Are Catholics and Orthodox in Communion?
Not fully — there is no shared altar, and Rome’s primacy is still refused. But the bond is real: one baptism, valid sacraments, a faith all but identical. The word is “imperfect communion.”
Not fully — there is normally no shared Eucharist, and the papacy is still not accepted. But communion comes in degrees, and the bond is real: one baptism, valid orders, a true Eucharist, a faith all but identical. The Catechism says the gap “lacks little.” The honest word is real but imperfect communion.
Are Catholics and Orthodox in Communion?
It feels like a yes-or-no question, and most people reach for “no.” By the everyday test — are we at the same altar? — that is right: there is normally no shared Eucharist between Catholics and Orthodox, and the Orthodox do not accept the papacy. But Catholic teaching does not treat communion as a single on-off switch. It comes in degrees. By that measure the honest answer is neither “no communion” nor “full communion,” but a third thing: real but imperfect communion.
The bond is real because baptism makes it so. Vatican II teaches that those “who believe in Christ and have been truly baptized are in communion with the Catholic Church even though this communion is imperfect.” Schism wounds that bond; it does not erase it. And with the Orthodox the bond runs deeper than with anyone else — valid bishops, a valid priesthood, a true Eucharist, and a faith all but identical: the Trinity, the Incarnation, the Mother of God, the seven councils, the communion of saints.
How deep? The Catechism puts a measure on it that should stop a reader cold: with the Orthodox “this communion is so profound that it lacks little to attain the fullness that would permit a common celebration of the Lord’s Eucharist.” Lacks little. This is why Catholic law can permit, in defined cases of need, a Catholic to receive Communion, Confession, and Anointing from an Orthodox priest — a thing unthinkable toward a body whose Eucharist Rome did not hold to be real. (In practice the Orthodox, by their own discipline, will usually decline to commune a Catholic in return; the permission runs one way.)
So the communion is imperfect, not absent — and what makes it imperfect is precise. It is chiefly the papacy: the Orthodox do not accept the primacy of the Bishop of Rome, and so, as a rule, the two Churches do not yet share the one altar. Two honest cautions belong here. “Lacks little” is not “lacks nothing” — the gap is real and grave. And “imperfect communion” is a Catholic way of speaking; many Orthodox would decline the word entirely, holding the relationship to be one of separation. The bond is genuine; so is the wound.
