One question though. If the resurrected saints are to be rulers and priests under Christ, how does that fit in with a Leviticus priesthood during the millennium?
The book of Hebrews, does it not talk about the Leviticus priesthood being replaced by the Melchizedek priesthood?
Yes Paul was writing in Hebrews to tell them about the NT priesthood in real terms compared to the Levitical priesthood. He knew the Temple and old Priesthood was coming to an end in 70 A.D. - well every soon, he may not have known the exact year. He was telling them that the now NT priesthood was far superior to the physical temple priesthood, and so they had to get their mind in MORE full gear about the Messiah's priesthood. Remember as I brought out, there were Jews in the church that were zealous for the whole law of Moses, their mind was actually still too much on the laws of Moses with circumcision and Temple rites. Not wrong to do while the Temple stood, as Paul went ahead and did some of it, though it meant nothing as far as salvation was concerned. But those Jews in the church needed some pretty straight talk about the OLD stuff superseded by the NEW which WAS GREATER BY FAR, and the Old was soon going to be fully gone in this age.
So it was back then as it will be in the context of the Temple in Jerusalem..... but they only had the OLD with the NEW for 40 years, from 30 A.D. to 70 A.D. In the age to come that part of the Old will be with the New for 1,000 years!
So there will be a physical outward Old in the Temple at Jerusalem in the age to come, which will have the MUCH GREATER NEW, OVER ALL OF THAT which is Old.
THE TEMPLE and rites in the age to come will be all PHYSICAL stuff for a PHYSICAL people of Israel during that 1,000 years.
THAT WILL BE PHYSICAL, AND NO BEARING ON THE NEW SPIRITUAL, but for lessons to learn from it, as we learn a lesson from physical water baptism.
OVER ALL that physical, will be the greater Melchizedek Priesthood..... the greater SPIRITUAL ..... over....well everything. Christ will still be "THE" High Priest, all under Him....us, we will still be part of His greater Spiritual Priesthood.
Okay, David is to be over Israel; the 12 apostles will rule a tribe of Israel, that is written clearly for us, in the Gospels and Prophets. But they will STILL be ministers or priests for the SPIRITUAL side of things for salvation!
We shall rule over towns, villages, cities, us saints in the Kingdom. We shall be in charge of certain physical things going on in a still physical world of 1,000 years. BUT we shall be priests in the Messiah's Melchizedek priesthood, for all spiritual matters.
So you have to look at it like it was for 40 years of the first 40 years of the New Testament Christ priesthood; the Old still continued for 40 years ALONGSIDE the greater NEW Covenant Melchizedek priesthood.
The difference for the physical people, will be that in the age to come, all the physical people will see and know clearly the difference, between that which is taking place in a literal Temple with old literal rites of that Temple, and what IS THE GREATER ` spiritual Priesthood for salvation and all things spiritual.
It was slightly still somewhat obscure for some Jews in the Church of God, zealous for all the laws of Moses, so Paul had to write to the Hebrews and try very plainly to set the record straight...to get them to see certain Old rites were not anywhere close to being as great as the NEW ones that came in at the beginning of the NEW Testament church, and the Old was soon to vanish away in this present age.
Now the Gentiles had no problem, they were told they did not HAVE to do any Temple rites, they were not as INGRAINED with Temple rites as were the Hebrews; they could see it all much clearer than Jews in the Church of God, born into, and brought up, with Temple rites.
So think of it as A LITTLE BIT of the OLD [Temple rites] ALONGSIDE the massive GREATER SPIRITUAL salvation Melchizedek Priesthood, as somewhat like it was for 40 years before..... in the first century from 30 A.D. to 70 A.D. During that 40 years you had the Old still operating in the Temple, while the New was also in effect. Both the Old and the New was from God, but the NEW was much MUCH greater than the Old, based upon greater and better promises of SPIRITUAL SALVATION through the greatest HIGH priest of history - Christ Jesus.
