Thomas Collier (c. 1615 – c. 1691) was an English General Baptist preacher and Arian polemicist. Life Thomas Edwards in his Gangræna alleged that Collier originally was an illiterate carter or husbandman. In 1634, when he is described as of Witley, Surrey, he was complained of for obstinately refusing to pay taxations in the tithing of Enton, in the parish of Godalming, where he had an estate. The taxes included the ship money which Charles I of England had tried to levy without the consent of Parliament. Becoming a Baptist and preacher, though without academic education, he preached for some time in Guernsey, where he made many converts, but ultimately he and some of his followers were banished from the island for their views and turbulent behaviour, and he was imprisoned at Portsmouth. In, or perhaps shortly before, 1646 he was a preacher at York. About the same period there are traces of him at Guildford, Lymington, Southampton, Waltham, Poole, Taunton, London, and Putney; and in 1652 he was preacher at Westbury, Somerset. At one time he was minister at Luppitt and Up-Ottery, Devon. What became of him after the English Restoration is not clear, but it is probable that he was living in 1691, when the last of his numerous publications came from the press. He was the subject of Thomas Hall's The Collier and his Colours. His name is often mentioned with the Particular Baptist anti-trinitarian Paul Hobson (fl.1646-1670), who in 1663 conspired with a group of Fifth Monarchists and ex-Cromwell officers in the Farnley Wood Plot. The controversy surrounding his views was the catalyst for the writing and publication of the 1689 London Baptist Confession of Faith, still used at many Anglophone Particular Baptist churches. Works From the 1640s to 1691, in a series of booklets, he eventually turned to an Arian position against the Trinity. His works are: ‘Certain Queries, or points now in controversy examined,’ 1645. ‘The Exaltation of Christ,’ London 1646, with an epistle to the reader by Hanserd Knollys prefixed. Letters dated Guildford, 20 April 1646, and London, 2 May 1646: printed in Edwards's ‘Gangræna,’ ii. 51, 52, and in Benjamin Brook's Lives of the Puritans, iii. 28, 29. ‘The Marrow of Christianity,’ London 1647. ‘The Glory of Christ, and the Ruine of Antichrist, unvailed,’ 1647. ‘A Brief Discovery of the Corruption of the Ministry of the Church of England,’ Lond. 1647. ‘A
