ.
