Fr Toussaint Dassy was recovering from a serious illness at Notre Dame de l’Osier and as his strength was restored he became increasingly more involved in the pastoral demands of the area. So successful was he that he was able to persuade the Bishop to give the administration of the shrine and parish to the Oblates.
Eugene worried about this young talented and enthusiastic priest losing focus and burning out. He reminds him to be faithful to the Rule as his compass:
In the meantime I’m relying on you not to lose the spirit of your Rule. Make your manner of observing it the matter of your daily examen, otherwise you are going to feel the strain of your isolation, and the ministry that you are now doing out of zeal is going to become your means of escape.
Don’t take on too much work, you understand you cannot accept every offer, there must be moderation in everything.
Letter to Fr. Toussaint Dassy, 25 April 1834, EO VIII n 479
