The book, which has become a standard work and is presented here in an updated new edition, answers all questions about worship today - organized alphabetically and supplemented with an additional index. It contributes to a deeper understanding of liturgical life for all those who are engaged in pastoral work, whether professionally or as volunteers, and provides inspiration for active participation in worship. Each article is structured as follows: explanation of terms and concepts, origin and historical development, current form and order, as well as pastoral notes where applicable.
