What is theology, and how can it still speak with meaning today? This book is both a personal and scholarly journey into fundamental theology, reimagined through dialogue with youth ministry and the lived experiences of young people. It reflects on faith not as a closed system of doctrines but as a dynamic story--an auto/Theo-biography--where human lives and God's presence intertwine. Drawing on Central European contexts, encounters with students, and the wisdom of internationally renowned mentors, the author explores how theology can be communicated in a secular yet spiritually searching culture. Here theology is not reserved for specialists but opens into conversation with everyday life, culture, and future generations. Challenging the boundaries between theory and practice, this book calls for a theology that is understandable, existentially relevant, and rooted in stories of faith, hope, and love. At once deeply autobiographical and widely dialogical, it shows how fundamental theology can meet youth ministry and youth theology to inspire renewal, mutual learning, and a rediscovery of God in surprising places.
