Ordination of ministers

As the societies multiplied, they adopted the elements of an ecclesiastical system. The divide between Wesley and the Church of England widened. The question of division from the Church of England was urged by some of his preachers and societies, but most strenuously opposed by his brother Charles. Wesley refused to leave the Church of England, believing that Anglicanism was "with all her blemishes, nearer the Scriptural plans than any other in Europe". In 1745 Wesley wrote that he would make any concession which his conscience permitted, to live in peace with the clergy. He could not give up the doctrine of an inward and present salvation by faith itself; he would not stop preaching, nor dissolve the societies, nor end preaching by lay members. In the same year, in correspondence with a friend, he wrote that he believed it wrong to administer sacraments without having been ordained by a bishop.

When, in 1746, Wesley read Lord King 's account of the primitive church, he became convinced that apostolic succession could be transmitted through not only bishops, but also presbyters (priests). He wrote that he was "a scriptural episkopos as much as many men in England." Although he believed in apostolic succession, he also once called the idea of uninterrupted succession a "fable".

Edward Stillingfleet 's Irenicon led him to decide that ordination (and holy orders) could be valid when performed by a presbyter rather than a bishop. Nevertheless, some believe that Wesley was secretly consecrated a bishop in 1763 by Erasmus of Arcadia, and that Wesley could not openly announce his episcopal consecration without incurring the penalty of the Præmunire Act.

In 1784, he believed he could no longer wait for the Bishop of London to ordain someone for the American Methodists, who were without the sacraments after the American War of Independence. The Church of England had been disestablished in the United States, where it had been the state church in most of the southern colonies. The Church of England had not yet appointed a United States bishop to what would become the Protestant Episcopal Church in America. Wesley ordained Thomas Coke as superintendent of Methodists in the United States by the laying on of hands, although Coke was already a priest in the Church of England. He also ordained Richard Whatcoat and Thomas Vasey as presbyters; Whatcoat and Vasey sailed to America with Coke. Wesley intended that Coke and Francis Asbury (whom Coke ordained as superintendent by direction of Wesley) should ordain others in the newly founded Methodist Episcopal Church in the United States. In 1787, Coke and Asbury persuaded the American Methodists to refer to them as bishops rather than superintendents, overruling Wesley's objections to the change.

His brother, Charles, was alarmed by the ordinations and Wesley's evolving view of the matter. He begged Wesley to stop before he had "quite broken down the bridge" and not embitter his last moments on earth, nor "leave an indelible blot on our memory." Wesley replied that he had not separated from the church, nor did he intend to, but he must and would save as many souls as he could while alive, "without being careful about what may possibly be when I die." Although Wesley rejoiced that the Methodists in America were free, he advised his English followers to remain in the established church.
