This sequel to Gordon Lathrop's highly successful Holy Things is an exercise in liturgical theology, viewing the activities of worship as a means of defining and discussing the concept ?church.? It centers on community and assembly to discuss the sacraments. It focuses on ecumenism and inculturation as central test cases for a liturgically derived idea of church. In hopes of invigorating the local church, Lathrop explores the meaning of the term ?church, ? the relationship of the local liturgical assembly and other Christian assemblies (catholicity), the personal and communal character of liturgical assembly, the unity of the churches, the critical principles of liturgy and culture, openness to what is radically other, and liturgical evangelization. Lathrop's work grounds a notion of church that is personal yet communal, universal, but not triumphalistic.
