“At last I have found my vocation. My vocation is love!” Love is truly the heart of every vocation. This book available for the first time here looks at the Catholic understanding of the vocation to marriage, priesthood, or religious life. It has several features are nearly unique among books on vocation. First, while being addressed to all Catholics, not only to theologians, it does not oversimplify vocation, or give a mere compilation of advice, but aims to present the rich depth and wealth of the Catholic understanding of vocation in a simple and accessible manner. Secondly, this book goes right to two great saints at the heart of quite different traditions on vocation, namely St. Thomas Aquinas and St. Ignatius Loyola, and the basic difference between them, a difference which is often unappreciated, or is passed over superficially. The goal is not to decide in favor of one over the other, nor to examine in detail their historical or theological connection; this book rather aims to use these different points of view to convey all that belongs to a full Christian and human approach to vocation.
