In what may be regarded as his magnum opus, Clark Pinnock explores the vital Christian doctrine of the Holy Spirit. Writing out of wide learning and deep personal passion, he points the way to restoring the oft-neglected Spirit to centrality in the life and witness of the church. Pinnock's book is both catholic―respecting the beliefs and worship of the historic church―and evangelical―drawing particularly on the heritage of the Reformation. Always in sight is the mission of the church, because "people want to meet the real and living God and will not be satisfied with a religion that only preaches and moralizes." For this second edition, theologian Daniel Castelo draws from his experience using Flame of Love in the classroom to add notes with helpful commentary and brief reflections on each chapter's main themes and contributions. While the classic text is preserved, the book becomes even more accessible to contemporary readers. "What if theology and life were seen through a Holy Spirit lens? Anticipating and contributing toward a Third Article Theology, Pinnock's Flame of Love invites the reader on a thought-provoking ecumenical journey of heart and mind through the pneumatic foundations and implications of Christian theology. Castelo's winsome commentaries and helpful updates add pedagogical value to this revised edition of Pinnock's classic for a new generation of readers." -- Leopoldo A. Sánchez M., professor of systematic theology and Werner R. H. and Elizabeth R. Krause Professor of Hispanic Ministries, Concordia Seminary, St. Louis, Missouri "I am thrilled to see this new edition of Pinnock's classic on pneumatology appear with Daniel Castelo's brilliant commentary at key points in the text. Castelo raises issues important for contextualizing and thinking further about the points raised by Pinnock. I can't wait to use this in the classroom." -- Frank D.
