Having completed the usual course of study at the University of Pont-à-Mousson, he taught at the Jesuit colleges in La Flèche, Bourges and Rouen.
He was ordained and taught philosophy for some time until in 1622 he was made master of novices, an office he filled for four years.
In 1628 he was appointed director of tertians, and as such, was responsible for the final year of formation for close to sixty Jesuits between 1628 and 1631.
After three years in this post he broke down in health, and was sent to the college of Bourges, in the hope that change of occupation would restore him.
[2] He is known today chiefly by his “Doctrine Spirituelle”, a collection of his maxims and instructions gathered together by Father Jean Rigoleuc, one of his disciples, and detailing very thoroughly his spiritual method.
