Whether grace is fittingly divided into prevenient and subsequent grace?

Objections

Objection 1 : It would seem that grace is not fittingly divided into prevenient and subsequent. For grace is an effect of the Divine love. But God's love is never subsequent, but always prevenient, according to 1 Jn. 4:10: "Not as though we had loved God, but because He hath first loved us." Therefore grace ought not to be divided into prevenient and subsequent.
Objection 2 : Further, there is but one sanctifying grace in man, since it is sufficient, according to 2 Cor. 12:9: "My grace is sufficient for thee." But the same thing cannot be before and after. Therefore grace is not fittingly divided into prevenient and subsequent.
Objection 3 : Further, grace is known by its effects. Now there are an infinite number of effects---one preceding another. Hence it with regard to these, grace must be divided into prevenient and subsequent, it would seem that there are infinite species of grace. Now no art takes note of the infinite in number. Hence grace is not fittingly divided into prevenient and subsequent.
