For a while he held the title of Auxiliary Bishop of Paris, where, among others, he served in the Notre-Dame Cathedral too. Furthermore, he worked as the Chaplain of the Eucharistic Youth Movement. He also served as rector of the Paris Seminary. In 2018, He was appointed Archbishop of Bourges by Pope Francis.
