Loisy next became chaplain to a Dominican convent and girls' school at Neuilly-sur-Seine (Oct. 1894-Oct. 1899), and here matured his apologetic method, resuming in 1898 the publication of longer articles, under the pseudonyms of Desprès and Firmin in the _Revue du clergé français_, and of Jacques Simon in the lay _Revue d'histoire et de littérature religieuses_. In the former review, a striking paper upon development of doctrine (Dec. 1st, 1898) headed a series of studies apparently taken from an already extant large apologetic work. In October 1899 he resigned his chaplaincy for reasons of health, and settled at Bellevue, somewhat farther away from Paris. His notable paper, "La Religion d'Israël" (_Revue du clergé français_, Oct. 15th, 1900), the first of a series intended to correct and replace Renan's presentation of that great subject, was promptly censured by Cardinal Richard, archbishop of Paris; and though scholarly and zealous ecclesiastics, such as the Jesuit Père Durand and Monseigneur Mignot, archbishop of Albi, defended the general method and several conclusions of the article, the aged cardinal never rested henceforward till he had secured a papal condemnation also. At the end of 1900 Loisy secured a government lectureship at the École des Hautes Études Pratiques, and delivered there in succession courses on the Babylonian myths and the first chapters of Genesis; the Gospel parables; the narrative of the ministry in the synoptic Gospels; and the Passion narratives in the same. The first course was published in the _Revue d'histoire et de littérature religieuses_; and here also appeared instalments of his commentary on St John's Gospel, his critically important _Notes sur la Genèse_, and a _Chronique biblique_ unmatched in its mastery of its numberless subjects and its fearless yet delicate penetration.
