This introduction to the origins of Christian worship illuminates the importance of ancient Christian worship practices for contemporary Christianity. Andrew McGowan, a leading scholar of early Christian liturgy, takes a fresh approach to understanding how Christians came to worship in the distinctive forms still familiar today. Deftly and expertly processing the bewildering complexity of the ancient sources into lucid, fluent exposition, he sets aside common misperceptions to explore the roots of Christian ritual practices--including the Eucharist, baptism, communal prayer, preaching, Scripture reading, and music--in their earliest recoverable settings. Students of Christian worship and theology as well as pastors and church leaders will value this work.
