1466 – 1536
Desiderius Erasmus of Rotterdam (c. 1466–1536) was a Dutch Renaissance humanist, Catholic priest, and theologian whose scholarship and satire shaped early modern Christian thought. He championed a 'philosophy of Christ' centered on inner piety and moral reform rather than scholastic dogma or external ritual. Occupying a middle ground between Catholic orthodoxy and Protestant reform, he became the defining voice of Christian humanism in the sixteenth century.
