Under Tharin's successor, Bishop Johann Franz Lepape von Trevern, he withdrew more from public life. His last years were spent in retirement in the mother-house of the Sisters of Charity. Works His "Institutiones theologicæ" were first published in five volumes (Mainz, 1819–27; 6th ed., 1844) and later in two (10th ed., Mainz, 1870). This work was used as a textbook for years in many theological seminaries in Germany, France, Belgium, and America. During the time of the Revolution, Liebermann published several anonymous pamphlets in defence of the rights of the Church and against the required oath of the civil constitution of the clergy. Of his sermons several have been published separately, e.g. "Lob- und Trauerrede bei Gelegenheit des Hintrittes des hochwürdigsten Herrn Joseph Ludwig Colmar, Bischof zu Mainz" (Mainz, 1818). After his death appeared:- "Liebermann's Predigten, herausgegeben von Freunden und Verehrern des Verewigten" (3 vols., Mainz, 1851–3). From 1825 to 1826 he was editor of the "Der Katholik".
