Abstract

“Christianity is a μίμησις of the divine nature.” This definition of what it means to be a Christian, given by St Gregory of Nyssa in his letter De pro- fessione Christiana, employs a term commonly translated as “imitation” or “representation.” Even a brief study of some of the seminal sources of classical Greek thought, however, will show that the concept of mimesis surpasses any of these translations and effortlessly crosses the boundaries of the sphere of aesthetics, towards the fundamental questions of epistemology, metaphysics, ontology, and ethics. An analysis of Gregory’s letter, together with the related treatise De perfectione, will then show his nuanced familiarity with the subtleties of mimesis, which he consciously employs to arrive at his definition of Christianity. With this in hand, I will argue that even some of Gregory’s most perplexing scriptural exegesis in his homilies on the Song of Songs grows out of his coherent concept of mimesis, which ultimately is of fundamental importance to Gregory’s anthropology, cosmology, and Christology.
