1992 0-7734-9542-8 This is a major study of Gregory of Nyssa's thought, which has been unduly neglected and underestimated by scholars. The relationship between grace and freedom is among the more significant focal points in Christian theological reflection, and Gregory of Nyssa's thought in this area is rich and provides abundant material for detailed analysis of the Eastern alternative. This study examines his view of grace and freedom within his own historical setting, and particularly in the context of his thought as a whole. It is a significant new analysis of centithetical thinking, which is important in much patristic and Byzantine theology.
