Written around 1350 by an anonymous author, this is a simple yet profound book about life in God as it translates into life in the world. This translation was based on the Reformer's edition of 1518.

"Liturgical Theology" is often a convenient label for any theology that has loosely to do with worship or Eucharist. In this innovative book, David Fagerberg distinguishes liturgical theology from a general theology of worship. He proposes two defining attributes of liturgical theology: (1) "lex orandi": It is manifested in the Church's historical rites. (2) "theologia prima": It is theology done by the liturgical community. Theologia Prima is a thorough revision of Dr. Fagerberg's groundbreaking, What Is Liturgical Theology? A Study in Methodology (1992). It contains three new chapters as well as well as more anecdotal material derived from Dr. Fagerberg's extensive experience as a teacher and theologian.

The Book of the Perfect Life crystallized the mystical experience of the late Middle Ages, yet still speaks to seekers today. Martin Luther wrote of this 14th century devotional work that "next to the Bible and St. Augustine, no other book has come to my attention from which I have learned-and desired to learn-more concerning God, Christ, man and what all things are." Theologica Deutsch-the title this work has most commonly appeared under- has been through 190 editions in ten languages throughout its 600-year history. Now drawing on the latest German critical edition of the work, David Blamires brings us the definitive English translation of this classic mystical work, The Book of the Perfect Life.
