I answer that, The justification of the ungodly is brought about by God moving man to justice.  For He it is “that justifieth the ungodly” according to Rom. 4:5.  Now God moves everything in its own manner, just as we see that in natural things, what is heavy and what is light are moved differently, on account of their diverse natures.  Hence He moves man to justice according to the condition of his human nature.  But it is man’s proper nature to have free-will.  Hence in him who has the use of reason, God’s motion to justice does not take place without a movement of the free-will; but He so infuses the gift of justifying grace that at the same time He moves the free-will to accept the gift of grace, in such as are capable of being moved thus.

Reply Obj. 1:  Infants are not capable of the movement of their free-will; hence it is by the mere infusion of their souls that God moves them to justice.  Now this cannot be brought about without a sacrament; because as original sin, from which they are justified, does not come to them from their own will, but by carnal generation, so also is grace given them by Christ through spiritual regeneration.  And the same reason holds good with madmen and idiots that have never had the use of their free-will.  But in the case of one who has had the use of his free-will and afterwards has lost it either through sickness or sleep, he does not obtain justifying grace by the exterior rite of Baptism, or of any other sacrament, unless he intended to make use of this sacrament, and this can only be by the use of his free-will.  And it was in this way that he of whom Augustine speaks was regenerated, because both previously and afterwards he assented to the Baptism.

Reply Obj. 2:  Solomon neither merited nor received wisdom whilst asleep; but it was declared to him in his sleep that on account of his previous desire wisdom would be infused into him by God.  Hence it is said in his person (Wis. 7:7):  “I wished, and understanding was given unto me.”

Or it may be said that his sleep was not natural, but was the sleep of prophecy, according to Num. 12:6:  “If there be among you a prophet of the Lord, I will appear to him in a vision, or I will speak to him in a dream.”  In such cases the use of free-will remains.

And yet it must be observed that the comparison between the gift of wisdom and the gift of justifying grace does not hold.  For the gift of justifying grace especially ordains a man to good, which is the object of the will; and hence a man is moved to it by a movement of the will which is a movement of free-will.  But wisdom perfects the intellect which precedes the will; hence without any complete movement of the free-will, the intellect can be enlightened with the gift of wisdom, even as we see that things are revealed to men in sleep, according to Job 33:15, 16:  “When deep sleep falleth upon men and they are sleeping in their beds, then He openeth the ears of men, and teaching, instructeth them in what they are to learn.”
