J. I. Packer (1926–2020) was a British-born Reformed Anglican theologian who taught for many years at Regent College in Vancouver. His Knowing God (1973) introduced millions to the doctrines of grace, and his work Evangelism and the Sovereignty of God remains a beloved reconciliation of Calvinist conviction with passionate evangelistic concern.

William Perkins (1558–1602) was an English Reformed theologian and fellow of Christ's College, Cambridge, whose lectures at St Andrew the Great made him the foremost Puritan voice of the Elizabethan era. Dubbed the "father of Puritanism," his works on predestination, assurance, and practical divinity outsold Calvin and Beza in England and shaped a generation of Puritan ministers on both sides of the Atlantic.

Cornelius Van Til (1895–1987) was a Dutch-born Reformed philosopher and apologist who taught at Westminster Theological Seminary from its founding until 1972. He developed the presuppositional method of Christian apologetics, arguing that the triune God of Scripture is the necessary precondition for all human knowledge and rationality.

Joseph Charles Philpot (1802–1869) was an Oxford-educated Anglican curate who resigned his orders in 1835 to become a Strict and Particular Baptist minister. He is remembered for his deeply experiential preaching and as the long-serving editor of The Gospel Standard magazine, which shaped English Strict Baptist piety for generations.

Samuel Pike (1717–1773) was an English Congregationalist minister and Calvinist theologian who pastored at St. Martin's-le-Grand in London. He is best known for his Persuasive to a Holy Life and his Familiar Introduction to the Holy Scriptures, works marked by clear Calvinistic piety and practical application.

Arthur W. Pink (1886–1952) was a self-taught English Reformed writer whose vast body of devotional and theological works — largely unknown in his lifetime — found a wide readership through Banner of Truth reprints after his death.

John Piper is the founder of desiringGod.org and chancellor of Bethlehem College and Seminary, having served as senior pastor of Bethlehem Baptist Church in Minneapolis for thirty-three years. His influential book Desiring God introduced the concept of "Christian Hedonism" and helped bring Reformed theology to a new generation of evangelicals.

William Swan Plumer (1802–1880) was an American Presbyterian minister and theologian who pastored prominent churches in Richmond, Baltimore, and Allegheny before serving as professor of theology at Columbia Theological Seminary. He authored more than twenty-five books, including substantial commentaries on Romans, Hebrews, and Psalms.

Kerry Ptacek is an Associate Reformed Presbyterian pastor and author who advocates for the recovery of household worship. He is the author of Family Worship: Biblical Basis, Historical Reality, Current Need (1994), a historically grounded examination of the biblical warrant for regular family devotions.
