“As noted, the Matthew 24 passages referring to Christ’s coming refer not to His future Bodily Return to Earth, but rather to His heavenly coming in judgment upon Jerusalem.”
Wowsers, that’s a leap! Don’t see any mention of a ‘heavenly’ return in Matthew 24.
Um, it's all about the "heavenly". The word "heaven" appears seven times in Matthew 24, several times in reference to Christ's location in the narrative; the word "earth" (not counting one reference to "earthquakes") only twice, and neither time in reference to Christ's location. Read it again:
Here's some Josephus again, to reinforce the point:
...for, before sun-setting, chariots and troops of soldiers in their armour were seen running about among the clouds, and surrounding of cities. Moreover, at that feast which we call Pentecost, as the priests were going by night into the inner [court of the] temple, as their custom was, to perform their sacred ministrations, they said that, in the first place, they felt a quaking, and heard a great noise, and after that they heard a sound as of a great multitude, saying, "Let us remove hence". -- Josephus
Hope that helps.
