Commentators universally explain that Paul was “grieved” not by the content of the woman's message, but by its demonic source. Accepting a truthful testimony from an evil spirit would create a dangerous association, suggesting the gospel was in league with demonic powers. As scholars like Spurgeon and Calvin note, this would confuse the public and damage the credibility of the gospel. Paul's action demonstrates that God’s truth does not need or want endorsement from unholy sources.
