How can the church speak into a time of bitter partisan divisions? How can we be a redeeming presence in politics? How can the insights of John Calvin guide us even today? Dr. Matthew Tuininga, Professor of Moral Theology and the History of Christianity at Calvin Seminary, asked these questions in his new book, Calvin's Political Theology and the Public Engagement of the Church: Christ's Two Kingdoms (Law and Christianity). Tuininga spoke with Kevin den Dulk, the then director of the Henry Institute for the Study of Christianity and Politics at Calvin University. Let us listen in to that conversation.
