was still contested in 394. He then travelled to Jerusalem where Cyril of Jerusalem faced opposition from local clergy due to the fact that he had been ordained by Acacius of Caesarea, an Arian heretic. Gregory's attempted mediation of the dispute was unsuccessful, and he himself was accused of holding unorthodox views on the nature of Christ. His later reign in Nyssa was marked by conflict with his metropolitan, Helladius. Gregory was present at a 394 synod convened at Constantinople to discuss the continued problems in Bostra. The year of his death is unknown. Theology The traditional view of Gregory is that he was an orthodox Trinitarian theologian, who was influenced by the Neoplatonism of Plotinus and believed in universal salvation following Origen. However, as a highly original and sophisticated thinker, Gregory is difficult to classify, and many aspects of his theology are contentious among both conservative Eastern Orthodox theologians and Western academic scholarship. This is often due to the lack of systematic structure and the presence of terminological inconsistencies in Gregory's work. Conception of the Trinity Gregory, following Basil, defined the Trinity as "one essence [οὐσία] in three persons [ὑποστάσεις]", the formula adopted by the Council of Constantinople in 381. Like the other Cappadocian Fathers, he was a homoousian, and Against Eunomius affirms the truth of the consubstantiality of the trinity over Eunomius' Aristotelian belief that the Father's substance is unengendered, whereas the Son's is engendered. According to Gregory, the differences between the three persons of the Trinity reside in their differing hypostatic origin, and the triune nature of God is revealed through divine action (despite the unity of God in His action). The Son is therefore defined as begotten of the Father, the Holy Spirit as proceeding from the Father, and the Father by his role as progenitor. However, this doctrine would seem to subordinate the Son to the Father, and the Holy Spirit to the Son. Robert Jenson suggests that Gregory implies that each member of the Godhead has an individual priority: the Son has epistemological priority, the Father has ontic priority and the Spirit has metaphysical priority. Other commentators disagree: Morwenna Ludlow, for instance, argues that epistemic priority resides primarily in the Spirit in Gregory's theology. Modern proponents of social trinitarianism often claim to have been influenced by the Cappadocians' dynamic picture of the Trinity. However, it would be fundamentally incorrect to identify Gregory as a
