Jennings Ligon Duncan III is an American Presbyterian scholar and pastor. He is the current president of the Alliance of Confessing Evangelicals, a broad coalition of evangelical Christians from various denominations. It aims to call the church to repent of what it see as its worldliness, and to take up the mantle of the Protestant reformers in recovering the centrality of worship and doctrine in the life of the church. In his capacity as president, Duncan regularly speaks at the Philadelphia Conference on Reformed Theology, an Alliance-related forum that offers quarterly conferences on Reformed doctrine and history.[citation needed] He also contributes to the Alliance's online magazine and blog, Reformation 21
