This is a good thread with lots of good thoughts. I wanted to share what I have come to see regarding Ezekiel 44.
Ezekiel 44:15-23
But the priests the Levites, the sons of Zadok, that kept the charge of my sanctuary when the children of Israel went astray from me, they shall come near to me to minister unto me, and they shall stand before me to offer unto me the fat and the blood, saith the Lord GOD: They shall enter into my sanctuary, and they shall come near to my table, to minister unto me, and they shall keep my charge. And it shall come to pass, that when they enter in at the gates of the inner court, they shall be clothed with linen garments; and no wool shall come upon them, whiles they minister in the gates of the inner court, and within. They shall have linen bonnets upon their heads, and shall have linen breeches upon their loins; they shall not gird themselves with any thing that causeth sweat. And when they go forth into the utter court, even into the utter court to the people, they shall put off their garments wherein they ministered, and lay them in the holy chambers, and they shall put on other garments; and they shall not sanctify the people with their garments. Neither shall they shave their heads, nor suffer their locks to grow long; they shall only poll their heads. Neither shall any priest drink wine, when they enter into the inner court. Neither shall they take for their wives a widow, nor her that is put away: but they shall take maidens of the seed of the house of Israel, or a widow that had a priest before. And they shall teach my people the difference between the holy and profane, and cause them to discern between the unclean and the clean.
I believe the exchanging linen for wool means bodies. I believe it is this linen garment that Jesus Christ resurrected in and the woolen body that Jesus Christ appeared before the disciples in. I believe those who attain to the first resurrection are these Zadok that are capable are doing exactly what Jesus did. They are resurrected into a "linen" (spiritual) body and dwell in it when in the spiritual realm ministering to Christ and it is exchanged for their "wool" (flesh and bones) body when they are in the physical realm ministering to those who did not attain to the first resurrection.
