Few Catholic thinkers have left as deep and permanent a mark on the intellectual, cultural, and pastoral life of the church as John Cardinal Newman. His writings on faith, An Essay in Aid of a Grammar of Assent, and his own conversion, Apologia pro Vita Sua, as well as his countless letters on papal infallibility and the sanctity of Mary remain profoundly influential for our times. World-renowned Newman scholar Roderick Strange sheds new light in Newman 101 on the controversies and achievements that defined the life and brilliance of this great mind.
