The article revisits the use of certain Augustinian expressions and passages in the works of St Gregory Palamas, mainly regarding the Trinitarian reflections in man, the imago Dei, and the notion of eros (love). First, we present Palamas’ theology regarding the eros of the nous (intellect) for its logos. Second, we provide a brief review of the literature regarding the Augustinian presence in Palamas, and then continue with our assessment of this presence. We demonstrate that Gregory does indeed borrow phrases from Augustine, but he does not always use or incorporate the latter’s ideas; sometimes (e.g., in the case of the Filioque) he even comes to the opposite conclusion. In other words, despite similarities, one also finds crucial differences between Augustine’s and Palamas’ relevant approaches. Finally, four possible reasons—not often stressed in scholarship; the third probably mentioned for the first time—are proposed to explain why Palamas takes up the notion of eros from the Bishop of Hippo: a) the ‘eternal rest’ (ἀίδιος ἐπανάπαυσις) of the Holy Spirit on the Son; b) his willingness to oppose the Filioque; c) the appeal to a major notion in Palamas’ anthropology, namely the ‘vivifying power’ (ζωοποιὸς δύναμις) of the human soul; and d) the Holy Spirit’s ‘eternal resplendence’ (ἀίδιος ἔκλαμψις/ἔκφανσις). In conclusion, it is argued that this endeavour of Palamas could nowadays also inspire Orthodox theology in its effort to engage in dialogue with Western thought and in its attempt to articulate a genuine and persuasive voice in our era.
