In England, I have never met one either or at least the Anglicans I have known have never expressed adherence to Calvinist theology. I have met low-church evangelical Anglicans, however none of them have even adverted to being Calvinists.
Nevertheless I do know that in the formative years of Anglicanism, Calvinism was prominent. The Thirty Nine Articles show Calvinist influences, although they are more of a compromise between various Catholic, Lutheran and Calvinist beliefs. In the seventeenth century, the Anglican Church was practically inundated with Calvinist Puritans, especially after Cromwell won the Civil War. Parliament at that time had a majority Presbyterian orientation. “Anglo-Catholics” were nonetheless dominant in aristocratic and royalist centres of power.
After the Restoration of the Stuart Dynasty in 1660, I believe that the Puritans and Presbyterians were “cleansed” (their word not mine!) from the CofE. The Anglican Church in the British Isles became a much more self-confidently “non-Catholic” and “non-Conformist” (Puritan, Presbyterian, Anabaptist etc.) institution at this time. The public at large feared both “popery” (given the history of the Spanish Armada and French absolutism/treatment of Hugenots) and “Puritans”, which became a disdainful term at this period given how unpopular the Puritan attempt during Cromwell’s Protectorate to enforce morality and “godly reform” had been (ie banning taverns, theatres, Christmas, maypoles). While Catholicism was associated with continental Absolute Monarchy and superstition, Puritanism was associated with dour, lifeless misery, trenchant dogmatism and the tyrannical rule of Cromwell’s “Major-Generals” - the only time in British history in which the three kingdoms of England (including Wales), Scotland and Ireland were under a de facto military dictatorship.
As a result, the 18th century Church of England was far less ‘Calvinist’ than its predecessors had been. However it wasn’t “High Church” either as it largely became in the 19th century due to the Oxford Movement.
18th century Anglicanism saw itself neither as Calvinist or as Catholic. It was self-confidently its own position.
However there were still some prominent Calvinists in the Church during the 1700s, such as George Whitefield, who was the primary inspiration behind “
The First Great Awakening” in the British Isles and North America and perhaps is the most famous Anglican preacher in history. He baptized my 7x great grandfather George Smith in 1756 while on a preaching tour in Leeds. My ancestor was named after him and in every family tree I know of in which my Smith ancestors are present (they were an ancient and quite well-known family in Leeds) it is mentioned as a note of pride ie “**he was baptized by the *celebrated ***preacher George Whitefield, hence his Christian name” one says. I always found this detail interesting since George went on to become an early follower of John Wesley, the founder of Methodism, in Leeds (even worshipping regularly in Wesley’s own chapel when in London) and his son William co-founded the Methodist Missionary Society in 1813. John Wesley, despite being a close friend of Whitefield from their Oxford days in the “Holy Club”, was a famous anti-Calvinist Arminian.
My ancestors didn’t seem to bother about Whitefield’s Calvinism. They were proud of their connection to him despite being themselves Wesleyan Arminians
