During the first years after the Sisters had made their Profession, the development of the community was very slow. From 1828 to 1837 only five religious joined the Foundresses, (…). With no hope of the situation getting better, they conceived the idea of joining another congregation. In the meantime, Father Deshayes, Superior General of the Sisters of Wisdom and Fathers of the Company of Mary, came to Rochefort-en-Terre. Father Corvoisier, his friend, and almost his fellow-countryman as they came from neighbouring parishes, went to see him to put the case to him. Instead of addressing the problem immediately, Father DESHAYES said he wished to study the question on the spot. A few days later he arrived at the Presbytery in Saint-Jacut with two of his missionaries. After praying for a long time before the Blessed Sacrament, together with the parish priest he went to the community and questioned each Sister separately. This interview gave him the opportunity of recognizing the profound humility and the admirable charity that reigned among them. So, without further hesitation he said to them, “My dear Sisters, your work is the work of God. Do not join another congregation, stay as you are.” This pronouncement decided the lot of the young community. They remained as they were.
The time had come for the Sisters to have a fixed rule, and to achieve this, Father Corvoisier did not hesitate to appeal to the experience of Father Deshayes. The latter had just founded, at Saint GiIdas des Bois, a congregation whose aim was exactly the same as the community of Saint-Jacut. Father Deshayes consented willingly to what was asked of him and provided the parish priest with very useful information. All the same, the rule was chiefly the work of two Jesuit priests who often came to Saint-Jacut to give the annual retreat. The two Jesuits were Father Leleu, who died at Vannes in the odour of sanctity, and Father Lestrohan. The Sisters tried out the Rule under their direction and it was followed by the Institute up to 1912.
