Modern Substitutes for Christianity is a work by Pearson McAdam Muir (1846-1924), the Scottish minister of Glasgow Cathedral and Moderator of the General Assembly of the Church of Scotland. Muir surveys and answers the philosophies and movements that the late nineteenth century offered in place of orthodox Christian faith.
