Can Europe Force the Church to Erase a Baptism? A Belgian Case Puts Religious Freedom Before the EU Court

(ZENIT News / Luxembourg, 09.09.2026).- A dispute over a single baptismal record in Belgium could soon force Europe’s highest court to address a question with consequences far beyond one former Catholic: can data-protection law require the Church to delete the historical record of a sacrament?

The case, now before the Court of Justice of the European Union in Luxembourg, has prompted European bishops to warn that the issue touches not only the right to privacy, but also the institutional freedom of religious communities to govern themselves and preserve the visible and legal expression of their beliefs.

The dispute began when a person who wished to leave the Catholic Church asked the Diocese of Ghent to remove all personal information from Church archives, including the baptismal register. The request, made on March 25, 2021, invoked the European Union’s General Data Protection Regulation and its so-called right to erasure.

The diocese refused to destroy the baptismal entry. Instead, on April 2, 2021, it added a notation stating that the person had left the Church, marking the original entry with two diagonal lines. For the diocese, this preserved an historical fact while recording the individual’s decision to sever his or her relationship with the Church.

The person was not satisfied and appealed to Belgium’s Data Protection Authority. On December 19, 2023, the authority ordered the Diocese of Ghent to erase the data, accepting that the Church had reasons for retaining baptismal records but concluding that, in this case, the individual’s interests took precedence.

The diocese appealed. In December 2024, the Brussels Court of Appeal referred five questions to the Court of Justice of the European Union, asking, among other things, how European data-protection law should be reconciled with religious freedom and whether a notation indicating that someone has left the Church can amount to the deletion of personal data.

The case, registered as C-12/25, has now become a test of the relationship between two fundamental principles of European law: personal data protection and the autonomy of religious institutions.

For the Catholic Church, the central difficulty is that a baptismal register is not simply a membership database. That distinction is at the heart of a 15-page position paper published by the Commission of the Bishops’ Conferences of the European Union in early September.

The bishops argue that baptismal registers are records of historical events and essential instruments of proof within the Church’s legal order. They do not merely indicate whether someone currently considers himself or herself an active Catholic.

A person may stop practicing the faith or formally leave the Church, but the Church cannot alter the fact that the person was baptized. Catholic doctrine holds that baptism leaves an indelible spiritual character and cannot be repeated or undone.

That conviction also has practical consequences. Baptismal records are used in numerous matters concerning the sacramental life of Catholics, including confirmation, marriage and religious profession. Deleting an entry could therefore create serious difficulties in establishing facts that remain legally relevant within the Church.

COMECE warns that forcing the Church to erase such records would amount to more than regulating the management of a database. It could oblige a religious community to change the way it understands and records one of its central sacraments.

“Requiring the Catholic Church to delete the data contained in baptismal registers,” the European bishops argue, would constitute a serious interference with the Church’s autonomy and institutional religious freedom.

The bishops also reject the suggestion that baptismal registers should be treated as lists of current members. During a hearing before the European court on June 30, questions arose over whether the Ghent notation describing a person as having left the Church might imply that baptismal records function as membership lists.

COMECE insists that such a conclusion would be mistaken. The purpose of the register, it says, is to document the administration of a sacrament, not to measure a person’s current religious commitment.

The distinction matters because accepting the opposite interpretation could produce a misleading understanding of baptism itself. The Church fears that erasing baptismal entries could suggest that the sacrament is optional, repeatable or reversible according to later changes in personal conviction.

There is another complication: baptismal records do not concern only the baptized person. They can also contain information about parents, godparents and the minister who administered the sacrament. COMECE argues that each of these people may have an independent and legally protected interest in preserving the integrity of the historical record.

The consequences may also extend beyond Church administration. The bishops point to situations in which baptismal records have served as evidence in civil matters. In Ireland, for example, baptismal certificates can be accepted as proof of birth when civil records have been destroyed. In Cyprus, such records have been used in family disputes involving property.

Their preservation can also be important in matrimonial proceedings. COMECE cites cases in which the absence of a baptismal record could destroy evidence relevant to determining a person’s rights in Church proceedings concerning marriage.

The European bishops acknowledge that the specific notation used by the Diocese of Ghent was “not ideal” and was not representative of the practices followed elsewhere in the European Union. But they insist that the shortcomings of one particular formula should not lead courts to redefine the nature of baptismal registers altogether.

The broader legal landscape has not always been uniform. National authorities and courts in Europe have reached different conclusions on the preservation of religious records, making the Luxembourg case potentially significant for dioceses throughout the European Union.

The Advocate General is expected to issue a formal opinion on October 1, 2026. Although that opinion will not be binding, it could influence the court’s eventual judgment, expected toward the end of 2026 or in 2027.

For COMECE, the question ultimately reaches beyond the technical language of data protection.

The case asks how far a secular legal system can go in requiring a religious community to alter the records through which it preserves and expresses its own understanding of faith.

No one disputes that individuals are free to abandon the Catholic Church or reject its beliefs. That freedom is itself an essential aspect of religious liberty. But the freedom to leave a religious community raises a separate question from whether that community can be compelled to erase the historical evidence that a sacramental act took place.

That is the boundary the Court of Justice of the European Union will now have to define.

Its ruling could determine not only what happens to one baptismal entry in Ghent, but also how Europe balances the protection of personal data with the right of churches and other religious communities to preserve their history, govern their internal life and remain faithful to the beliefs on which their institutions are built.
