Therefore, holy brothers and companions in a heavenly calling, consider Jesus, the apostle and high priest of our confession; He was faithful to the One who appointed Him, just as Moses was in all God’s household. For Jesus is considered worthy of more glory than Moses, just as the builder has more honor than the house. Now every house is built by someone, but the One who built everything is God. Moses was faithful as a servant in all God’s household, as a testimony to what would be said in the future. But Christ was faithful as a Son over His household. And we are that household if we hold on to the courage and the confidence of our hope. – Hebrews 3:1-6 (HCSB)
If we’re not careful, we have a tendency to swing back and forth between Subordinationism and Docetism. That is, we have a tendency to oscillate between treating Jesus like he’s only God, or like he’s only a Creature.
While it is a bit speculative, it seems as though our author recognized this propensity in his audience.
After demonstrating that Christ is God, then proceeding to demonstrate that Christ is man… he immediately reminds us that Christ is indeed God who became Man, so that he might bring us back to God.
After making propitiation for our sin, he becomes the apostle and high priest of our confession. That is, after coming to us to save us, he is sent back to the Father (apostle) and mediates (high priest) our confession to the Father. However, we must remember that although he is our servant, he is always and eternally our master.
Turning to another familiar example for his audience, he comments that just as Moses was faithful as one who was in God’s household (perhaps even more faithful than anyone else in God’s household), the Son was also faithful to the Father who sent him. And just as it was foretold in Deuteronomy, Jesus is a superior prophet to Moses, worthy of more glory and honor. While Moses was part of the house, the Father was the one who built the house.
This passage goes a long way to solidifying the idea that the Church is not a New Testament invention (pace Dispensationalism), rather than the Church is composed of the whole household of God throughout history.
While Moses was a faithful servant in the household that God built, Christ is a faithful heir to the Father’s riches, and reigns over that household as a faithful Son.
