This presentation, titled "From Augustine to Wesley: Protestant Roots" by Dwayne Tutt, explores the historical and theological evolution of Christian preaching by examining the legacies of four pivotal figures. It begins with Augustine, who established foundational Western doctrines like original sin and divine grace, and moves through Martin Luther’s Reformation challenge against church corruption, which emphasized salvation through faith and the authority of Scripture. The document then contrasts John Calvin’s focus on God’s absolute sovereignty and predestination with John Wesley’s emphasis on free will, sanctification, and practical holiness. Ultimately, the text argues that understanding this theological lineage equips modern preachers with the doctrinal clarity, courage, and compassion necessary to lead impactful and purposeful ministries today.
