Catechism of the Catholic Church
False. Para. 472: This human soul that the Son of God assumed is endowed with a true human knowledge.
Para. 473: But at the same time, this truly human knowledge of God's Son expressed the divine life of his person (Cf. St. Gregory the Great, "Sicut aqua" ad Eulogium, Epist. Lib. 10, 39: PL 77, 1097 A ff.; DS 475). "The human nature of God's Son, not by itself but by its union with the Word, knew and showed forth in itself everything that pertains to God" (St. Maximus the Confessor, Qu. et dub. 66: PG 90, 840A).
