He was a prominent member of his Connexion, being Moderator of the Association in the East in 1951, and of the General Assembly in 1957. He delivered the Davies Lecture in 1933 on ‘The Kingdom of God in the light of the apocalyptic ideas of the Bible’, [parts of which appeared in the Monthly Treasury], and a Welsh version was published in 1935. He wrote a great deal for Cymru, and the periodicals of his denomination. He published, among other works, two volumes of children's stories in Welsh (1921 and 1927); two volumes in Welsh on the Bible (1922; 1932), one on Christian doctrine (1953), a volume on the history of civilisation (1927), and Athrofa'r Bala (a history of Bala College, 1937). His work as a preacher, teacher, and author was characterized by order and lucidity. He took an interest in education; he edited Sunday school textbooks for his denomination for years. He was also the literary editor of the Society for Religious Education in Wales and wrote a syllabus for religious instruction in the schools of Wales (1945-46). He took an interest in the School of Social Service for Wales, and wrote one of the booklets of that movement, Hamdden yr adolesent yng Nghymru (1929). The United Nations Organisation published another pamphlet of his, on Sunday school teachers and world peace (1934). He was a scholar with a clear, analytic mind, and paid great attention to detail.
