First published in 1950 Roman Catholicism is an attempt on the part of a Roman Catholic to state what he conceives to be the nature and function of the Church to which he belongs. Those who read the book are asked to believe that what it contains is set down in all sincerity and honesty. The book brings themes like function and unity of the Roman Catholic Church; Roman Catholic theology; moral and social teaching; Roman Catholicism and human history; link between Roman Catholicism and modern situation; and Catholic life and practice. This book is essential for scholars and researchers of Christianity, Catholicism, and religion in general.

In this unique handbook of Christian literature, the founder of the Jesuits offers a way of "raising the mind and heart to God." Saint Ignatius of Loyola avoids setting a formula for prayer, providing readers with an extensive variety of meditative themes. Although originally intended for those making a retreat under the direction of an experienced master, the spiritual exercises have since become much more widely known and used, and they offer an excellent resource for private devotions.
