In Hebrews 3, we read that Christ is superior to Moses. Also in Hebrews, we read that Christ is superior to Aaron. Now, Aaron represented the priesthood. Christ isn't after the old priesthood, he is after a different priesthood, one that is eternal. Aaron's priesthood has its authority from the Mosaic Law. Now, Moses represented the prophet position. Christ is greater than Moses. This would mean that the revelation that came from Christ was superior to that of Moses. This would mean that Christ's law is superior to that of Moses. Covenant theologs maintain that Christ only kept Moses' law, but he didn't bring in his own law. This makes the whole comparison moot and meaningless. Hebrews is replete with statements about Christ being superior than... It even says that it is a better covenant built upon better promises. Yet Covenant theologs ignore this by saying it is just a different administration. Christ is not a steward of Moses, he is the new law giver. Just as he is better than Aaron and his priesthood, he is better than Moses and his role as prophet.
