In Fr. Paul Kramer’s quote below, he references the work of Fr. Francesco Bordoni titled “SACRUM TRIBUNAL IUDUCUM IN CAUSIS SANCTÆ FIDEI CONTRA HÆRETICOS ET HÆRESI SUSPECTOS“.
“Pertinacity consists in this, that one firmly consents in something or doubts, what he knows to be against faith, and determined by the Church. Thus, pertinacity is the voluntary consent of something, consciously or dubitatively against what one actually knows to be against faith. Thus it is deduced that heresy does not involve perseverance and permanence in the false assertion, since with the error being known the judgment can be made in an instant, such as one who knowingly wills something without a duration of time, therefore the will and the intellect can produce their acts in an instant, be they true and good, or false and evil – therefore also heresy.”
