Never heard this version of the event? Even the most blessed of all mothers abused the very law Jesus came to free us from, seeking to enslave him to that law by characterizing him as immature, incomplete, and imperfect. The custodianship of parent over child as defined by law and tradition was meant for only a time and a season. When the child attained maturity, a date determined only by His Father in Heaven, the child is no longer counted the fruit of an Earthen Womb, but the child of Heaven. Looks like Jesus was counted as a Son in the eyes of God from the very womb and that though He was born of a woman under the law, He was always the Son of His Father in Heaven and subject only to His Father's Law of Perfect Liberty.
Just as they sought out to find and subdue their child, the young Jesus, in hopes of assuring His safe return to the place of subjection to them, they on this day insist on enforcing the same boundaries they set for Him then, on who He is NOW! It would be even more foolish now for them to attempt to subdue Him than it was back then when He was a child! But now they cleverly disguise their intent by playing the "He's Crazy!" card, hoping to legally gain custodianship over Him in that way. Just as He had the right to THEN act freely, as One under no law except that of His Heavenly Father, so too does He continue having that right today. Custody is a specific seizure of control that one legally exercises over another person. No human being has ever legally exercised control over another person in a universe where Jesus Christ is Lord.
So why do I write all this? Because Jesus is God's Message to us, because He reflects who we are in God's eyes. In Him, we see ourselves in the Spirit. Next time the world tries to bait you into coming under it's custodianship, know that custodianship is an exercise of immediate charge, as over a ward or a suspect, also translated as "safekeeping." Remember, You are already under God's safekeeping, the safe-keeping of the Good Shepherd... who gives His life for His sheep and the Father who gives His Life to His children. You don't need the so called "safe-keeping" wielded by the law, which is merely the legal right to take care of a needy child (such as a child whose parents are divorced). You're no needy children, God said, "You are Gods! All of you Sons of the Most High!" Because you are already under the care of The One whose child you indeed are, to be under another's safe-keeping would be like being kept in a prison or a jail! There's only one being in the universe with the right to call Himself the Warden of any prison-cell containing a Son of God, God The Father Himself.
