From an orthodox Protestant he gradually became a bitter enemy of Christianity, which he attacked in a number of writings and for which he strove to substitute a new religion "of love and peace", formulated in his work Religion des neuen Weltalters. Karl Marx and Frederick Engels joined in writing a critical review of Daumer's Die Religion des Neuen Weltalters in January through February 1850 which was published in the Neue Rheinische Zeitung: Politisch-Ökonomische Revue.
