Hebrews 8:10 makes it abundantly clear that the Old Testament case law applies in the New and Better covenant.
7 For if that first covenant had been faultless, then no place would have been sought for a second. 8 Because finding fault with them, He says: “Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and with the house of Judah— 9 not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they did not continue in My covenant, and I disregarded them, says the LORD. 10 For this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people. 11 None of them shall teach his neighbor, and none his brother, saying, ‘Know the LORD,’ for all shall know Me, from the least of them to the greatest of them. 12 For I will be merciful to their unrighteousness, and their sins and their lawless deeds[b] I will remember no more.”13 In that He says, “A new covenant, ” He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
While it is true that 7:12 teaches the explicit change in the law,
11 Therefore, if perfection were through the Levitical priesthood (for under it the people received the law), what further need was there that another priest should rise according to the order of Melchizedek, and not be called according to the order of Aaron? 12 For the priesthood being changed, of necessity there is also a change of the law. 13 For He of whom these things are spoken belongs to another tribe, from which no man has officiated at the altar.
one must ask what exactly the explicit change is given that 8:10 clearly teaches that the OT law remains valid since it is that law which is to be written on the hearts and etched in the minds of the New Covenant people.
10 For this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people.
I would contend that given the explicit statement that the new and better covenant includes the OT law put in minds and written in hearts the explicit change that 7:12 is referring to is the explicit change that comes with the fulfillment of the ceremonial law. Such an interpretation does justice to Hebrews since the danger that the author of Hebrews is dealing with is the danger of the Jews, to whom he is writing, going back to the Old Covenant ceremonial system. The danger in Hebrews is not the danger of the recipients of the letter applying the OT moral and case law. That is not what the book of Hebrews is about. In Hebrews the danger is that people are inching towards going back to the ceremonial shadows. And so the writer to the Hebrews tells them that the Levitical Priesthood which officiates those ceremonies and the ceremonial law is past. That is the explicit change in the law that is being spoken of. Indeed the context demands that reading in vs. 10-11.
The context of 7:10-11 is the ceremonial law and the Levitical Priesthood — not the moral or civil law as those aspects of the law will be now written on their hearts and put in their minds of those of us in the New Covenant.
Indeed, to appeal to 7:10-11 as proof that the Old Testament law is done away with actually proves to much for such a sweeping change would have to apply to the Moral law as well so that, if we were to be consistent, would have to say that the Moral law (the Ten Commandments) no longer apply. I know of no Reformed theologians who have ever suggested such a thing.
So the new and better covenant that is promised in Hebrews chapter 8 is a new and better covenant because it is the fulfillment of all that the old and worst covenant anticipated. The old covenant is set aside in the sense that when the reality comes the shadows are no longer present but in as much it is the fulfillment of the Old Covenant it brings to the fore all that the Old Covenant promised. The thing to keep in mind is that they are not two antithetical covenants but a covenant of promise and covenant of fulfillment. Try to think of the relationship between the two covenants like the relationship between a engagement promise and a wedding promise. When the wedding promise comes the engagement promise is fulfilled and set aside and only inasmuch as it is taken up into the new and better wedding promise. The two promises though distinct are clearly related and even though the former engagement promise is put off it is putt off by being incorporated into the wedding promise which it anticipated.
I think that John Gill has a most helpful explanation of Hebrews 8:7 (and I’m not Baptist; I’m Presbyterian 🙂
Just check his commentary.
Original: The two promises though distinct are clearly related and even though the former engagement promise IS PUT OFF IT IS PUTT OFF by being incorporated into the wedding promise which it anticipated.
Edit: Remove “it is putt off”
