Fr. Dujarié was one of the first to consider a society of priests to support the brothers and sisters. Religious groups after the Revolution were not legally recognized, so they could not own property, accept gifts and endowments and administer their finances. So, in Fr. Dujarié's view, the priests would serve this purpose. But nothing was done to implement his idea.
Fr. Moreau, however, had a different idea as you can see.
On June 19, 1835, Fr. Moreau wrote to Bishop Bouvier as follows: "Am I to found a house of diocesan missionaries, which can a the same time serve as a house of retirement for infirm or retired priests, as well as for retreats for the laity at certain times of the year?" In the margin Bishop Bouvier wrote, Yes. This was the approval Fr. Moreau needed and so just before accepting the Brothers of St. Joseph, he was on retreat with two priests and two seminarians in the Trappist Monastery of Notre Dame Port-du-Salut seen in the photo below.
Here Fr. Moreau, Abbés Cottereau and Nourry, and two seminarians Abbés Veron and Moriceau decided on the spiritual life they were to lead. They adopted the name "Auxiliary Priests" indicating that besides the preaching of retreats and missions they would also engaged in parochial ministry when needed.
Since Fr. Moreau was still assistant superior at St. Vincent's Seminary, they would temporarily reside there. In 1836 they began preaching in different parishes. In all these parishes they enlivened the faith of the people by erecting the Way of the Cross. They found this devotion most helpful in engendering the human heart faith, contrition and hope.
