|James Tissot, Jesus Found in the Temple (1890)|
The point of the occult, of every bit of black magic throughout every age of history, has been fixated on one thing: bending the supernatural or Divine to our wills. Instead of obeying God, the occult seeks to make God obey us (or, barring that, settling for working with one of His fallen angels). Yet Jesus Christ takes the initiative, and gives this most coveted authority to a poor Jewish couple. If this weren't explicitly in Scripture, can there be any doubt that Protestants would accuse Catholics of idolatry for believing this about Mary and Joseph?
This affirms that Mary and Joseph are true parents to Jesus Christ, as shocking and upsetting as that might be. There is a tendency amongst some Protestants to reduce them to something much less: to treat Mary like some sort of human mason jar that happened to hold the Christ, but who can be discarded after Christmas along with the tree, or to treat Joseph like an imposter. A Protestant reader actually accused Mary of being a liar for calling Joseph Jesus' father (Lk. 2:48), yet that's exactly what Scripture says of him (Lk. 2:41). True, he's not Jesus' biological father, but that's how adoption works. And since all of us are adopted (since Christ is the only-begotten Son, as John 3:16 says), who are we to complain?
And the timing of this verse is significant. It comes just two verses after Jesus says to His parents (Lk. 2:49), “Did you not know that I must be in my Father’s house?”
That is, Jesus doesn't trade obedience to God the Father for obedience to Mary and Joseph. Rather, in obeying His parents, He is obeying the Father; and in obeying the Father, He is obeying His parents (since this is their greatest desire for Him). There's no tension or competition between the two. The Father isn't jealous of Joseph for doing the very thing He placed him on earth to do, for example. Loving and honoring Mary and Joseph isn't somehow contrary to loving and honoring the Father.
So we, who are adopted into the Holy Family by virtue of our Divine adoption (cf. Ephesians 1:5), must follow our Lord's example. Love, honor, and obey Mary and Joseph with abandon, with the knowledge that you are doing the will of God, and following the example of Jesus Christ.
