Communion Explained: How Different Churches Understand the Lord’s Supper

Nearly every Christian church celebrates the Lord’s Supper, yet they understand what happens in it very differently. Here is how the major traditions see the bread and the cup.

Catholic & Orthodox

Both teach the real presence: the bread and wine truly become the Body and Blood of Christ. Catholics explain this as transubstantiation; the Orthodox affirm the mystery without defining the mechanism. The Eucharist is the center of worship.

Lutheran

Lutherans affirm the real presence too, teaching that Christ is truly present “in, with, and under” the bread and wine (the sacramental union) — without the elements changing substance.

Reformed & Presbyterian

Reformed churches teach a spiritual real presence: Christ is truly received by faith through the Supper by the work of the Holy Spirit, though not physically located in the elements.

Baptist

Most Baptists hold the memorial view: the Supper is a symbolic act of remembrance and proclamation of Christ’s death, obeyed in faith, rather than a means of grace.

Where the traditions turn in Scripture: The traditions read the same texts differently — especially John 6:51–56, Luke 22:19 (“this is my body”), and 1 Corinthians 11:23–26.

Frequently asked questions

What is the difference between transubstantiation and the memorial view?

Transubstantiation (Catholic) teaches the elements truly become Christ’s body and blood; the memorial view (Baptist) teaches they remain bread and cup and symbolize His sacrifice.

Do all churches use wine?

No. Many Baptist and evangelical churches use grape juice, while Catholic, Orthodox, and Lutheran churches typically use wine.
