Where Jansenius and the Thomists agree on sufficient grace
Thesis LXXI. From all this it is easy to see how Jansenius's view agrees with the Thomists' and how it differs from theirs on the grace they call sufficient and the grace they call efficacious. As for the grace called sufficient, Jansenius grants with them that even those who are not converted and do not act well receive manifold grace from God, and that not only is their intellect enlightened but their will too is struck by various motions of grace.
Nor does he deny that, once such aids of grace are received, a person is truly said to be able to be converted and to act well. Conversely, the Thomists admit that all those who are not converted and do not act well lack an aid that is plainly necessary for anyone actually to be converted and act well.
Latin
LXXI. Ex quibus omnibus facile colligitur quomodo conveniat sententia Jansenii cum sententia Thomistarum, & quomodo ab illa discrepet, circa gratiam quam sufficientem, & circa eam quam efficacem vocant. Nempe, quod spectat gratiam quae sufficiens dicitur, Jansenius cum illis agnoscit eos ipsos qui non convertuntur, nec bene operantur, multiplicem a Deo gratiam accipere; & non solum eorum intellectum illuminari, sed & voluntatem variis gratiae motibus percelli: Nec diffitetur, acceptis ejusmodi gratiae auxiliis, hominem vere dici, posse converti, & bene operari. Et vice versa Thomistae fatentur omnibus illis qui non convertuntur, nec bene operantur, deesse auxilium quoddam plane necessarium ut quis actu convertatur & bene operetur.
