Stanislas Lalanne

Stanislas Marie Georges Jude Lalanne was born in Metz, in the Moselle, on 3 August 1948. His father, Albert Lalanne, was an officer in the army engineers, and his mother was Odile Martin-Saur.

He entered the major seminary of Versailles and continued his formation at the Carmes seminary in Paris, taking courses at the Institut Catholique de Paris and at Paris-Sorbonne University, as well as at the University of Tubingen in Germany. He earned a master's degree and the qualification to proceed to a doctorate in theology, together with a degree in German. Much later, in 1992 and 1993, he attended the national defence studies course of the Institut des hautes etudes de defense nationale.

Lalanne was ordained a priest for the diocese of Versailles on 8 November 1975. From 1975 to 1980 he was chaplain to the secondary schools of Versailles, and until 1985 he led the diocesan service for chaplaincies in state schools and was chaplain to the students of Versailles. He then took this work to national level as secretary of the bishops' commission on Catholic education and director of the Centre national de l'enseignement religieux until 1993, directing the writing of several catechetical books.

Back in his home diocese he was parish priest of Sainte-Pauline at Le Vesinet and then of Elancourt-Maurepas until 1999. In 1997 he directed the press centre for World Youth Day in Paris, and he became episcopal vicar for communications in the diocese of Versailles. From 1999 to 2001 he was deputy secretary general and spokesman of the Bishops' Conference of France, and from 2001 to 2007 its secretary general, years in which he became a familiar figure on French radio and television.

On 4 April 2007 Pope Benedict XVI appointed him the ninth Bishop of Coutances and Avranches, succeeding Jacques Fihey. He was consecrated in Notre-Dame cathedral in Coutances on 3 June 2007 by Cardinal Jean-Pierre Ricard, then president of the bishops' conference. In 2008 he was elected to the conference's studies and projects committee and re-elected in 2011, and he also sat on its finance commission.

On 31 January 2013 he was appointed Bishop of Pontoise, a role that made him guardian of the Holy Tunic kept at Argenteuil. He led the diocese for eleven years. At the Roman Curia he was a consultor of the Pontifical Council for Social Communications, and on 13 July 2016 Pope Francis named him a member of the newly created Secretariat for Communication. In June 2022 the pope sent him to carry out an apostolic visitation of the archdiocese of Strasbourg, and on 7 November 2023 he was appointed apostolic commissioner of the Oratory of France after complaints about the congregation reached Rome.

In April 2016 he drew strong criticism after saying in a radio interview on RCF that he was not sure paedophilia could properly be called a sin. He returned to the station days later to say that he had not meant to trivialise abuse, that paedophilia was an objectively grave sin, and that his point concerned the degree of responsibility of the person who commits such acts.

His resignation on reaching the age limit was accepted on 4 June 2024, and Benoit Bertrand, until then Bishop of Mende, succeeded him in Pontoise.

Lalanne was a Catholic priest and bishop and did not marry. He was made a knight of the Legion of Honour on 14 July 2005.

He co-wrote, with Bishop Michel Dubost, Le nouveau Theo, an encyclopaedia of the Catholic faith for general readers published in 2009. He also published Un eveque se confie (Bayard, 2017), a book of reflections on his ministry, and Vivre et esperer (Salvator, 2020). He argued for what he called a catechesis of current events, meeting young people through real moments in their lives such as World Youth Day.

Stanislas Lalanne died suddenly in Versailles during the night of 16 to 17 August 2026, at the age of 78. His death was announced on 17 August by his successor, Bishop Benoit Bertrand of Pontoise, who wrote of his deep sadness and called it a shock for everyone, beginning with his family. The cause of death was not made public.

The Bishops' Conference of France and the diocese of Versailles, where he had been ordained, joined in the tributes, and the prefecture of the Val-d'Oise praised him as a man of conviction and dialogue who had built relations between the diocese and the state on mutual respect and trust.

His coffin lay in Saint-Maclou cathedral in Pontoise on 25 August for a day of prayer, followed by an evening vigil. His funeral took place on 26 August 2026 at the church of Blessed Frederic Ozanam in Cergy, presided over by Archbishop Laurent Ulrich of Paris, with extra places and large screens set up outside for the congregation. He was buried that evening in the bishops' vault of Saint-Maclou cathedral.

Lalanne is remembered in the French Church above all as a communicator. As spokesman and secretary general of the bishops' conference he helped give the French episcopate a clearer public voice, and he carried that interest into his work for the Vatican's communications bodies. In Pontoise his successor recalled his passion for proclaiming the Gospel, his joy in celebrating the sacraments and his drive to communicate. The trust placed in him by Pope Francis, who gave him delicate assignments in Strasbourg and at the Oratory of France in his final years in office, reflected his standing as an experienced and steady pair of hands.
