In today's religiously plural world, theologian S. Wesley Ariarajah believes that authentic Christian faith demands that we rethink central concepts of the Christian theological tradition. Ariarajah's work is based on the conviction that some of the basic doctrinal formulations about God, Sin, Christ, Salvation, and Mission can in fact be rethought for our day, helping us to affirm deeply the Christian faith while still respecting other religious experiences in their distinctiveness. In this book, Ariarajah traces the biblical roots and theological developments of these doctrines, evaluates their coherence, and recommends new constructive options for a Christian theology of religions in the context of religious plurality.
