Cardinal Sarto became Pope Pius X on 4 August 1903. On 1 October, Loisy published three new books, Autour d'un petit livre, Le Quatrième Évangile and Le Discours sur la Montagne (a fragment of a proposed enlarged commentary on the Synoptic Gospels). Autour consists of seven letters on different topics addressed to church Leaders and friends. On 23 December the pope ordered the publication of a decree of the Index of prohibited books, incorporating a decree of the Inquisition, condemning Loisy's Religion d'Israël, L'Évangile et l'Église, Études évangéliques, Autour d'un petit livre and Le Quatrième Évangile. On 12 January 1904 Loisy wrote to the Vatican Secretary of State, Cardinal Merry del Val, that he received the condemnation with respect, and condemned whatever might be reprehensible in his books, whilst reserving the rights of his conscience and his opinions as an Historian. Since the Holy See was not satisfied, Loisy sent three further declarations to Rome; the last, dispatched on 17 March, was addressed to the pope himself, and remained unanswered. At the end of March Loisy gave up his lectureship, as he declared, on his own initiative. In April 1907 he returned to his native Lorraine, to Ceffonds (near Montier-en-Der), and to his relatives there.
