Reformed theology in the Church of England

Calvinism in the Church of England refers to the predominant influence of Reformed theology within the Church of England in the late sixteenth and most of the seventeenth century, with roots in the English Reformation and continuing influence beyond the seventeenth century. During the reign of Elizabeth I, many leading bishops and theologians embraced Calvinist doctrines, particularly on predestination, creating what historians have called a "Calvinist consensus". This consensus was expressed in the Thirty-nine Articles, especially Article 17, and in the Lambeth Articles of 1595, though the latter were never officially authorised by the crown.

In the early seventeenth century, Calvinism shaped the outlook of much of the English clergy and Puritan movement, but it was increasingly challenged by Arminian and Laudian currents within Anglicanism. The resulting conflicts contributed to the English Civil War, during which the Westminster Assembly produced the Westminster Confession of Faith as a systematic Calvinist confession more clearly Calvinist than the Thirty-nine Articles. After the Stuart Restoration and the 1662 Act of Uniformity, Calvinist ministers who could not conform to the Book of Common Prayer and bishops were expelled in the Great Ejection, marking the emergence of English Nonconformism.

Although Calvinism ceased to dominate the Church of England after 1662, elements of Reformed theology continued to influence Anglican thought, especially among Evangelicals in the eighteenth century.
