Thomas Vincent (May 1634–October 15, 1678) was an English Puritan preacher and author, celebrated for his courageous ministry during the Great Plague of London and his influential writings on Christian doctrine. Born in Hertford, Hertfordshire, to John Vincent, a minister ejected in 1662, and an unnamed mother who died in his infancy, he was raised by his stepmother, Amy. Educated at Westminster School and Christ Church, Oxford, he earned a B.A. in 1652 and an M.A. in 1654, excelling in divinity under John Owen and Thomas Goodwin. Initially a Presbyterian, he served as chaplain to Robert Sidney, Earl of Leicester, and rector of St. Mary Magdalene, Milk Street, London, from 1656 until his ejection under the 1662 Act of Uniformity for nonconformity. Vincent’s preaching career peaked during the calamitous years of 1665–1666. Refusing to abandon London during the Great Plague—unlike many clergy—he stayed in Hoxton, preaching weekly and visiting the sick, even as 68,000 perished, including seven from his own home. His firsthand account, God’s Terrible Voice in the City (1667), vividly captured the plague and Great Fire, urging repentance. After 1662, he led a nonconformist congregation in Hoxton, briefly imprisoned in 1670 for unlicensed preaching, and ran a dissenting academy training ministers like Nathaniel Vincent, his brother. His works, including The Shorter Catechism Explained (1674) and Christ’s Certain and Sudden Appearance to Judgment (1667), reflected his pastoral heart and Puritan zeal.
