In 1801, an agreement between Napoleon and the Vatican restored public worship and reconstituted the Catholic Church in relationship with the state. The Church now faced the daunting task of rebuilding. In 1803, Dujarié was appointed pastor of the parish in Ruillé-sur-Loir, where he worked zealously to tend to the many needs of his flock.
When the Diocese of Le Mans clergy asked Fr. Dujarié to assemble a group of teaching brothers to serve in parishes, he founded the Brothers of St. Joseph (1820). As the brothers grew in number, Fr. Dujarié realized the group was tenuous. So he assembled a group of diocesan priests to work with them and give cohesion to the structure. In 1835, Fr. Dujarié was in failing health. With the bishop's consent, he selected Rev. Basile Moreau to continue his work.
The rest is history.
Moreau moved the brothers to Sainte-Croix, a neighborhood of Le Mans. Two years later, in the Fundamental Act of Union, the Brothers of St. Joseph were formally united with Fr. Moreau's group of auxiliary priests, thus creating the Congregation of Holy Cross.
