Thesis CXVIII. Peter of Saint Joseph teaches this in his theological treatise on divine grace, disputation 6, section 6, where his first assertion reads: 'It is certain from faith that some grace sufficient for salvation is given, a grace by which a person can be converted even though he is not actually converted.' His second is this: 'That grace is called sufficient which is enough not only for a person to be able to act, but also for him actually to act if he chooses.'

CXVIII. Id docet Petrus ille a Sancto Joseph in tractatu Theologico de gratia Divina Disputatione 6. Sectione 6. Ubi haec est ejus prima assertio. Certum est ex fide dari gratiam aliquam sufficientem ad salutem, qua scilicet homo converti possit, licet actu non convertatur. Secunda vero sic se habet. Ea gratia dicitur sufficiens, quae sufficit non tantum ut homo operari possit, sed etiam ut actu operetur si velit.
