Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 2:51-52

“Not that He became wise by making progress, but that by degrees He revealed His wisdom. As it was when He disputed with the Scribes, asking them questions of their law to the astonishment of all who heard Him. You see then how He increased in wisdom, in that He became known to many, and caused them to wonder, for the shewing forth of His wisdom is His increase. But mark how the Evangelist, having interpreted what it is to increase in wisdom, adds, and in stature, declaring thereby that an increase or growth in age is an increase in wisdom.”
