John Wesley (1703–1791) was a seminal English cleric, theologian, and evangelist who is best recognized as a founding figure of the Methodist movement. His writings and sermons played a pivotal role in the development of Methodist theology, particularly concerning Christian practice and discipleship. One of his most significant works, 'A Plain Account of Christian Perfection' (1766), offers an exhaustive exposition on the doctrine of Christian perfection, a cornerstone concept in Methodist theology. In this treatise, Wesley delves into the attainability of spiritual completeness in this life, rigorously examining the Scriptures and early Church teachings to affirm his views (Wesley, J. (1766). A Plain Account of Christian Perfection). Wesley's literary style combines methodical argumentation with fervent religiosity, reflecting both his Oxford education and pietistic influences. His writings contributed extensively to religious literature and shaped the Methodist approach to sanctification and holy living. Wesley's legacy endures through his published sermons, hymns, and theological treatises, which continue to influence Christian thought and practice.
