Trent on Assurance

The Tridentine Decree on Justification uses the word fiducia only in neg- ative terms. Chapter 9 is headed “Against the Vain Confidence of Heretics” (Contra inanem hæreticorum fiduciam). This states: "Yet it should not be said that sins are forgiven, or ever have been forgiven, to those who boast of their confidence (fiduciam) in and certainty of the remission of their sins and rest on that alone. For this vain and ungodly confidence (fiducia) may exist (and in our day does exist) among heretics and schismatics and is preached with great vehemence in opposition to the Catholic Church."
