Reception into the Corresponding Church sui iuris is the Eastern canonical rule that a baptized non-Catholic entering Full Communion retains the person's proper rite and is ascribed to the Catholic Church sui iuris of that rite rather than automatically becoming Latin Catholic.
Communion without ritual absorption
CCEO canon 35 requires baptized non-Catholics who come into Full Communion to retain, cherish, and observe their own rite everywhere and therefore to be ascribed to the Church sui iuris of the same rite. The norm ordinarily places an Orthodox, Oriental Orthodox, or Assyrian Christian in the corresponding Eastern Catholic Church, not in the Latin Church merely because a Latin parish receives the profession.[1]
Reception heals ecclesial communion; it does not declare the person's inherited liturgical, spiritual, theological, and disciplinary patrimony defective or disposable. Orientalium Ecclesiarum commands preservation of Eastern rites as the heritage of the whole Church and rejects unnecessary burdens in the reception of separated Eastern Christians.[2]
Corresponding does not mean identical
The corresponding Catholic Church shares the relevant ritual and ecclesial patrimony but is not juridically identical to the non-Catholic Church from which the person comes. Historical borders and present structures may not align neatly, so competent Catholic authority must establish the correct ascription rather than relying on a parish's guess.
The Holy See can address special cases
Canon 35 preserves the right of recourse to the Apostolic See in special cases affecting persons, communities, or regions. That reservation protects difficult histories without converting personal preference into a general right to evade the corresponding Church.
Minister of reception and canonical ascription
A Latin priest can in lawful circumstances receive an Eastern Christian into Catholic communion, but the minister's own ascription does not decide the recipient's. Canonical records should state the profession, reception, prior Baptism and Chrismation, and the Church sui iuris to which the person is ascribed.
The rule also prevents a silent change produced by years of attendance at a Latin parish. Catholics may receive the sacraments in another Catholic rite according to law, yet worship location is not itself Transfer Between Churches sui iuris. A later lawful transfer requires the competent process and record.
Pastoral duties after reception
If the corresponding Church has no nearby parish or hierarch, the person remains entitled to Catholic pastoral care without losing Eastern identity. Eastern Catholic Faithful without Their Own Hierarch can be entrusted to a Latin or other Eastern ordinary while retaining ascription and the right and duty to preserve their proper rite.[3][4]
Rite, Church sui iuris, Particular Church, parish, and minister are distinct. Phrases such as converted to the Roman rite or became Roman Catholic are inaccurate when the canonical act was reception into an Eastern Catholic Church in Full Communion with Rome.
