The rise of atheism in modern Western societies is often treated as a rejection of religion—but what if this cultural trend is more accurately understood as part of Protestantism itself? In this live lecture, John Hamer of Toronto Centre Place explores how Protestant reforms—especially the rejection of Catholic tradition, the doctrine of sola scriptura, the emphasis on rational inquiry, and the rise of literalist interpretations of scripture—created fertile ground for natural religion and Enlightenment-era deism, and ultimately for an ethical framework devoid of spiritual or supernatural elements. We will also consider how modern atheism continues to engage in dialogue with Evangelicalism—another modern expression of Protestantism—echoing the way theologically opposing movements have remained in conversation throughout Christian history.
