These are days of small books and single volumes. Multi-volume sets are a rare and endangered species. The completion of Horton Davies's five-volume set on Worship and Theology In England is a major achievement in our age, and an uprecedented one in any age. Never before has the worship life of an entire people for four and one-third centuries received such a balanced and careful scrutiny. Over fifteen years of research have borne plentiful and rich fruit. This work of the Henry W. Putnam Professor of Religion at Princeton University marks an achievement in liturgical studies unequalled by living scholars in the English-speaking world.
