In November 2001, James E. Loder Jr., Professor of the Philosophy of Christian Education for forty years at Princeton Theological Seminary, suddenly died. He was a creative and profound thinker who had just completed a promising book. In it he developed a compelling interdisciplinary model to disclose how the divine Spirit affirms, reconstitutes, and transforms the human spirit to bring new energy and creativity into human experience. He called it redemptive transformation. You now hold that book in your hands. Those who know Loder's work are confident that Educational Ministry in the Logic of the Spirit, though delayed for over fifteen years, will still become the best introduction to his complex thought. More important, it offers the imaginative means by which we may learn to attune ourselves and our faith communities to what God is doing in our fractured, distracted, and self-destructive world to bring about a revolution of love--the fruit of Christ's Spirit and the center of our human vocation.
