In this episode of Christendom and the World Pastor Andrew Preus unpacks the heart of the Gospel and its connection to the Lord's Supper, with a focus on the often-misunderstood practice of closed communion. The conversation confronts the dangers of gospel reductionism, clarifies why doctrine cannot be reduced to a lowest-common-denominator message, and shows how bearing the cross is inseparable from the Christian life. Listeners will hear how the Lord's Supper proclaims Christ's death, why unity in confession is vital, and how the clarity of Scripture guards the church against error. At its core, the episode points to the ultimate goal of ministry: fostering assurance of salvation through the whole counsel of God, with Christ crucified at the center.
