“Christ must be preached wholly and only. We must not take anything from Christ, nor join anything to Christ.

The Galatians did but believe the necessity of ceremonies with Christ; and the apostle tells them, ‘Ye are fallen from Christ,’ Galatians 5:4. It is a destructive addition, to add anything to Christ.

Away with other satisfaction. The satisfaction of Christ is enough.

Away with merits. The merits of Christ are all-sufficient.

Away with merit of works in matter of salvation. Christ’s righteousness is that that we must labour to be found in, and ‘not in our own,’ Philippians 3:9. All is but ‘dung and dross,’ Philippians 3:8, in comparison of the excellent righteousness we have in Jesus Christ.

You must hear, and we must preach all Christ and only Christ. St Paul saith, he was ‘jealous with a holy jealousy’ over those he ‘taught.’ Why? ‘Lest Satan should beguile them, and draw them from Christ,’ to any other thing, 2 Corinthians 11:2. Why is the Church of Rome so erroneous, but because she leaves Christ and cleaves to other things?

Therefore we must labour to keep chaste souls to Christ, and those that are true preachers, and ambassadors, and messengers, they must be ‘jealous with a holy jealousy’ over the people of God, that they look to nothing but Christ.”
