There have been several liturgical books used in American Presbyterian Churches. The main service book in current use is the Book of Common Worship (1993), published by the Presbyterian Church (U.S.A.) in cooperation with the Cumberland Presbyterian Church.
These books are not commonly used in the pews, but are resources for pastors in the preparation for Sunday worship, as well as for devotional use by church members and seminarians. Portions of these books are frequently found in the church bulletins, which become the liturgical booklet in many Presbyterian Churches.
American Presbyterians have both a directory for worship and a service book. There is often a confusion over the distinction between the two, and over the role of each. A "Directory for Worship" is a part of the constitution of the church and thus has the authority of church law. It provides the theology that undergirds worship, and includes appropriate directions for worship. It sets forth the standards and the norms for the ordering of worship. It does not have fixed orders of worship or liturgical texts.
The church’s service book, on the other hand, provides orders and texts for worship. It is in harmony with the directory and is approved for voluntary use. Where both a directory and a service book coexist, as in those churches served by the Book of Common Worship (1993), the service book sets forth, in orders of services and in liturgical texts, the theology and norms described in the directory. Service books have a longer history in the Reformed tradition than directories, and most churches in the Reformed community do not have directories but do have service books.
Reformed churches in the sixteenth century used service books. Ulrich Zwingli, Martin Bucer, and John Calvin all prepared worship forms for use in the congregations. John Knox, following Calvin, prepared The Forme of Prayers and subsequently a service book, the Book of Common Order, for use in Scotland. Liturgical forms were in general use in Switzerland, Germany, France, Italy, Holland, England, and Scotland.
However, the Reformation in England and Scotland after the death of Thomas Cranmer was formed in a very different context from that on the continent, where entire political entities were Reformed. The Reformed were thus able to prepare their own service books without interference. In England and Scotland those seeking to carry the reform from the continent had the difficult task of reforming within a state church hostile to Genevan-inspired reform. Even after the Scottish kirk was reformed under John Knox, it continued to endure English political and religious pressures, resulting in bitter conflict with the English crown.
