John Wesley (28 June [O.S. 17 June] 1703 - 2 March 1791) was an Anglican cleric and Christian theologian. Wesley is largely credited, along with his brother Charles Wesley, with founding the English Methodist movement which began when he took to open-air preaching in a similar manner to George Whitefield. In contrast to George Whitefield's Calvinism (which later led to the forming of the Calvinistic Methodists), Wesley embraced Arminianism. Methodism in both forms was a highly successful evangelical movement in the United Kingdom, which encouraged people to experience Jesus Christ personally.
