HAYNEUFVE, JULIEN. - Jesuit, writer on ascetical theology, one of the most distinguished masters of spiritual life in the 17th century, born at Laval on 3 September 1588, died in Paris on 31 January 1663. For 40 years he was master of novices and instructor of the Fathers in the third year of probation. A diligent student of the Holy Fathers, but especially of St. Augustine, and an eminent theologian, he drew from these sources the doctrine disseminated in his writings, which earned him the reputation of being thoroughly versed in the most intimate secrets of ascetical theology and spiritual direction. While remaining faithful to the principles expounded by St. Ignatius in the *Exercises*, he nevertheless strongly emphasized interior life and the divine life in the soul through grace.
His principal works, which had various translations and editions, are: *L'ordre de la vie et des moeurs qui conduit l'homme à son salut et le rend parfait dans son état* (Paris 1639); *Méditations sur la vie de Jésus-Christ pour tous les jours de l'année et pour les fêtes des saints* (4 vols., ibid. 1611-1642); *Méditations pour le temps des exercices* (ibid. 1643). Of the last two works he himself prepared abridgments to make them more accessible: *Abrégé des méditations pour le temps des exercices* (ibid. 1655) and *Abrégé des méditations sur la vie de Jésus-Christ* (ibid. 1655), both of which had numerous editions. Other works include: *Le grand chemin qui perd le monde. Comme on y entre. Comme on en sort* (ibid. 1646); and the work that may be called his most personal and profound: *Réponses aux demandes de la vie spirituelle par les trois voies qu'on appelle purgative, illuminative et unitive* (2 vols., ibid. 1663-65, the second posthumous, edited by Fr. L. Le Roy).
