William Perkins (1558–1602) was an influential English Puritan theologian and fellow of Christ's College, Cambridge. One of the leading Reformed theologians of his generation, he was renowned for his plain preaching style and prolific writings on predestination, casuistry, and practical divinity. His commentary on the Epistle to the Galatians, covering the first five chapters, was published posthumously in 1607 alongside a supplement on the sixth chapter supplied by Ralph Cudworth. His works were widely read across Protestant Europe and exerted a formative influence on early Puritanism in England and New England.
