Can Europe Erase a Baptism? A Legal Battle Puts Church Autonomy to the Test
A Belgian Catholic’s request to erase his personal details from a baptismal register has become a broader European debate over data privacy and Church autonomy. The case, known as Bisdom Gent, is before the Court of Justice of the European Union after Advocate General Laila Medina issued an opinion on October 1. Medina said data-protection law may allow removal of personal information if the Church cannot show compelling legitimate grounds to retain it; her opinion is not binding.

A case before the Court of Justice of the European Union asks whether a person can use European data-protection law to have identifying details removed from a baptismal register, and how that right should be balanced against a church’s autonomy and interest in preserving its records. The court has not yet ruled: an Advocate General’s nonbinding opinion proposes case-by-case assessments, with a final judgment expected in late 2026 or 2027.
In March 2021, a baptized Belgian citizen asked the Diocese of Ghent to erase his personal information from its records, including its baptismal register, under the EU’s General Data Protection Regulation. The diocese left the entry in place but added a notation that he had left the Church and marked the original entry with two diagonal lines.
The complainant rejected that response, and Belgium’s data-protection authority ordered the diocese in December 2023 to comply. The diocese appealed; in December 2024, the Brussels Court of Appeal referred five questions to the EU court, including how data-protection rules relate to religious freedom and whether recording a person’s departure from the Church can count as erasure.
Advocate General Laila Medina’s October 1 opinion says data-protection law can, in principle, entitle a baptized person to have identifying information removed if a church cannot show compelling legitimate grounds for keeping it. The opinion does not propose an automatic right to delete baptismal records; it calls for national courts to weigh the individual’s privacy, data-protection and religious-freedom rights against the church’s autonomy and freedom of religion in each case.
If deletion is warranted, the opinion says that crossing out an entry may not suffice: the person’s information would need to become illegible so they could no longer be identified, or easily identified. The record could still retain the fact that a baptism occurred at a particular place and time.
The Commission of the Bishops’ Conferences of the European Union (COMECE) argues that removing a person’s name and surname could deprive a baptismal entry of much of its meaning. Its general secretary, Father Manuel Barrios, says baptismal registers document that a sacrament took place at a specific time and under particular circumstances, rather than serving as lists of people who currently identify as Catholic.
In Catholic teaching, baptism leaves an indelible spiritual character and cannot be repeated, even if someone later stops practicing or formally rejects the faith. COMECE says registers can also contain information about parents, godparents and the minister, and can help verify baptism for later matters such as marriage, religious vows or ordination.
Barrios has presented the Belgian dioceses’ notation—recording that a person has left the Church while retaining the baptismal entry—as a possible compromise between individual autonomy and preservation of the community’s sacramental history. He has also cited cases in which a baptismal record could help establish a seriously ill person’s sacramental history.
COMECE says the opinion recognizes church autonomy, religious freedom and the proper administration of the sacraments, but it warns that a deletion requirement could create uncertainty for churches handling data across the EU’s 27 member states. It also says the ruling could raise questions in some countries about the relationship between EU obligations, concordats and national laws that recognize aspects of canon law.
Several European countries and institutions argued against a general right of deletion during the proceedings; Czechia, Austria, Italy and Latvia emphasized collective religious freedom and the autonomy of religious communities. The case also concerns Article 17 of the Treaty on the Functioning of the European Union, which requires the EU to respect the status of churches and religious associations under national law and to maintain an open, transparent dialogue with them.
Sacramental permanence grounds Church autonomy amid personal-data claims
The Catholic rationale for retaining a baptismal entry is that it records a sacramental event and a person’s canonical history—not merely a current religious preference. Baptism confers a permanent sacramental bond that is not undone by later departure from the Church.
Canon law accordingly requires parishes to keep baptismal registers accurately and carefully, record specified later changes in canonical status, and protect the registers from outsiders. Church practice can therefore distinguish between deleting the historical record and annotating it: the Church’s own guidance, for example, provides for a formal departure to be noted in the register.
That theological and canonical case supports the Church’s claim to manage records needed to document its sacramental life. But it does not, by itself, resolve every civil-law question about personal data, data minimization, or the limits of religious autonomy. The materials available here do not establish how the Belgian court should balance those legal claims or what decision it reached.
