Biblical infallibility is a sine quo non in any evangelical theology. Nevertheless, the interpreter may be unduly influenced by psychological or cultural factors or little exposed to other religious traditions and further discoveries about the universe. These often-unconscious sources of interpretation inevitably impact scriptural exegesis, theological interpretation, and doctrinal definition, engendering internal tensions and aporias in questions such as the relation between divine sovereignty, evil, and unjust suffering, and the validity of other religious traditions. This third and last volume of an evangelical Christian systematic theology, which takes account of psychological wellbeing, cultural diversity, and religious plurality, reassesses and reinterprets core Christian doctrines concerning God and humanity, in dialogue with major classical, medieval, and modern theologians including Augustine, Anselm, Aquinas, Luther, Calvin, Schleiermacher, and Barth.
