St. Luke the Evangelist, inspired by the Holy Spirit, writes in Lk 2:52, “And Jesus advanced in wisdom and age and grace with God and men.” Now Jesus is Wisdom itself [1 Cor 1:24]: “But unto them that are called, both Jews and Greeks, Christ, the power of God and the wisdom of God;” cf. Jn 14:6: “Jesus saith to him: I am the way, and the truth, and the life. No man cometh to the Father, but by Me.“ But how could He Who is Wisdom itself increase in wisdom? It is not as if Christ increased in the habits of wisdom and grace, i.e., that He gained wisdom that He had not before. St. Luke means, according to the succinct explanation of St. Thomas Aquinas in ST III, q. 7, q. 12, ad 3, that Jesus advanced in wisdom as regard the effects, i.e., He did wiser and more perfect works as He aged; e.g. His first miracle was the changing of water into wine at the wedding of Cana, but later He worked the Transfiguration, Resurrection, and Ascension, which were much greater miracles.
