In justification of its idea of a "via media", the Oxford Movement attributed this position to the works of the Elizabethan theologian Richard Hooker and in particular his book "Lawes of Ecclesiastical Polity", which is accepted as a founding work on Anglican theology, a view of Hooker promoted by John Keble, who was one of the first to argue that English theology underwent such a "decisive change" in Hooker’s hands. However, Hooker does not use the phrase ""via media"" or "middle way" or the word "Anglican" in any of his works; the attribution of "via media" to him is much later. Hooker's work concerned the form of Protestant church government as an argument against the extreme advocates of Puritanism, arguing that elements of Church of England practice condemned by the Puritans, in particular the "Book of Common Prayer" and the institution of bishops, are proper and accord with Scripture. Later theologians analysed Hooker's approach to the particular doctrine of justification by faith as a middle way between the predestinationism of the extreme Calvinists and Lutheran and Arminian doctrines.
