The recent Thomists: efficacious grace really distinct from sufficient
Thesis XXV. Those called recent Thomists give the name sufficient grace to grace that confers the ability to act, even though, for a good action actually to follow, a fresh aid on God's part is still required beforehand. Efficacious grace, for them, does not merely confer the ability to act; of itself it effectively moves a person to act well, and so gives ability together with its effect.
On their view, therefore, efficacious grace is really distinct from sufficient grace in its being, since it adds to sufficient grace a further divine aid that must precede the good action and is needed for it.

XXV. Nam illi qui dicuntur Thomistae recentiores, sufficientem gratiam appellant illam quae dat posse operari, etiamsi ad hoc ut actu sequatur operatio bona, ex parte Dei novum auxilium praerequiratur: efficax vero gratia illis est, quae non simpliciter dat posse operari, sed per se & efficaciter hominem movet ad bene operandum, & sic dat posse cum effectu. Adeoque, juxta ipsos, gratia efficax, quoad entitatem, realiter distincta est a gratia sufficienti; quia, scilicet, gratia efficax sufficienti superaddit auxilium quoddam divinum ad bonam actionem praevium & necessarium.
