@SC, we believe that Christ, the person, was fully God and fully man. God in the bush was God in a bush; the bush was not God, but only contained God. On the other hand, Christ WAS (and IS) God, as well as being a person.
This is, of course, very unintuitive and hard to really grasp, much like the Trinity itself, but anyway, that doctrine is the reason for our worshiping Christ.
Also, the first commandment does not say "The Father," as I'm sure you're aware.
Regards.
