One can attempt to allegorize the Temple away, except for the Eastern Gate:
Now, once one cannot allegorize this thing, the rest need not be allegorized either, as there is no purpose for the Eastern Gate EXCEPT for the Prince, and there is no reason for the Gate, without the Temple.
How does one deny the prophets, where it is said that all the world will come to Jerusalem on the three required Holy Days. or they will receive no rain? The reason for traveling to Jerusalem is simply because of the Temple - The rest of the Holy Days do not require sacrifice.
How does one deny Ezekiel's Temple, with it's sacrifices (which are different from previous Temple sacrifices, and have never been performed)? What of the exactitude of it's measurements (which are different from the previous ones)?
How does one deny the precincts around the Temple - Speaking of physical, geographical itemization, even the the bells on the horses being dedicated to YHWH, and etc?
One cannot. The Temple is going to be there... with every bit of certainty as the Hebrew people returning to the land (denied for millennia by Replacement Theology).
Very good point—my feeling also is that Zechariah 14 certainly figures in on the need for some kind of worship center. But any construct must take into account that no further sacrifice for sin other than that of the Lamb on the Cross, whose work was finalized there, never to be repeated again.
Build it - make Him come! I’m done!
