Alan P. F. Sell is a scholar and ecumenist who has taught courses, conducted worship, and delivered great lectures in many parts of the world. Following two pastorates and a period in British higher education, he became Theological Secretary of the World Alliance of Reformed Churches (Presbyterian and Congregational), Geneva, and then held the Chair of Christian Thought in the University of Calgary, Canada. Since 1992, he has been at The United Theological College in Wales.Throughout the trilogy Doctrine and Devotion the author seeks to communicate the Christian faith and foster a devotion that has implications for daily living. Alan P. F. Sell does this by presenting the major Christian doctrines -- God the Father, Christ the Son, and the Holy Spirit -- as they are found in the Bible, as believers have confessed them through the ages, and as they relate to Christian witness at the dawn of a new millennium.The spirit of gentleness and of a rushing mighty wind draws Christians to the fatherly God of holy love and to partnership with Jesus Christ in the church's roles of ministry, mission, and companionship with one another. The doctrine of the Holy Trinity sometimes seems hard to grasp, but in part 3 of Doctrine and Devotion the author not only expands on the importance of Spirit but discusses the interrelationships of Father, Son, and Holy Spirit as expressed in worship and in daily life.
