Abstract
This essay examines Newman’s life-long campaign against the errors of liberal religion, particularly its “anti-holiness” principle that rejects the Christian commitment to the pursuit of sanctity. In both his Anglican and Roman Catholic writings, Newman attacked the “anti-holiness” principle’s underlying presuppositions, particularly (1) its naturalistic anthropology, (2) its “anthropocentric horizon of discourse,” (3) its rejection of ascetic discipline in religious formation, and (4) its tendency to accept uncritically what is intellectually novel.
