"Protestantism, whether primitive or modern, Lutheran or Calvinist, orthodox or liberal, generally occurs as a religion of antitheses—and liberal theology is not the least marked by this characteristic. Either rites or morals, authority or liberty, faith or works, nature or grace, prayer or sacrifice, Bible or pope, Christ the Saviour or Christ the judge, sacraments or the religion of the spirit, mysticism or prophecy … but Catholicism does not accept these dichotomies and refuses to be merely Protestantism turned inside out."
