February 1944; Le Drame de l'humanisme athée, published in December 1944; De la connaissance de Dieu published in 1945; Surnaturel: Études historiques (a book which de Lubac had started at Hastings in his student days), published in 1946 in a print run of 700 copies, because of the ongoing paper shortage. "The dark years" In June 1950, as de Lubac himself said, "lightning struck Fourvière." De Lubac, who resided at Fourvière but actually did no teaching there, and four Fourvière professors were removed from their duties (in de Lubac's case these included his professorship at Lyon and his editorship of Recherches de science religieuse) and required to leave the Lyon province. All Jesuit provincials were directed to remove three of his books (Surnaturel, Corpus mysticum, and Connaissance de Dieu) and one article from their libraries and, as far as possible, from public distribution. The action came through the Jesuit Superior General, Jean-Baptiste Janssens, under pressure from the curial office, and was because of "pernicious errors on essential points of dogma." Two months later, Pope Pius XII issued the encyclical Humani generis, widely believed to have been directed at de Lubac and other theologians associated with the nouvelle théologie, an intellectual movement characterized by renewed attention to the patristic sources of Catholicism, a willingness to address the ideas and concerns of contemporary men and women, a focus on pastoral work and respect for the competencies of the laity, and a sense of the Catholic Church as existing in history and affected by it. What de Lubac called "the dark years" lasted nearly a decade. It was not until 1956 that he was allowed to return to Lyon and not until 1958 that the University got verbal approval from Rome for de Lubac to return to teaching the courses he previously taught. Although everything de Lubac wrote during these years was subject to censorship in Rome, he never ceased to study, write, and publish. During these years he brought out a study of Origen's biblical exegesis (1950), three books on Buddhism (1951, 1952, 1955), Méditations sur l'Église (1953 – a text which would have great influence on Lumen Gentium, the document produced at Vatican II on the nature of the church), and Sur les chemins de Dieu (1956). Return to acceptance His pioneering study Exégèse médiévale (1959–1965) revived interest in the spiritual exegesis of scripture and provided a major impetus to the
