This book explores the life, work, and theological contributions of Charles Hodge (1797-1878), one of the most influential American Reformed theologians of the 19th century. Through an in-depth analysis of his biography, intellectual development, and theological writings, the book provides a comprehensive understanding of Hodge's role in shaping Reformed thought, American Presbyterianism, and broader evangelical theology. The text highlights Hodge's defense of biblical inerrancy, his systematic approach to theology, and his emphasis on the sovereignty of God in salvation, all of which were foundational to his theological legacy. The book traces Hodge's work at Princeton Theological Seminary, examining how his teaching, writings, and leadership helped establish the institution as a central hub for Reformed theological education and intellectual engagement in the United States. It also delves into the controversies and theological opposition Hodge faced during his career, including his critiques of revivalism, liberalism, and the social gospel. The text reflects on the enduring impact of Hodge's theological principles on contemporary Reformed and evangelical thought, examining their influence in the 20th and 21st centuries, particularly in relation to biblical authority, salvation, and the role of the church in society. Through a detailed exploration of his personal, pastoral, and academic life, the book reveals how Hodge's legacy continues to shape theological education, ecclesial practice, and Christian witness today.
