second Viscount Halifax. A High Churchman, he was associated with the foundation of SSJE in 1866, and as President of the English Church Union (1868–1919 and 1927–34) he was involved in most of the ecclesiastical controversies of his time. Friendship with E. F. Portal led him to promote reunion between the C of E and the RC Church; with Portal he was responsible for initiating conversations in 1894–6 (terminated by ‘Apostolicae Curae’). After the Lambeth Appeal of 1920, he reopened the matter with Cardinal D. J. Mercier, with whom he arranged the Malines Conversations (q.v.).
