John Wesley: Biography, Achievements & Lasting Legacy

A key step in the development of Wesley's ministry was to travel widely and preach outdoors, embracing Arminian doctrines. Moving across Great Britain and Ireland, he helped form and organise small Christian groups that developed intensive and personal accountability, discipleship, and religious instruction. He appointed itinerant, unordained evangelists—both women and men—to care for these groups of people. Under Wesley's direction, Methodists became leaders in many social issues of the day, including the abolition of slavery and support for women preachers.

Although he was not a systematic theologian, Wesley argued against Calvinism and for the notion of Christian perfection, which he cited as the reason that he felt God "raised up" Methodists into existence. His evangelicalism, firmly grounded in sacramental theology, maintained that means of grace played a role in sanctification of the believer; however, he taught that it was by faith a believer was transformed into the likeness of Christ. He held that, in this life, Christians could achieve a state where the love of God "reigned supreme in their hearts", giving them not only outward but inward holiness. Wesley's teachings, collectively known as Wesleyan theology, continue to inform the doctrine of Methodist churches. In his early ministry years, Wesley was barred from preaching in many parish churches and the Methodists were persecuted; he later became widely respected, and by the end of his life, was described as "the best-loved man in England".
