Whether grace is fittingly divided into operating and cooperating grace?

Objections

Objection 1 : It would seem that grace is not fittingly divided into operating and cooperating grace. For grace is an accident, as stated above (Question [110], Article [2]). Now no accident can act upon its subject. Therefore no grace can be called operating.
Objection 2 : Further, if grace operates anything in us it assuredly brings about justification. But not only grace works this. For Augustine says, on Jn. 14:12, "the works that I do he also shall do," says (Serm. clxix): "He Who created thee without thyself, will not justify thee without thyself." Therefore no grace ought to be called simply operating.
Objection 3 : Further, to cooperate seems to pertain to the inferior agent, and not to the principal agent. But grace works in us more than free-will, according to Rm. 9:16: "It is not of him that willeth, nor of him that runneth, but of God that sheweth mercy." Therefore no grace ought to be called cooperating.
Objection 4 : Further, division ought to rest on opposition. But to operate and to cooperate are not opposed; for one and the same thing can both operate and cooperate. Therefore grace is not fittingly divided into operating and cooperating.
