Reform of the Monasteries
Gauzelin made the renewal of monastic life a central concern of his episcopate. According to the sources he traveled to Fleury-sur-Loire (Saint-Benoît-sur-Loire) to study its Benedictine observance, and worked to introduce that discipline in his own diocese, gradually replacing the older Columban usages. He personally established the observance of Fleury at the abbey of Saint-Epvre (St. Aper).
He also supported the broader reform movement of the region: the archdeacon of Toul, Einold, initiated the reform of the abbey of Gorze, which Gauzelin encouraged. An Orthodox account further relates that he recruited the scholar Adso of Luxeuil to establish a school at the abbey of Saint-Epvre. Throughout, he sought to maintain and develop the property and patrimony of his church.
