Wesleyan theology, otherwise known as Wesleyan–Arminian theology, or Methodist theology, is a theological tradition in Protestant Christianity that emphasizes the "methods" of the eighteenth-century evangelical reformers John Wesley and his brother Charles Wesley. More broadly, it refers to the theological system inferred from the various sermons, theological treatises, letters, journals, diaries, hymns, and other spiritual writings of the Wesleys and their contemporary coadjutors such as John William Fletcher.
