This manual provides sacristans with all the important and relevant information for their service. It offers a compact and clear overview of the use, storage, and care of liturgical items, vestments, and liturgical books. A brief introduction to the liturgy explains the various forms of worship, the sacraments, and the church year—always with a special focus on what sacristans need to know. The most common altar server duties, a quick course for substitutes, a glossary of terms, and a detailed index complete the book. An indispensable work aid for custodians, sacristans, and vergers.
