3 For Jesus has been counted worthy of more glory than Moses—as much more glory as the builder of a house has more honor than the house itself. 4 (For every house is built by someone, but the builder of all things is God.) 5 Now Moses was faithful in all God's house as a servant, to testify to the things that were to be spoken later, 6 but Christ is faithful over God's house as a son (Heb 3:3-6).
Here's a subtle argument for the deity of Christ. On the one hand it sets up a comparison between God the Father and Christ. On the other hand it sets up a comparison and contrast between Moses and Christ.
It plays on different connotations of the "house" metaphor. At one level, the house is the world. The cosmos. The world is mankind's home. This is where we live. God made the house.
At another level, it connotes the "house of Israel". The passage is, in part, riffing off of Num 12:7 ("Not so with my servant Moses. He is faithful in all my house").
Although Moses was Israel's greatest prophet, Israel's paradigm prophet, he was just a member of Israel's household. Just a creature. Just a servant. Just a member of the family.
By contrast, Jesus is the Son. He stands "over" the Father's house. Jesus is to the builder as Moses is to the dweller. Yet the builder is divine.
Although we might think fidelity is a merely human virtue, Scripture also stresses divine fidelity as a divine virtue. To be faithful to God is commendable because God is faithful to his people.
