The Eucharistic Fast
"Why do Catholics fast before Communion?"
The Short Answer
Catholics are required to fast for at least one hour before receiving Holy Communion. This discipline prepares body and soul for the sacred encounter with Christ in the Eucharist.
Quick Overview
Before receiving Jesus in Holy Communion, Catholics fast for at least one hour—no food or drink except water and medicine. This might seem like a small thing, but it's meaningful. It says: 'What I'm about to receive isn't ordinary food. My body will be a temple for Christ Himself.' In the old days, the fast was from midnight! The one-hour fast is gentle, but it still helps us approach Communion mindfully rather than casually. It's a small sacrifice that expresses reverence for what we're receiving: Jesus, Body and Blood, Soul and Divinity.
Biblical Evidence
What the Scriptures say
"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. But let a man prove himself: and so let him eat of that bread."
Why This Matters
Paul calls for self-examination and worthy reception. The fast is part of that preparation—showing reverence.
What the Church Teaches
Official Catholic doctrine
Canon law requires a one-hour fast from food and drink (except water and medicine) before receiving Communion (Canon 919). The elderly, sick, and their caregivers are exempt.
