Catholic Ecclesiological Classification is the Catholic Church's ordered vocabulary for describing the Church of Christ, Catholic communion, other Christian Churches and ecclesial communities, and non-Christian religions without treating unlike relations as equivalent.

A grammar of communion

Catholic Ecclesiological Classification begins with the one Church of Christ, not with a neutral collection of denominations. That Church subsists in the Catholic Church, while many Elements of Sanctification and Truth are truly present outside her visible structure. Those elements create real relations to the Church and impel toward Catholic unity; their presence does not turn divided bodies into equal branches of an invisible whole.[1]

Communion is differentiated rather than binary, but it is not an official percentage scale. Baptismal Communion is the sacramental hinge for persons. Apostolic Succession, a valid episcopate, the Eucharist, profession of faith, and ecclesiastical governance further determine the kind and fullness of an ecclesial body's communion. These objective distinctions do not measure an individual's sincerity, moral worth, culpability, or final salvation.[2]

Full Catholic communion

Full Communion joins the baptized to Christ within the Catholic Church's visible structure through the bonds of the profession of faith, the sacraments, and ecclesiastical governance. It embraces the Latin Church and all Eastern Catholic Churches sui iuris with equal Catholic dignity. Liturgical, canonical, spiritual, and theological diversity within that communion is not a lower grade of Catholicity.[3][4]

True Churches without full communion

Separated Eastern bodies that preserve Apostolic Succession, a valid episcopate, priesthood, and Eucharist are true Particular Churches. The Church of Christ is present and operative in them, but their condition is wounded because communion with the successor of Peter is an internal constitutive principle of the fully catholic Particular Church, not an optional external alliance.

Christian ecclesial communities

Communities issuing from the Reformation that have not preserved valid episcopal succession and the genuine Eucharistic mystery are Ecclesial Communities rather than Churches in the proper sense. Where their baptism is valid, their members are Christians in Imperfect Communion and possess real ecclesial goods. The adjective ecclesial affirms that reality; it does not silently recognize a sacramental constitution that is absent.[5]

Non-Christian religions

A body whose defining faith is non-Trinitarian and whose initiatory washing is not valid Christian baptism is not an Ecclesial Community in the technical ecumenical sense. It belongs under Non-Christian Religion even if its proper name or self-description uses Christian words. This is why the Latter-day Saint movement and Jehovah's Witnesses must not be placed in the same ecclesiological class as baptized Protestant communities.[6]

Classifications that must not be collapsed

Particular Church, Local Church, and Church sui iuris answer different questions. A Particular Church is ordinarily a diocese or eparchy gathered around its bishop. Local Church is often a theological synonym, though wider informal uses require context. A Church sui iuris is a self-governing Catholic ecclesial body recognized by supreme authority and may contain many Particular Churches—or, in a small case, only one.[7]

Validity of Holy Orders is distinct from canonical liceity, lawful ministry, or Full Communion. A validly ordained bishop outside Catholic communion may perform a sacrament validly but illicitly. Conversely, historical age, the word bishop, or an asserted succession chart does not establish validity without the sacramental facts and the Church's judgment.

Persons, bodies, and proper names

The ecclesial status of a body and the spiritual condition of a person are not interchangeable. A baptized Christian may possess grace and holiness within an Ecclesial Community that lacks valid Orders. A nominal Catholic may break visible communion through apostasy, heresy, or schism. An unbaptized person may be ordered to the people of God and moved by grace without thereby belonging to Christian ecclesial communion.

An organization's legal proper name does not determine its theological classification. The word Church in the name Church of Jesus Christ of Latter-day Saints does not make that body a Church in the proper sense. Likewise, informal use of denomination, tradition, communion, or movement does not replace the exact Catholic classification where a doctrinal distinction is at issue.[8]
