This idea of course not being realized as above, but via one Jew who is a priest and king, by Jesus. So perhaps now Jesus is the only priest and king which might mean that the two class system is now defunct save for Jesus over all people. So now there is no priestly class at all because it was just part of a prophetic arrangement that was always going to include all nations on the earth. It was there to begin with because God had to start somewhere and in order to prepare the Jewish mind for the idea that God wanted to include all people as his one people in the future.
Amen! Absolutely. Right on. I think of what Jesus said to the Pharisees about the Old Testament Scriptures, "These are they that speak of me." Also he said, "That all the things written about me in the law, prophets, and psalms". The main theme of the Bible, especially the religious system of the Old Testament, is Jesus Christ and him crucified as a substitutionary sacrifice for sinners. That is essentially the main objection to the Catholic system. The priesthood has been fulfilled in Christ. There is now a "priesthood of all believers".
1 Peter 2:9 seems to be a key verse. "But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light." (ESV)
As Martin Luther wrote in his, "To the Christian Nobility of the German Nation" in 1520:
That the pope or bishop anoints, makes tonsures, ordains, consecrates, or dresses differently from the laity, may make a hypocrite or an idolatrous oil-painted icon, but it in no way makes a Christian or spiritual human being. In fact, we are all consecrated priests through Baptism, as St. Peter in 1 Peter 2[:9] says, "You are a royal priesthood and a priestly kingdom," and Revelation [5:10], "Through your blood you have made us into priests and kings."
Two months later Luther wrote in his "On the Babylonian Captivity of the Church":
How then if they are forced to admit that we are all equally priests, as many of us as are baptized, and by this way we truly are; while to them is committed only the Ministry and consented to by us? If they recognize this they would know that they have no right to exercise power over us (in what has not been committed to them) except insofar as we may have granted it to them, for thus it says in 1 Peter 2, "You are a chosen race, a royal priesthood, a priestly kingdom." In this way we are all priests, as many of us as are Christians. There are indeed priests whom we call ministers. They are chosen from among us, and who do everything in our name. That is a priesthood which is nothing else than the Ministry. Thus 1 Corinthians 4:1: "No one should regard us as anything else than ministers of Christ and dispensers of the mysteries of God."
