Sam Hamstra Jr. is the Affiliate Professor of Church History and Worship at Northern Seminary. He is the editor of several studies, most recently The Reformed Pastor: Lectures on Pastoral Theology by John Williamson Nevin, and has authored several works on worship, including What's Love Got to Do With It? How the Heart of God Shapes Worship.
John Williamson Nevin (1803-1886), was a professor successively at Western Theological Seminary, the Theological Seminary of the German Reformed Church at Mercersburg, and Franklin and Marshall College. He was a leading nineteenth-century theologian and founding editor of Mercersburg Review.

John Nevin's vision of the church as ""one, holy, catholic, and apostolic"" grew out of his critique of the revivalism and sectarianism that prevailed throughout evangelical Christianity in the nineteenth century. He deepens his perception of catholicity as an expression of Christian wholeness, his response to the parochialism that ruled American religion and life. He grounds congregational life and mission in the Lordship of Jesus Christ, ordered by the whole Christian tradition, which comes into focus in the Apostles' Creed. This edition carefully preserves the original texts while providing extensive introductions, annotations, and bibliography to both orient the reader and to facilitate further scholarship.
The Mercersburg Theology Study Series presents for the first time attractive, readable, scholarly modern editions of the key writings of the nineteenth-century movement known as the Mercersburg Theology. An ambitious multi-year project, it aims to make an important contribution to the academic community and to the broader public, who can at last be properly introduced to this unique blend of American and European Reformed and Catholic theology.
""Nevin's understanding of the mission of the church is as counter-cultural and relevant today as in the nineteenth century. By making Nevin accessible, Sam Hamstra offers church leaders a thoughtful, provocative dialogue partner to imagine faithful ministry today.""
