This collection of essays explores the rich and diverse intersections between the world of liturgy and the worlds of creation and the cosmos. The intersections highlighted here include biblical, historical, visual, and musical materials as well as contemporary theological and pastoral challenges for worship today. The essays gathered in this volume were first presented at the 2018 Yale Institute of Sacred Music Liturgy Conference and are here made available to a wider audience. These essays are responses to the unprecedented attention to ecological and cosmological concerns, which call for sustained engagement by scholars and practitioners of liturgy.
