One and Unique Church is the Church of Christ confessed in the Creed, founded as one enduring visible and spiritual communion and concretely subsisting in the Catholic Church.

Unicity is a revealed property

The Church's oneness is not an aspiration added after denominational division. Christ founded one Church, gave one apostolic faith and Baptism, and entrusted visible pastoral unity to Peter and the apostles. Sinful divisions obscure and wound this gift but do not multiply the Church of Christ into several equally complete subsistences.[1]

Dominus Iesus requires Catholics to profess the historical continuity of the Church founded by Christ and rejects a model in which no concrete Church now possesses that identity. The 2007 Responses explains that Subsistit in can be predicated only of the Catholic Church because it refers to the one subject whose constitutive elements perdure together.[2]

Not an invisible aggregate

The One and Unique Church is both spiritual and visible. She cannot be reduced to all sincere Christians known only to God, a future union to be negotiated, or the sum of denominations. Those theories detach grace from the apostolic confession, Sacraments, and Hierarchical Communion through which Christ continues to act historically.

Not a denial of ecclesial gifts elsewhere

Unicity does not create a Churchless Void outside Catholic boundaries. The Church of Christ is present and operative through Elements of Sanctification and Truth in separated Churches and Ecclesial Communities. These gifts are genuinely Christ's and impel toward unity; they do not constitute another complete Church alongside the Catholic Church.[3]

Particular Churches and the one subject

Many Particular Churches do not mean many Churches of Christ in competition. In each Catholic Particular Church the one, holy, catholic, and apostolic Church is present and active. Their communion is internal to their identity, so the Universal Church is neither a numerical aggregate nor an administrative superstructure.[4]

Separated Eastern Churches remain true Particular Churches because Apostolic Succession, priesthood, and Eucharist endure. Their relation to the one subject is real but wounded by separation from the successor of Peter. This judgment affirms ecclesial reality without treating division as a legitimate permanent pluralism.[5]

Classification consequences

A community born of the Reformation without valid Orders is not a Particular Church in the proper sense, although valid Baptism and other gifts make it an Ecclesial Community. A non-Trinitarian restorationist organization whose initiation is not valid Baptism stands outside Christian ecclesial communion. These categories are consequences of what Christ gave his one Church, not rankings of human worth.

Proper names remain proper names: Church of England and Church of Jesus Christ of Latter-day Saints are correctly reproduced as such. The doctrinal classification is a separate question. Capitalization cannot create Apostolic Succession, valid Eucharist, or Trinitarian Baptism, and terminological precision must never become contempt for persons.
