Gregory of Nyssa is firmly established in today's theological curriculum and is a major figure in the study of late antiquity. Andrew Radde-Gallwitz presents a reading of the works in Gregory's corpus devoted to the dogmatic controversies of his day. An important achievement for the theological space in generally. The philological analyses like the historical information offered and the contextualisation of the texts, linked also with the underlining of the actual dimension of some works, are some of the strong points of the book of Andrew Radde-Gallwitz.
