Rediscovering the Missing Jewel is a small-group course study designed around thirteen easy-to-understand sessions. Part 1, The Biblical Foundations of Christian Worship, explores worship in two sessions - one for the Old Testament and one for the New. Part 2, Worship from the Time of the Early Church through the Nineteenth Century, consists of six sessions that trace important developments from Justin Martyr to the congregations of African-American slaves in North America. Along the way, sessions are devoted to Eastern Orthodox, medieval Catholic, Reformation, and Protestant free church worship. Part 3, Worship Renewal in the Twentieth Century, traces strands of Chrsitian experience that directly influenced worship in many congregations today.
