As the Diocese of Kidapawan celebrates her 40 years of being a Diocese this year, this book is a product of forty-two (42) years of lived-experience of Fr. Peter Geremia, PIME a zealous Missionary, a Tribal – Filipino advocate, Justice and Peace promoter, a Spiritual guru, and a Father of the poor. Reading this book will not only give you a glimpse of his hard work in mission and an insight of what a missionary work has contributed a lot in the growth and development of the Tribal-Filipino faith-communities and Basic Ecclesial Communities in the Diocese of Kidapawan. His dedication and zeal in the mission of building God’s Kingdom has influenced many to become priests, dedicated and committed lay leaders in the Gagmay’ng Kristohanong Katilingban (GKKs) and parishes, educators, and advocates of peace and reconciliation. May this written testimony of Fr. Peter inspire more baptized Christians to commit and participate in the mission of evangelization for the growth of the Kingdom of God in the Diocese of Kidapawan and the whole Church.
