Didier Berthet was born on 11 June 1962 and departed this world on 8 September 2023. An eminent French Roman Catholic prelate, he dedicated a significant portion of his life to serving the church and held the esteemed position of bishop of Saint-Dié from June 2016 till his untimely demise.


Conversion and Training

Born in Boulogne-Billancourt, Hauts-de-Seine, Berthet’s spiritual journey is a testament to the idea that faith can evolve over time. With a Roman Catholic father and a Calvinist Protestant mother, he was initially baptized in the Reformed Church of France and underwent a Calvinist education. His teen years were spent at the Saint Jean Hulst Catholic College in Versailles between 1975 to 1980.

Despite aspiring to become a pastor upon completing high school, Berthet’s spiritual perceptions began to shift. This shift solidified in 1980 when he experienced a transformative event: a meeting with young followers during Pope John Paul II‘s visit to France. This encounter made him appreciate the depth of the Catholic Church’s legacy and its apostolic nature. By 1983, while a student at the Institute of Political Studies in Paris, Berthet embraced Catholicism. His theological studies subsequently took him to the French seminary of Rome and the Gregorian University of Rome between 1987 and 1993, culminating in a Bachelor’s Degree in Theology and Canon Law.
