Valid Eucharist and True Particular-Church Status identifies the genuine Eucharist, celebrated through a valid episcopal and priestly ministry in Apostolic Succession, as a decisive sacramental bond by which a separated Eastern body remains a true Church.[1]
Why the Eucharist is an ecclesial criterion
The Eucharist is not an isolated sacred object produced inside an otherwise religious association. It is the sacramental memorial of Christ's sacrifice, the communion of his Body and Blood, and an action of the Church presided over by a bishop or priest who acts in the ministerial priesthood. A true Eucharist therefore presupposes and manifests a real sacramental constitution of the Church.
Communionis notio teaches that in every valid Eucharistic celebration the one, holy, catholic, and apostolic Church becomes truly present. Dominus Iesus accordingly names separated Eastern bodies true Particular Churches because Apostolic Succession and a valid Eucharist join them to the Catholic Church by the closest bonds even though Full Communion is absent.[2][3]
A valid episcopate and priesthood
The Eucharist requires a validly ordained bishop or priest. Apostolic Succession sustains the episcopate from which priestly ministry is received. A communal meal, a rite led by an unordained president, or a service conducted by a minister whose body lacks Valid Holy Orders cannot acquire Eucharistic validity through sincerity or through recitation of Catholic words alone.[4]
The genuine and integral Eucharistic mystery
Catholic classification concerns the genuine and integral substance of the Eucharistic mystery: sacrificial memorial, Real Presence, ordained presidency, valid elements, form, intention, and ecclesial celebration. Selective Eucharistic vocabulary does not supply what a community's sacramental constitution lacks. The criterion is objective and corporate rather than a ranking of devotional warmth.
True Church, but wounded communion
A valid Eucharist does not make Full Communion automatic. The separated Eastern Churches lack communion with the Bishop of Rome and do not accept the Catholic doctrine of his universal primacy. Catholic teaching calls this lack internally constitutive: communion with the Universal Church and her visible head is not an external alliance appended to a complete local unit.[5]
The same doctrine forbids denying what remains. Their bishops and priests are real ministers; their Eucharist is the Eucharist; the Church of Christ is present and operative in them. Particular-Church status and wounded communion must be affirmed together. Either half alone falsifies the Catholic judgment.
Limits of the criterion
The existence of a person with arguably valid Orders inside a Western Ecclesial Community does not necessarily give that whole body a stable sacramental episcopate or integral Eucharistic constitution. Corporate continuity, recognized ministry, doctrine, and ordinary sacramental life must be assessed. A stray lineage is not equivalent to a Church ordered around bishop and Eucharist.
Validity cannot be inferred from the title Orthodox, Catholic, apostolic, or ancient. Competent Catholic judgment and exact evidence govern. Where they are established, the Catholic conclusion is stated plainly; where an individual rite or marginal body remains doubtful, the uncertainty belongs to that case and must not be projected onto the recognized Separated Eastern Churches.
