Hymns and the music the church sings are tangible means of expressing worship. As worship is one of the central functions of the church and it occupies a prime focus, a renewed sense of awareness to our theological presuppositions and cultural cues must be maintained to ensure a proper focus in worship. Hymns and Hymnody is an introductory textbook in three volumes describing the most influential hymnists, liturgists, and musical movements of the church. This academically grounded resource evaluates both the historical and theological perspectives of the major hymnists and composers that have impacted the church over the course of twenty centuries. Volume 1 explores the early church and concludes with the Renaissance era hymnists. Each chapter contains five elements: historical background, theological perspectives communicated in their hymns/compositions, contribution to liturgy and worship, notable hymns, and bibliography. The missions of Hymns and Hymnody are to provide biographical data on influential hymn writers for students and interested laypeople, and to provide a theological analysis of what the cited composers have communicated in the theology of their hymns. It is vital for those involved in leading the worship of the church to recognize that what they communicate is in fact theology. This latter aspect is missing in accessible formats for the current literature.
