Socinian controversy
The Socinian controversy in the Church of England was a theological argument on christology carried out by English theologians for around a decade from 1687. Positions that had remained largely dormant since the death in 1662 of John Biddle, an early Unitarian, were revived and discussed, in pamphlet literature.
This controversy was part of a larger debate after the Act of Toleration 1689, which excluded from its eligibility for high offices anti-trinitarian Christians as well as Roman Catholics. By the end of the 1690s it had become clear that, for many years, religious tolerance would not be extended. Across all media, the Blasphemy Act 1697 prohibited any preaching, teaching, writing or "advised speaking" of Christians for unitarianism for 116 years. The Doctrine of the Trinity Act 1813 then re-enables Christians, subject to any tenets of a church they wish to remain part of, to critique and practise against the equality within the Holy Trinity, but kept a prohibition for advised speaking or writing as to more than one God among Christians.
During this decade the arguments had become well aired, and the Church of England was proven to be more diverse in theological understanding than much law and treatise had suggested. An unintended consequence of strong attacks by theologically orthodox Anglicans, in the longer term, was a resulting greater de facto tolerance extending among English Protestants, after a halt was called to the aggressive orthodoxy of William Sherlock. This tolerance, becoming a hallmark of Latitudinarian views as they changed into low church liberality, worked its way out in impactful controversies; the splintering away of many congregations and even some parish priests of the eighteenth century, for which see English dissenters, "nonconformism", ecclesiastical separatism, and 17th-century denominations in England.
Detailed history
The Socinian argument, of which little had been heard for 25 years, was revived in 1687 by the publication of a ‘Brief History’ of the unitarians, as they from now on often designated themselves. There followed a sheet of ‘Brief Notes’ on the Athanasian creed.These two publications prompted William Sherlock's Vindication of the doctrine of the Trinity. Shortly afterwards the subject was also taken up by John Wallis. The Socinians and others accused Sherlock's ‘Vindication’ of tritheism; and reputedly this work had the effect of making a Socinian of William Manning and an Arian of Thomas Emlyn. Sherlock's position was attacked also by another Anglican, Robert South, with a mixture of irony and invective.
Sherlock's doctrine, as preached at Oxford by Joseph Bingham, was condemned by the hebdomadal council, as ‘falsa, impia et hæretica’. Sherlock defended himself in an ‘Examination’ of the decree.
On 3 February 1696 William III addressed to the hierarchy ‘Directions,’ drawn up by Thomas Tenison, prohibiting the use of ‘all new terms’ relating to the Trinity. In his ‘Present State of the Socinian Controversy’ Sherlock in practical terms gave up on the positions that had been impugned.
Literature related to the argument was still voluminous, however, in the period up to 1704. One notable reader and student of the debate was John Locke.
