Preparation for Holy Communion

The apostolic instruction is the root of the whole discipline: "let a man examine himself, and so let him eat of that bread, and drink of that cup" (1 Corinthians 11:28). Preparation is not a scheme for becoming worthy — the Church's own pre-communion prayer puts on every communicant's lips the confession that Christ came "to save sinners, of whom I am first." No amount of fasting makes anyone worthy of God. Preparation is, rather, a way of waking up: the Eucharist is easy to receive and easy to sleep through, and the disciplines exist so that body and soul arrive at the Chalice paying attention.

This entry is about the days and hours before communion. For what happens at the Chalice itself — approaching, the spoon, the zeon and antidoron — see receiving Holy Communion.

The most widespread norm is the eucharistic fast: nothing eaten or drunk from midnight before receiving, so that Holy Communion is the first food of the day. For evening celebrations — above all the Lenten Presanctified Liturgy — a fast from midnight is impractical, and bishops commonly direct a total fast for some hours beforehand instead. (Practice varies by jurisdiction, and the fast is routinely adjusted for small children, the sick, the pregnant, and those on medication — this is ordinary economia, arranged with one's priest, never a private heroism.) The eucharistic fast is distinct from the Church's seasonal fasting rules, though many traditions also encourage a quieter, more restrained eve — some keep the evening before with Vespers or vigil.

Prayer is the other pillar. Orthodox prayer books contain appointed prayers before communion, and fuller rules add canons and an akathist said the night before. How much of this rule a given person keeps differs by tradition and by strength — a mother of four and a monk do not carry the same rule — and is best set with one's priest rather than copied from the internet.

Here the differences among Orthodox jurisdictions are real, and it is honest to say so. In much of the Russian and broader Slavic tradition, the expectation has been confession before each communion, or at least very recently. Greek and Antiochian practice generally expects regular confession as part of a communicant's life without tying it to every single approach to the Chalice. Both agree on the essentials: grave sin must be confessed before communing, and frequent communion belongs together with a real life of repentance — the disagreement is about rhythm, not about repentance.

One preparation is prescribed by the Lord Himself and varies nowhere: peace with others. "First be reconciled to thy brother, and then come and offer thy gift" (Matthew 5:23-24). Someone nursing an unforgiven quarrel has preparation to do that no fast can replace. And a newcomer or someone returning after long absence should simply speak with the priest beforehand — every priest would rather have that conversation than see someone hover at the back in uncertainty. The disciplines are a runway, not a wall: their whole purpose is to bring you to the Chalice awake.
