Same working, different essence: Jansenius and the Thomists part
Thesis XLVI. Jansenius and the recent Thomists agree that the grace of Christ by which people are converted and do good is grace efficacious of itself, which brings free choice under itself and is in no way subject to it, and which does not wait for the human will's consent for its effect to follow but brings that consent about infallibly and powerfully.
Yet they disagree about the nature and substance of that grace, and do not explain in the same way what it consists in and where it lies. For both, the way this grace works is the same; what it is differs.
Latin
XLVI. Caeterum quanquam Jansenius & Thomistae recentiores in eo conveniunt quod gratia Christi, per quam homines convertuntur & bene operantur, sit gratia per se efficax, quae liberum sibi subjicit arbitrium, nequaquam vero libero arbitrio subdita est; & quae, ut effectus illius sequatur, voluntatis humanae consensum non expectat, sed consensum illum infallibiliter & potenter efficit: inter se tamen dissentiunt de gratiae illius natura atque substantia: nec eodem modo explicant qua in re consistat atque posita sit. Utrisque gratiae istius modus operandi idem est, diversa vero illius essentia.
