This is why God did not want the child to lose, because of the devil, anything that belonged to him; rather He allowed the child to have what was his by right. Therefore, He bestowed on him the devils’ art of knowing things that are done, said, and past—all this he knew. And Our Lord, who is all-knowing, knew, by the mother’s repentance, by her good confession, by the cleansing of confession, and by the true repentance he knew to be in her heart, that she had not wanted or willed what had
happened to her. By the power of the baptism with which the child was washed in the font, Our Lord willed that the sin of the mother should not harm him. And He also gave him the sense and the power to know the future.

This is the reason why he knew the things that were done, spoken, and past: he inherited this from the devil. Moreover, he knew things that were to come; Our Lord willed that he should know things contrary to those he knew from the other side. Now he could turn to whichever side he wanted, for if he wished, he could give the devils their due, or else His to God just as well.
