Christian worship is always undergoing change as it adapts to particular contexts and concerns. This collection of essays explores ways: 1) that liturgical change happened to address particular historical and theological concerns; 2) that worship and preaching are currently undergoing transition; and 3) that aspects of worship are in need of transformation in order to address primary issues of our time with a focus on environmental and ecological concerns. Spacial attention is paid to the role of the Sacraments and to preaching with an emphasis on the need to connect worship with daily life. These essays show readers ways that liturgical renewal worked in the past as well as offer a persuasive case for continual renewal that responds to key issues in our contemporary lives.
