Why is understanding heresies important for Christians?

Understanding heresies is vital for Christians as it allows believers to discern truth from error. The Reformed tradition teaches that the church must be vigilant against false teachings that distort the purity of the gospel. Waves of apostasy, as mentioned in historical contexts, remind us that deviation from biblical teaching often arises subtly, leading many astray. Engaging with historical heresies helps Christians grasp the importance of sound doctrine, enabling them to better articulate and defend their faith in the face of challenges. It also fosters a deeper appreciation for the truths recovered during the Reformation, pulling the church back toward foundational biblical tenets that affirm God's sovereignty and grace.
