Desiderius Erasmus of Rotterdam was a famous philosopher/humanist who developed the "Philosophy of Christ". It was a book that was directed at the "common man" who needed spiritual guidance. Erasmus defines the Christian life as a war against the temptations of the world. A Christian needs to rely on the knowledge of the Bible and prayer to conquer the fight against worldly temptations.
