The Eucharist and the Real Presence

The Catholic response

When Jesus taught on the Bread of Life in John 6, his listeners took him literally and were scandalized — 'How can this man give us his flesh to eat?' — and rather than clarifying he was speaking symbolically, Jesus intensified the language, using the graphic Greek verb 'trogein' (to gnaw/munch) and insisting 'unless you eat the flesh of the Son of Man and drink his blood, you have no life in you' (John 6:53), so severe that many disciples left him, yet he let them go rather than soften a merely symbolic point. At the Last Supper he does not say 'this represents my body' but 'this is my body, which is given for you' (Luke 22:19), and Paul warns that anyone who eats the bread or drinks the cup 'in an unworthy manner will be guilty concerning the body and blood of the Lord,' language that makes no sense for a mere symbol (1 Corinthians 11:27). Unlike 'I am the door,' where nobody in the crowd was confused into thinking Jesus was made of wood, in John 6 the crowd clearly understood him literally and he did not correct them. Every extant witness from the sub-apostolic age — Ignatius of Antioch around AD 107, Justin Martyr around AD 155, and later Irenaeus and Cyril of Jerusalem — describes the Eucharist unambiguously as the true flesh and blood of Christ, with no rival symbolic interpretation appearing in Church history until the medieval Berengarian controversy, over a thousand years later.

Mistakes to avoid

• Failing to address John 6:63 directly, leaving it as an apparent unanswered contradiction.
• Describing the Real Presence in crudely physical terms that invite the 'cannibalism' caricature rather than using 'substance/accident' language.
• Not noting the unanimous, unbroken patristic witness as historical evidence against a late invention.
