When Common Worship was introduced, a need for a serious and scholarly commentary on the whole range of its texts became apparent. A Companion to Common Worship provides an historical survey of the origins and development of many rites from New Testament times, through the Middle-Ages and Reformation, up to the present day. The parts of each rite are examined in a detailed commentary that includes a comparison with the ASB and other contemporary liturgies, followed by a short list of books for further reading.
