I see what you are saying about Hebrews 10, however, I can't see that this temple is only to make Israel ashamed. I see this as a literal temple in the last days, especially based on other scriptures that talks about the last days. Now the question is why would the sacrifices be brought back? Although you don't agree, I do see that them as a re-establishment of the the laws that Israel broke, and God making Israel holy before Him. So they must go through all the laws they broke. I know you don't agree!
Here's something you're probably not considering. Granted, this is my own thinking and that I might be the only person on the planet that has thought some of this through in this manner, thus, maybe no one but me has considered it. Regardless what the case may be, here's what I'm assuming you are not taking into consideration before deciding how to interpret these last 8 chapters in Ezekiel.
Ezekiel 43:7 And he said unto me, Son of man, the place of my throne, and the place of the soles of my feet, where I will dwell in the midst of the children of Israel for ever, and my holy name, shall the house of Israel no more defile, neither they, nor their kings, by their whoredom, nor by the carcases of their kings in their high places.
8 In their setting of their threshold by my thresholds, and their post by my posts, and the wall between me and them, they have even defiled my holy name by their abominations that they have committed: wherefore I have consumed them in mine anger.
9 Now let them put away their whoredom, and the carcases of their kings, far from me, and I will dwell in the midst of them for ever.
10 Thou son of man, shew the house to the house of Israel, that they may be ashamed of their iniquities: and let them measure the pattern.
11 And if they be ashamed of all that they have done, shew them the form of the house, and the fashion thereof, and the goings out thereof, and the comings in thereof, and all the forms thereof, and all the ordinances thereof, and all the forms thereof, and all the laws thereof: and write it in their sight, that they may keep the whole form thereof, and all the ordinances thereof, and do them.
12 This is the law of the house; Upon the top of the mountain the whole limit thereof round about shall be most holy. Behold, this is the law of the house.
In this passage the son of man is meaning Ezekiel, and is obviously meaning while he was still alive. What was he to do while he was still alive? He was to shew the house to the house of Israel, that they may be ashamed of their iniquities: and let them measure the pattern. That means the house of Israel meant is also alive at the time Ezekiel was. To project all of this into the future would have to mean that Ezekiel first needs to be resurrected, then the house of Israel living when he did, they also need to be resurrected, and once all of those things happen, the resurrected Ezekiel is to then shew the house to the resurrected house of Israel, that they may be ashamed of their iniquities: and let them measure the pattern.
And if they be ashamed after all of them being resurrected first, the resurrected Ezekiel is to then shew them the form of the house, and the fashion thereof, and the goings out thereof, and the comings in thereof, and all the forms thereof, and all the ordinances thereof, and all the forms thereof, and all the laws thereof: and write it in their sight, that they may keep the whole form thereof, and all the ordinances thereof, and do them.
How can any of these things not involve Ezekiel himself? And if we project this into the future, nothing recorded in the last 8 chapters involve Ezekiel during the time he was physically alive on the earth, but involve a time after everyone is resurrected first. IOW, to project these events into the future would mean Ezekiel was to never actually show the house of Israel alive in his day and age any of these things, but he was to wait until he is resurrected first, then he is to show them these things.
