Desiderius Erasmus Roterodamus, known as Erasmus of Rotterdam, or simply Erasmus, was a Dutch Renaissance humanist, Catholic priest, social critic, teacher, and theologian.
Erasmus was a classical scholar who wrote in a pure Latin style. He was an early proponent of religious toleration, and enjoyed the sobriquet "Prince of the Humanists"; he has been called "the crowning glory of the Christian humanists". Using humanist techniques for working on texts, he prepared important new Latin and Greek editions of the New Testament. These raised questions that would be influential in the Protestant Reformation and Catholic Counter-Reformation. He also wrote The Praise of Folly, Handbook of a Christian Knight, On Civility in Children, Copia: Foundations of the Abundant Style, Julius Exclusus, and many other works.
Erasmus lived against the backdrop of the growing European religious Reformation; but while he was critical of the abuses within the Church and called for reform, he kept his distance from Luther and Melancthon and continued to recognise the authority of the pope. Erasmus emphasized a middle way, with a deep respect for traditional faith, piety and grace, and rejected Luther's emphasis on faith alone. Erasmus therefore remained a member of the Catholic Church all his life. In relation to clerical abuses in the Church, Erasmus remained committed to reforming the Church from within. He also held to Catholic doctrines such as that of free will, which some Reformers rejected in favour of the doctrine of predestination. His middle road approach disappointed and even angered scholars in both camps.
