An adviser to the European Union's top court has indicated that European data protection law may require churches to erase baptismal records when a baptized person asks for their removal, according to a report by EWTN Great Britain.

The opinion came from an Advocate General of the Court of Justice of the European Union (CJEU), the Luxembourg-based tribunal that serves as the final interpreter of EU law. The case centers on a question with few precedents: whether entries in parish baptismal registers — documents that churches have maintained for centuries as canonical records of sacraments administered — fall within the reach of the General Data Protection Regulation (GDPR), and if so, whether individuals can invoke the right to erasure against them.

What the adviser said

According to the report, the Advocate General took the view that European data protection rules do not categorically exempt ecclesiastical records. A baptismal entry, the opinion suggests, constitutes personal data relating to an identifiable individual: it records a name, a date, and a sacramental act. If that data is processed in a form that permits identification, the logic of the GDPR can apply.

The adviser further indicated that the regulation's right to erasure — often called the "right to be forgotten" — may extend to such records, allowing a person who no longer identifies with the faith to seek the deletion of their baptismal entry.

The opinion stops short of resolving the question definitively. Advocates General at the CJEU deliver independent legal opinions designed to assist the Court's judges. The judges are not bound by these opinions, although in practice they follow them in a substantial majority of cases. A final judgment will issue from the Court in due course.

Why the question matters

Baptismal registers occupy an unusual position in European law and church governance alike. Under canon law of the Catholic Church, a baptism — once validly administered — cannot be undone, and the parish record of it serves permanent canonical purposes: establishing sacramental status, verifying eligibility for marriage and holy orders, and documenting the reception of sacraments across a person's lifetime. Dioceses have historically preserved these registers indefinitely, and many European parishes hold volumes going back generations.

European data protection law, by contrast, treats personal data as something individuals should generally control. The GDPR grants data subjects rights of access, rectification and erasure, subject to enumerated exceptions. Several member states negotiated specific accommodations for religious bodies when the regulation was adopted, recognizing churches' constitutional position in countries such as Germany, where religious communities enjoy a measure of self-determination. How those accommodations interact with an individual's erasure request is precisely the tension the CJEU must now address.

Practical consequences for practitioners

For data protection lawyers, the opinion signals that religious record-keeping should no longer be assumed to sit outside the GDPR's perimeter. Counsel advising dioceses, diocesan data protection officers, and churches of other denominations that maintain membership or sacramental registers — including Anglican, Lutheran and Orthodox bodies — will want to audit their registers against the regulation's requirements: lawful basis for processing, retention schedules, and procedures for handling erasure requests. Where national concordats or church-state agreements guarantee ecclesiastical autonomy, practitioners may need to argue that those instruments constitute countervailing legal obligations that justify continued retention under the regulation's exceptions. Until the Court delivers its judgment, however, no final answer exists, and organizations facing deletion demands should treat the Advocate General's position as a strong indication of the likely direction of travel rather than settled law.

For individuals, the practical effect if the Court follows the opinion would be a recognized avenue to have their baptismal entries removed from parish records — a step sought by organized groups of people who have left the Church in several European countries in recent years.

The Court of Justice will now deliberate. Its judgment will bind courts and regulators across all 27 member states.
