As the global climate crisis worsens, many churches have sought to respond by instituting a movement to observe a liturgical season of creation. Scholars who have pioneered the connections between biblical scholarship, ecological theology, liturgy, and homiletics provide here a comprehensive resource for preaching and leading worship in this new season. Included are theological and practical introductions to observance of the season, biblical texts for its twelve Sundays in the three-year lectionary cycle, and astute commentary to help preachers and worship leaders guide their congregations into deeper connection with our imperiled planet.
