Speak truth to power

St. Catherine of Siena in her exhortation to Pope Gregory:

You know that the devil is not cast out by the devil, but by virtue.

By the fragrance of their virtue they would help eliminate the vice and sin, the pride and filth that are rampant among the Christian people—especially among the prelates, pastors, and administrators of holy Church who have turned to eating and devouring souls, not converting them but devouring them! And it all comes from their selfish love for themselves, from which pride is born, and greed and avarice and spiritual and bodily impurity.
