The 28 year-old Jean Joseph-Marie Lagier had been a diocesan priest for 5 years and, meeting the Oblates at Notre Dame de l’Osier, discerned an Oblate vocation. At the end of his novitiate year he was preparing himself to make his life-time oblation. Eugene wrote about his with joy.
Speaking of Father Lagier, I can tell you that I have never seen anyone prepare himself for a holy event of oblation as he did. And in consequence what fruits won’t he derive from it? Father Lagier can’t contain himself for jubilation. He told us, he who has always been so fervent both at the seminary and in the parish, that he has never known such peace and happiness, that he was overflowing with gladness and along with these outpourings from his noble soul he brings a firm resolution to do all for the glory of God, the service of the Church and of the Society, in whatever work obedience assigns him.
He is on fire to work for the salvation of souls, but he waits without anxiety for his superiors to choose the ministry in which they wish to employ him. To sum it all up in a few words, a more perfect subject couldn’t be found.
Letter to Henri Tempier, 16 August 1835, EO VIII n 533
Jean Lagier was to continue living in this spirit for the rest of his life, and sharing it with others mostly as a formator, professor and seminary rector. (See https://www.omiworld.org/lemma/lagier-jean-joseph-marie/ )
