Catena Aurea on Luke 3:21–22: Gregory the Great

Or else, Every one who by repentance corrects any of his actions, by that very repentance shews that he has displeased himself, seeing he amends what he has done. And since the Omnipotent Father spoke of sinners after the manner of men, saying, It repents me that I have made man, (Gen. 6:7.) He (so to speak) displeased Himself in the sinners whom He had created. But in Christ alone He pleased Himself, for in Him alone He found no fault that He should blame Himself, as it were, by repentance.
