Luke 2:50

They understood not. “Wist ye not?” Jesus had asked His parents, but “they understood not” His implied denial of Joseph and His affirmation of God as His Father. Mary “knew that He had disclaimed kinship to Joseph, and had declared His Sonship to God” (DA 82), but she did not grasp the full import of His words, particularly as they applied to His lifework. From this time forth His course of action was a mystery to His parents (DA 89). The word “they” here undoubtedly refers to Mary and Joseph. If even “they” understood not, the same would certainly be true of the doctors of the law and others present.
