Abp. of Canterbury from 1945 to 1961. While Bp. of London (1939–45) he showed great administrative skill in dealing with the pastoral reorganization necessitated by war damage and as Chairman of the Churches' Main War Damage Committee. In 1946 he preached an influential sermon on reunion at Cambridge, and in 1960, when he travelled to meet the Oecumenical Patriarch of Constantinople and Pope John XXIII, he was the first Abp. of Canterbury to visit the Vatican since 1397. He encouraged the formation of new Provinces and so divested himself of authority over the African and Asian parts of the Anglican Communion.
