Dr. Isaac brings a diverse theological background to Gordon-Conwell Theological Seminary. He has studied at a holiness seminary, a Lutheran seminary, and a Jesuit university. This experience in a number of different Christian traditions has given him an appreciation of the rich expressions found within the Church.
Teaching in the area of Christian Thought has allowed Dr. Isaac’s wide interests to be expressed through courses on Martin Luther, Dietrich Bonhoeffer, Reformation Era Spirituality, Great Confessions of the Faith, Popular Religion in Nineteenth-Century America, the Anabaptists, and other courses that regularly appear in the Church History sequence.
Dr. Isaac has lectured both nationally and internationally on Luther and other topics before audiences as diverse as the Society of the Holy Trinity, Lutheran Theological Seminary in Kobe Japan, the Annual Convocation of the North American Lutheran Church, a Reformation gathering at UMass Lowell, and Boston’s Park Street Church. He has served as pastor or interim pastor in churches in the Advent Christian denomination from Portland, Oregon to Goodwin’s Mills, Maine.
A regular participant and seminar leader in the International Congress on Luther Research, Dr. Isaac is the author of Prayer, Meditation, and Spiritual Trial: Luther’s Account of Life in the Spirit. This book seeks to show the dynamic and powerful spirituality of Luther in the context of his theological vision. The book incorporates Luther’s comments on the Holy Spirit—a topic that is often neglected in Luther studies—and highlights Luther’s recognition that true spirituality must speak about reversal, struggle, and trial, which are inevitable wherever spiritual growth is taking place.
His hobbies include traveling, gardening, and international cooking. Dr. Isaac is an admirer of the paintings of Lucas Cranach (the Elder as well as the Younger) and has a growing collection of paintings by Sadao Watanabe (1913 – 1996). He and his wife, Beth, have two grown children and live in Wenham, MA.
