Research Interests

Dissertation synopsis:

The aim of my PhD is to address the following question: how did the doctrine of divine simplicity (DDS) fit within Patristic Trinitarian theology? This question is important because DDS has become a controversial issue in systematic and philosophical theology. On the one hand, historical theologians recognised the centrality of DDS in Patristic Trinitarian thought. On the other hand, many modern critics of DDS cast doubt on the internal coherence of the doctrine and its compatibility with the Trinitarian doctrine of God. However, much of the debate is based on a restricted understanding of DDS, which is the version traditionally attributed to Augustine, Anselm and Aquinas. It is my contention to argue that a richer understanding of DDS contextualised within the late antique metaphysical context is required to move the debate forward. The primary outcome of my PhD is therefore an assessment of DDS and its compatibility with Patristic Trinitarian theology that is grounded on a firmer historical foundation and a wider intellectual context. My aim is to provide a critical reconstruction of the different senses of divine simplicity understood by various Patristic writers and to trace how the context of application of this idea evolves from pre-Nicene to post-Nicene theology.
