It must indeed have been a time of great satisfaction for Father de Mazenod. On November 1, 1818, after receiving the necessary authorization from Guigou, he pronounced his vows of chastity, obedience and perseverance in the presence of Fortuné; during the Mass which followed, he accepted the vows of Fathers Maunier, Mie, Tempier and Moreau and of the scholastic brothers Dupuy, Courtès and Suzanne.

The formula used by Eugene was:
In the name of Our Lord Jesus Christ, in the presence of the Most Holy Trinity, the Blessed Virgin Mary, all the Angels and all the Saints, all my brothers here assembled, I, Charles Joseph Eugene de Mazenod, profess, promise to God and vow perpetual chastity and obedience; I swear and likewise vow to persevere until death in the holy institute and society of the Missionaries known as Missionaries of Provence. So help me God.
