George Slatyer Barrett, D.D. (1839-1916) was for 45 years (1866-1911) the minister of Prince's Street Congregational (now United Reformed) Church in Norwich, which under his tutelage was considered "one of the most influential Congregational churches in England." He was educated at University College, London; trained for the ministry at Lancashire Independent College, Manchester; was invested with the honorary degree of Doctor of Divinity at the University of St. Andrew's; and was the 1894 Chairman of the Congregational Union of England and Wales. As an author, he made several important contributions to theological literature, including his best-known work as editor of The Congregational Church Hymnal (1887).

With The Temptation of Christ, Barrett (ever the Nonconformist) challenges traditional thinking concerning Jesus' time in the wilderness by focusing his attention on its perceived psychological problems, positing "if instead of such a mechanical and literal interpretation of the narrative, we suppose that our Lord was tempted by doubts as to His own Divine plan?" An analysis that has been lauded as "wisely and reverently and spiritually interpreted, with ever fresh pertinence and power."
