Jansenius and his disciples: only supernatural grace and Christian faith make a work morally good
It is above all Jansenius and his disciples who embrace this last view. They all hold that grace is needed for a morally good work, and not just any grace: it must be grace of the supernatural order, through which faith is first created in men. Nor is it faith of any sort, but Christian and infused faith, which out of devout affection we give to God speaking in his word.
They will have every good volition begin from faith of this kind, without which no good work can exist. So all the works not only of Gentiles but of everyone who lacks faith in Christ, such as heretics, are true and mere sins, however praiseworthy and good they look to men.
Latin
XXXIII. Praesertim vero postremam hanc sententiam amplectuntur Jansenius & ejus Discipuli. Sentiunt enim omnes illi ad bonum opus morale necessariam esse gratiam, non quamlibet, sed quae sit ordinis supernaturalis, & per quam primo creatur in hominibus fides; neque haec qualiscunque, sed Christiana & infusa, quam ex pio affectu, Deo in verbo suo loquenti adhibemus. Ab ejusmodi fide incipere volunt omnem bonam volitionem, sine qua impossibile est esse aliquod bonum opus. Adeo ut opera omnia, non tantum Gentilium, sed omnium qui fide in Christum destituti sunt, quales sunt haeretici, vera & mera peccata sint, utcunque hominibus laudabilia & bona appareant.
