Abstract
Professor Christopher Stead was Ely Professor of Divinity from 1971 until his retirement in 1980 and one of the great contributors to the Oxford Patristic Conferences for many years. In this paper I reflect on his work in Patristics, and I attempt to understand how his interests diverged from the other major contributors in the same period, and how they were formed by his philosophical milieu and the spirit of the age. As a case study to illustrate and diagnose his approach, I shall focus on a debate between Stead and Rowan Williams about the significance of the word idios in Arius's theology (in the course of which I also make some suggestions of my own about the issue).
