What Is the Core Question of the Reformation?

Dr. Michael Reeves invites listeners to examine the question that drove the Reformers: how should we understand sin? The answer he presents is not a simple yes or no, but a tension between two ways of seeing sin’s depth.

Shallow Optimism vs. Deep Bondage

Reeves contrasts the views of Martin Luther and Desiderius Erasmus. Luther, after years of monastic practice, came to see sin as a weight that “dragged us to hell,” a deep, heart‑level bondage that cannot be overcome by human effort. Erasmus, on the other hand, treated sin more like a lack of discipline—a problem that could be corrected through personal diligence and moral reform.

How the Debate Shapes the Gospel

When sin is viewed as a deep bondage, the need for divine grace becomes unavoidable. Luther’s insistence that “we do not become righteous by doing righteous deeds” points to a gospel that depends on God’s work in the heart. Erasmus’s perspective, which emphasizes human effort, leads to a different picture of how the church should function and how believers should pursue holiness.

Implications for the Church Today

Reeves shows that the two perspectives produce distinct visions of the church: one that resembles an army disciplined by duty, the other that resembles a family bound by love for God. The choice between these models affects how the church addresses sin, encourages believers, and understands the role of grace.
