[1] Some sources attribute a turbulent youth to him, which did not prevent him from being destined for a career in the Church; he was provided with the Abbey of St. Hydulphe at Moyenmoutier on 31 March 1588.
In 1604 the resulting new constitution of the Congregation of St. Vanne and St. Hydulphe received Pope Clement VII's approval.
He returned to Verdun in 1597 and, encouraged by Cardinal Bellarmine, showed himself a model bishop: he organized synods and played an important part in the reform of the Benedictine orders in Lorraine.
He fell in love with and married a woman called Marie Dupuy (died 1640[3]).
In 1610, he renounced his office as bishop of Verdun in favor of his nephew Charles,[4] and retreated to the Capuchins.
