At the heart of priestly formation lies the deep and lifelong task of becoming a disciple configured to Christ, the Good Shepherd. In a rapidly changing world marked by complexity, uncertainty, and fragmentation, the Church is called to form future priests who are spiritually rooted, humanly mature, pastorally sensitive, and mission-oriented. Spiritual Formation: A Comprehensive Guide offers an in-depth, scholarly exploration specifically tailored to the contemporary Indian Catholic seminary context. Bringing together collective wisdom from theologians, psychologists, and formators, this volume examines effective ways to enrich and enhance spiritual growth. It navigates the journey of formation across foundational perspectives: scriptural and magisterial, classical and contextual, human and contemporary, and mission and movements. Serving as an indispensable resource for formators, spiritual directors, and seminarians, this text provides operative models to guide future shepherds as they learn to surrender their lives to the Lord freely, fondly, and blissfully.
