Herein the second objection to the Thomistic distinction between gratia efficax and gratia sufficiens is already indicated.

Now if we carry these philosophical principles from the domain of the natural to the supernatural, then efficacious grace (gratia efficax) must be regarded as a physical premotion of the supernaturally equipped will to the performance of a good act, for revelation undeniably refers back to grace not only the possibility, but also the willing and the actual performance of a good act.

The necessity of gratia efficax does not spring from the subordinate relation between causa prima and causa secunda, but from the inherited perversity of fallen human nature, whose evil inclinations can no longer, as once in Paradise, be overcome by the converting grace (gratia versatilis; adjutorium sine quo non), but only by the intrinsically efficacious heavenly delight (gratia efficax; adjutorium quo).

The Catholic Encyclopedia, Volume 6: Fathers of the Church-Gregory XI 1840-1916 1913

Now since one and the same grace may in one instance be efficacious, and in another inefficacious, it follows that the so-called gratia efficax must be conceived according to its essence as efficax ab extrinsico.

The second characteristic difference between the two systems of grace lies in the radically different conception of the nature of merely sufficient grace (gratia sufficiens) and of efficacious grace (gratia efficax).

Thomism derives the infallible success of efficacious grace from the very nature of this grace, and assumes consequently the grace to be efficacious intrinsically (gratia efficax ab intrinseco), Molinism ascribes the efficacy of grace to the free co-operation of the will and consequently admits a grace which is merely extrinsically efficacious (gratia efficax ab extrinseco).

The Catholic Encyclopedia, Volume 10: Mass Music-Newman 1840-1916 1913

Here gratia efficax is intrinsically and by its nature (ab intrinseco s. per se) efficacious, and consequently intrinsically and extrinsically different from sufficient grace (gratia sufficiens), which imparts only the posse, not the agere.

The Catholic Encyclopedia, Volume 6: Fathers of the Church-Gregory XI 1840-1916 1913

The question which both schools set themselves to answer is this: Whence does efficacious grace (gratia efficax), which includes in its very concept the actual free consent of the will, derive its infallible effect; and how is it that, in spite of the infallible efficacy of grace, the freedom of the will is not impaired?

The Catholic Encyclopedia, Volume 10: Mass Music-Newman 1840-1916 1913

A second pair of graces important for the understanding of the controversies on grace is that of efficacious and merely sufficient grace (gratia efficax et mere sufficiens).
