Book excerpt: This book examines the historical development of the blessing of waters and its theology in the East, with an emphasis on the Byzantine tradition. Exploring how Eastern Christians have sought these waters as a source of healing, purification, and communion with God, Denysenko unpacks their euchology and ritual context. The history and theology of the blessing of waters on Epiphany is informative for contemporary theologians, historians, pastors and students. Offering important insights into how Christians renew Baptism in receiving the blessed waters, this book also proposes new perspectives for theologizing Christian stewardship of ecology in the modern era based on a patristic liturgical synthesis. Denysenko presents an alternative framework for understanding the activity of the Trinity, enabling readers to encounter a vision of how participants encounter God in and after ritual.
