The success of the Oblate mission depended in a large measure to the goodwill of the local bishop. Eugene reminds Fr. Guigues and his community of the importance of this at ND de l’Osier.
You cannot be too grateful to the Bishop of Grenoble for his immeasurable goodwill towards you. Always maintain trusting relations with him such as a good man like that is capable of appreciating, and take pains to give him proof that there are no priests in his diocese more devoted to him than ourselves. It is not enough that you are such, see to it somehow that he knows it. You owe him that consolation.
Letter to Bruno Guigues, 10 October 1834, EO VIII n 490
Writing to Fr Aubert, Eugene boasts how successful the Osier community had been in cultivating a good relationship with the Bishop of Grenoble.
Guigue[s] has written me the most consoling things about how his community is getting on with the Bishop of Grenoble, who praised him and his confreres to the skies in the presence of all the clergy gathered for the retreat.
He even gave the latter a free hand to enter the noviate if they wanted to. It is really marvellous!
Letter to Casimir Aubert, 11 October 1834, EO VIII n 491
