Stephen Grabill attempts the treacherous task of reintegrating Reformed Protestant theology with natural law by appealing to Reformation-era theologians such as John Calvin, Peter Martyr Vermigli, Johannes Althusius, and Francis Turretin, who carried over and refined the traditional understanding of this key doctrine. "Rediscovering the Natural Law in Reformed Theological Ethics" calls Christian ethicists, theologians, and laypersons to take another look at this vital element in the history of Christian ethical thought.
