Dr Brendan Harris


I have a long-standing connection with Oriel College – I read Philosophy and Theology here as an undergraduate, before moving on to Durham for an MA in Christian Theology.

I did my PhD in the USA, at Emory University, where I wrote my dissertation on the 4th century bishop and theologian Gregory of Nazianzus. I graduated in in 2019, returning to Oxford for a one-year post as Departmental Lecturer in Patristics and Tutor in Theology at Christ Church, before taking up my new post at Oriel in 2020.

Research Interests

I am currently working on a project investigating the soteriology of Gregory of Nazianzus, one of the three so-called ‘Cappadocian Fathers’, with a particular focus on Gregory’s concept of “theosis” or “deification”  as the goal of salvation. I am also currently working on translating Gregory’s Carmina Moralia or “Moral Poems”. More generally, I am interested in the development of Christology and Trinitarian theology in the 4th century, and in contemporary analytic appropriations of patristic thought.
