Rushdoony’s Sermons in First and Second Corinthians are the last of his Biblical commentaries—delivered shortly before his passing—but it represents a fitting close to his teaching ministry. He said Paul’s letters are difficult to preach on because they speak to the sins of Christians, and with the church at Corinth, the long list of sins included division, strife, injustice, immorality, doctrinal error, and the abuse of the sacraments.

Despite their many transgressions, the apostle Paul still addresses the believers at Corinth as saints and referred to their gathered community as the church of the Lord Jesus Christ. They were still Christ’s embassy on earth. They could still develop into a greater training center for Christian action.

This is why Paul’s letters to the Corinthians are relevant to the church today, and it’s also why Rushdoony’s sermons on these two epistles are invaluable to us now. Rushdoony was criticized for his ecclesiology, but only because he always saw the greater fact of God’s advancing Kingdom, and the church as the equipping center for the saints. Rushdoony’s fresh application of Paul’s warnings and admonitions will help Christians, pastors, and churches to free themselves of the same sins and return to the church as an embassy of the Kingdom.
