In 1860, he expanded his "Elements of the Gospel Harmony" essay into an "Introduction to the Study of the Gospels". Westcott's work for Smith's "Dictionary of the Bible", notably his articles on "Canon," "Maccabees", and "Vulgate," led to the composition of his subsequent popular books, "The Bible in the Church" (1864) and a "History of the English Bible" (1869). To the same period belongs "The Gospel of the Resurrection" (1866). It recognised the claims of historical science and pure reason. At the time when the book appeared, his method of apologetic showed originality, but was impaired by the difficulty of the style.
