This is the story of an intellectucal and spiritual pilgrimage from reformed Judaism to the priesthood in the Roman Catholic Church. It is the narrative of a personal experience with the intellectual element always paramount. The author describes the faith in which he was brought up, and the failure of his experience in school and college to satisfy his intellectual and spiritual hunger. Through student friends, also Jews, who were interested in philosophy young Simon became involved in a study of the Catholic thinkers who progressively intrigued him until finally he came to the decision to embrace the Catholic faith. The story of as radical change of faith as this is always interesting, but it is primarily the intellectually mature and the spiritually impoverished who will follow this account with intelligent and sympathetic interest.
