The Real Presence in the Eucharist

"Does the Catholic Church really believe the Eucharist is Jesus' actual body and blood?"

4 Scripture passages2 objections answered2 Church Father quotes

The Short Answer

Catholics believe that during Mass, the bread and wine truly become the Body and Blood of Jesus Christ. This is not merely symbolic—it is a real, substantial change while the appearances of bread and wine remain.

Quick Overview

Imagine if Jesus walked into your church and offered to let you receive Him—not just spiritually, but truly present. That's what Catholics believe happens at every Mass. When the priest says 'This is my body,' ordinary bread becomes extraordinary: it becomes Jesus Himself.

Biblical Evidence

What the Scriptures say

John 6:51

"I am the living bread which came down from heaven. If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh, for the life of the world."

Why This Matters

Jesus explicitly says the bread He gives IS His flesh. He uses 'sarx' (flesh), the most physical, concrete term possible.

John 6:53-56

"Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you... For my flesh is meat indeed: and my blood is drink indeed."

Why This Matters

Jesus uses 'trogon' (to gnaw, to munch) emphasizing physical eating. When disciples left, He didn't clarify it as symbolic.

Matthew 26:26-28

"Take ye, and eat. This is my body... This is my blood of the new testament."

Why This Matters

At the Last Supper, Jesus says 'This IS my body'—not 'this represents' or 'this symbolizes.'

1 Corinthians 11:27-29

"Whosoever shall eat this bread, or drink the chalice of the Lord unworthily, shall be guilty of the body and of the blood of the Lord."

Why This Matters

You cannot be guilty of profaning a mere symbol. This only makes sense if the Eucharist truly is Christ's body and blood.

What the Church Teaches

Official Catholic doctrine

The Church teaches transubstantiation: the whole substance of bread becomes Christ's body, and wine becomes His blood (CCC 1376). The Eucharist is the source and summit of Christian life, containing Christ Himself (CCC 1324).
