The Mysterious Priests refers to a book by Bishop Fulton J. Sheen that discusses the mystery and complexity of the priestly vocation, including the struggle of faith, sacrificing oneself for the sins of the world, letting go of Christ, humor in ministry, and the challenges and frustrations facing a priest. This book is not fiction, but rather a theological and spiritual exploration of the role of the priesthood from a Catholic perspective, exploring the spiritual side (closeness to God) and the human side (being a victim of the sins of the world). The role of the priest in continuing the Incarnation, Passion, and Resurrection of Christ.
