In celebration of Alister E. McGrath’s sixty-fifth birthday in 2018, this Festschrift aims to highlight him as a lauded scholar, who exemplifies an interface of science, theology, and religion. It comprises works by McGrath’s theological allies and colleagues from diverse ecclesial homes including Graham Ward, Oliver Crisp, Tony Lane, Sung Wook Chung, Randall Zachman, Veli-Matti Kärkkäinen, Jonathan Wilson, Jeffrey P. Greenman, Robert Kolb, Sister Benedicta Ward, Michael Lloyd, Bethany Sollereder, and Patrick Franklin. Critical but appreciative is the posture with which these contributors engage the wide range of McGrath's own scholarly pursuits and publications. This volume, edited by Dennis Ngien, covers these themes that are central to the life and witness of the church: atonement, Christology, Trinity, eschatology, mission, Reformation, science, nature, culture, evangelism, and theodicy—there is much to ponder and reap here. Readers will join with the contributors and pay tribute to McGrath who has risen to a life of significance as a scientist turned theologian, professor, author, Christian apologist, and churchman.
