Critique and Reception

While Duncan's work is highly respected within Reformed and evangelical communities, his focus on confessional and covenant theology means that his publications are largely situated within those contexts rather than mainstream academic venues. Critics may point to the confessional nature of his work as limiting its cross-denominational appeal. Nonetheless, Duncan is valued for his clear articulation of Reformed theology and his ability to communicate complex theological concepts to a broad audience.
