Of this work, the neurologist and writer on disability Oliver Sacks commented in "The New Yorker", "There has never been, to my knowledge, so minute and fascinating (and frightening) an account of how not only the outer eye, but the 'inner eye', gradually vanishes with blindness; of the steady loss of visual memory, visual imagery, visual orientation, visual concepts... of the steady advance or journey... into the state which he calls 'deep blindness'." Hull's experiences led him into further consideration of blindness and disability, particularly in a Christian context on which he wrote a number of challenging articles. He also wrote another book, "In the Beginning there was Darkness: A Blind Person’s Conversations with the Bible" (2001') in which he interpreted the Bible as the product of a sighted culture, with a negative attitude towards blindness. In 1988, Hull initiated Cathedrals through Touch and Hearing, a scheme which has provided 17 English cathedrals with wooden models and elevated ground plans for the benefit of blind visitors. In 2003 the Vice President of the Republic of China presented him with a Global Love of Life Award given by the Chou Ta-Kuan Cultural and Education Foundation of Taiwan to honour those who have contributed to the cause of disabled people or have overcome personal disability. Hull read theology at Cambridge University from 1959 to 1962, and received a PhD in theology from the University of Birmingham in 1969, for a study of the background to the miracles of Jesus, in the magical world of the first century. This was the basis of his book of the same title, "Hellenistic Magic and the Synoptic Tradition" (1974). Alongside his work on religious education, he was concerned with the theology of education, the theology of disability, and the theology of Christian mission, including a critique of money. Some of Hull's writings on the last subject have been edited and translated into German, and published as "Gott und Geld" ('God and Money') (2000). (Book not available in English.) After becoming a professor emeritus at the University of Birmingham, his research and teaching interests turned to issues of practical theology. In 2004 he took up a post at the Queen's Foundation for Ecumenical Theological Education, Birmingham, as Honorary Professor in Practical Theology. There he was involved with the training of students for the Anglican and Methodist ministries, particularly in the area of prophetic ministry which concerns leadership on questions of social justice – questioning and criticising society in the name of the God of justice and peace.
