Book excerpt: Historic changes are occurring in the convergence of worship styles throughout the Christian church. Christians across the theological spectrum are seeking to learn from their own tradition's roots and from the liturgical expressions of believers in other times and places. Here worship expert Clayton Schmit examines worship in church settings around the globe and provides a practical manual for shaping liturgies that are informed by and relevant to contemporary missional contexts. The book broadens current ecumenical worship conversations, reveals insights drawn from the church at worship in the world, and argues for a common understanding of a theology of worship.
