Margaret Barker (born 1944) is a British Methodist preacher and biblical scholar. She studied theology at the University of Cambridge, after which she has devoted her life to research in ancient Christianity. She has developed an approach to biblical studies known as Temple Theology.

She was president of the Society for Old Testament Study in 1998 and in July 2008 she was awarded the Lambeth degree of Doctor of Divinity by the Archbishop of Canterbury.

According to her, Sola Scriptura - the doctrine that the Bible is the supreme authority in all matters of doctrine and practice - has hindered rather than helped the understanding of Christianity.

"An Extraordinary Gathering of Angels is an exquisite visual and thoughtful study of the complex and fascinating world of angels in the Judaic-Christian tradition. Using more than 250 artworks, leading Biblical scholar and practicing theologian, Margaret Barker takes the reader on an extraordinary journey among the realm of angels. Barker makes this wonderful world accessible to all readers--mini essays make sense of the complex angel cosmology and detailed picture captions explain the meaning and significance of each angel type. Margaret also has included interviews she has taken with key theologians, artists and writers who have particular and sometimes differing viewpoints on the significance of angels.
