This contribution is based on a short extract from my Master’s dissertation submitted during 2016. Saint Gregoy of Nyssa writes at length about the mystical experience of God that comes via ascent.  Basing his work on both Hellenistic philosophy and the preceding theologians, he asserts that the soul is capable of ascending a ladder, or mountain, towards God, made possible and empowered by the Christ. As the soul climbs, so it experiences a deeper, transcendent encounter of God, that for Moses culminated on Mount Sinai in what he describes as a “luminous darkness”. I set out to show that Saint Gregory of Nyssa was both highly theoretical and strongly practical in his approach. His profoundly rooted theology is evocatively written, and he has an undoubted ability to give clarity to complex ideas by earthing them in everyday life. He is an excellent learning facilitator and as such both inspires and equips his audience. It is my assertion that the work of Saint Gregory of Nyssa continues to have relevance for the modern expression of faith, and deserves a wider audience.
