You cannot give an office to someone if you do not have that office to give away. Moses was an apostle and the priesthood is included in apostleship. True apostleship is to have the life of God living through you. The signs of apostleship are:
1. Apostolic doctrine
2. Miracle working power
3. An immortal body
Moses attained to the first two signs but died before attaining the third.
Jesus is an apostle and high priest:
“Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus;”
Some but not all Jews today have a higher soul, but both Moses and Aaron are dead and the primordial king in them, which is the second Adam, cannot connect them to the world of creation. They need a priest, a primordial king, and a high priest who attaches the priest to the World of Creation.
So the Jews’ thinking is wrong, they do not access God directly.
In any event, they admit they need Messiah, a temple and a high priest to bring the power of God into the world.
