After briefly returning to Wells in 1919, he was appointed as chaplain and Fellow of Lincoln College, Oxford, moving in 1921 to New College as Fellow, Tutor and Dean of Divinity. He was appointed as Dean Ireland's Professor of the Exegesis of Holy Scripture in 1934, and was then less involved in college affairs: up until then he had undertaken many administrative tasks to make up for the lesser teaching burden that he had compared to other colleagues at New College. He resigned his professorship in 1949; after he ceased to be a Fellow of New College in 1950, he was appointed to an Extraordinary Fellowship at Lincoln College.[1]
He was regarded as a "lucid and accurate" lecturer.[1] He concentrated his work on the four gospels, particularly the Gospel of Mark. He was described as "zealous in promoting Biblical research" at Oxford, but published little as he was "a hesitant writer with an unfeigned horror of inaccuracy".[1] However, his St John's Gospel: A Commentary was published posthumously in 1957, edited by C F Evans. His 1934 Bampton Lectures, History and Interpretation in the Gospels, were regarded even by those who disagreed with him as "an important contribution to the study of the New Testament."[1]
