Ordained priest in 1878, he taught dogmatic and moral theology at Rodez, Baltimore and at Saint-Sulpice in Paris. Superior of the novitiate (1915–26) at Issy-le-Moulineaux, he devoted himself to studies in ascetical theology. His publications continue to enjoy considerable popularity, in which, alongside solid doctrine and rich documentation, the author’s concern to be practical, up-to-date and responsive to modern needs is clearly evident.
He wrote: *Synopsis theologiae dogmaticae* (3 vols., Paris-Rome 1894–96; 25th ed. ibid. 1942); *Synopsis theologiae moralis et pastoralis* (3 vols., ibid. 1902); *Breviary synopsis theologiae dogmaticae* (ibid. 1911); *Breviary synopsis theologiae moralis et pastoralis* (ibid. 1913); *Præcis de theologia ascetica et mystica* (ibid. 1923), a work translated into ten languages in a short time; *Dogmes générateurs de la piété* (Paris 1926); *La divinisation de la souffrance* (ibid. 1931); *Jésus vivant dans l'Église* (ibid. 1932). He contributed extensively to Catholic dictionaries and reviews such as the *Dictionnaire de Théologie Catholique*, the *Catholic Encyclopedia*, the *American Ecclesiastical Review* and *La Vie spirituelle*.
