Newman is a magnificent guide for all those who perceive that the key, the focal point and the goal of all human history is to be found in Christ. -St. John Paul II Carefully composed over twenty years, Newman's Essay in Aid of a Grammar of Assent is an ackwledged masterpiece both for its apologetic response to atheistic naturalism and its positive contribution to the Catholic theology of faith. Newman confronts the dilemma of modern skepticism through a sustained investigation of what it means for the mind to give assent. He shows how the believer, who encounters the light of Christ, can give a certain assent to the propositions of the faith even in the absence of demonstrative proof. Blessed John Henry Cardinal Newman was England's greatest Catholic convert and theologian of the nineteenth century. Newman's many written contributions to Catholic theology and culture include An Essay on the Development of Christian Doctrine, The Idea of a University, and Apologia pro Vita Sua. He was beatified by Pope Benedict XVI in 2010.
