Priesthood is a sacred and profound calling, requiring a life of dedication, personal holiness, and self-sacrifice. From the moment of ordination, the priest enters a unique and transformative relationship with Christ, the Good Shepherd, who laid down His life for His sheep (John 10:11). This book, Heart of the Shepherd: Character and Life of the New Testament Priest, explores the depth of this calling, grounded in Scripture, the wisdom of the Church Fathers, and the Church's liturgical tradition. This book is written as a reflection on the sacred nature of the priesthood, offering insights into the spiritual character, responsibilities, and life of the New Testament priest. Each chapter delves into key aspects of the priest's role, starting with his sacred calling and character formation, progressing through the centrality of teaching, preaching, and the Eucharist, and concluding with the legacy a priest leaves in his community. In every aspect of his ministry, the priest reflects God's fatherly love, guiding the faithful with compassion, patience, and wisdom.
