I have to start a thread on this wrong "alignment".
I don't see a thread and I'm about to leave town for a long weekend, so I will respond to this here based upon an "assumption" of what your argument will be from past conversations. So if I'm wrong and there's some new evidence to present, forgive me and I'll check it out late Monday.
The alignment I present is the one that Scripture presents. God makes Israel a kingdom of priests in Exodus 19 "5 Now therefore, if you will obey my voice and keep my covenant, you shall be my own possession among all peoples; for all the earth is mine, 6
and you shall be to me a kingdom of priests and a holy nation. These are the words which you shall speak to the children of Israel."
I'm assuming you will try to make the argument that God revokes the priesthood of the nation from Israel and gives it to the Levites because in Exodus 20, "18 Now when all the people perceived the thunderings and the lightnings and the sound of the trumpet and the mountain smoking, the people were afraid and trembled; and they stood afar off, 19 and said to Moses, "You speak to us, and we will hear; but let not God speak to us, lest we die."
The theory that God promises Israel they will be to him a kingdom of priests and then revokes it because they want to hear God through Moses falls completely flat for many reasons:
1) Nowhere in Scripture does God revoke or even indicate he is revoking the priesthood of the nation from Israel -- prove me wrong on that
2) When Moses receives the instructions for the Levitical priesthood from God, nowhere does God indicate this is being put in place of the priesthood of the nation.
3) The role of the Levitical priesthood is not defined as "hearing" God for the people. Moses was in this role yes, but Joshua who succeeds him is neither a Levite or a priest. The role of "hearing" God for the people falls to the prophets, many of whom are neither Levites or priests.
4) This calling of God to the people of Israel to be a kingdom of priests coincides with his call to "be my own possession among all peoples", the 'chosen' people. This call is not revoked by God.
5) In 1 Peter 2:9 when Peter tells us that we are a "chosen race, a royal priesthood, a holy nation, God's own people", he quotes Exodus 19 and God making Israel a nation of priests, directly aligning the priesthood of the believers with the priesthood of the nation of Israel, not the priesthood of the Levites. Nowhere does he use the opportunity to align the NT priesthood of the believers with that of the OT Levitical priesthood.
The theory that because Israel asks to not hear God directly he somehow revokes the priesthood of the nation from them and puts the Levites in their place is not supported by Scripture. It arises from a need to make the NT priesthood of the nations align and therefore fulfill the Levitical priesthood in order to fit a desired NT model where there is no separate ministerial priesthood. It starts with a conclusion and tries to backfill into it. The concept that there is a not a separate ministerial priesthood in the NT is flatly shown to be false by Paul in Romans 15 when he says:
15 But on some points I have written to you very boldly by way of reminder, because of the grace given me by God 16 to be a minister of Christ Jesus to the Gentiles
in the priestly service of the gospel of God, so that the offering of the Gentiles may be acceptable, sanctified by the Holy Spirit. (RSV)
If the only priesthood in the NT (aside from Christ as high priest) is the priesthood of believers, Paul's statement about his role as 'minister' being one of 'priestly service'
so that the offering of the Gentiles may be acceptable, makes absolutely no sense. The only way it makes sense if his priesthood is separate and apart from their priesthood of the believers. It can only make sense in light of a true ministerial priesthood in the NT that is indeed different than the priesthood of believers. Just as is found in the OT shadows of the Levitical priesthood and the priesthood of the nation.
