Oh, Matthew 24.
I didn’t recognize it because as I understand it, Jesus is speaking about the destruction of Jerusalem and of the temple and the killing of 1.2 million Jews by the Romans in AD 70 rather than the end of time. The apocalyptic language is typical of the prophets.
I always thought the desolating abomination (Matthew 24:15) was a Roman God which was set up in the temple. If I remember correctly, it was the image of an Eagle which the Roman soliders set up in the temple just before it was destroyed. I have also read on the Catholic Encyclopedia that some think it refers to the Roman Standards which were set up in the temple by the Roman soldiers. You can see them at

I apologize for working from memory and that I have no references.
I remember from somewhere, I think it was a Stephen Ray talk on CD, that the veil of the temple had images of the sun, moon and starts painted on it. I know that Jewis tradition held that the rock upon which the temple was built capped of a long shaft which led to Sheol or “The Pit.” The temple was through to sit half way between Heaven and Hell and was therefor the center of the universe for the Jews. The sun, moon and starts painted on the veil which blocked the Holy of Holies would have been torn down, hence Jesus’ “The stars will fall from the sky” comment and John’s “the heavens will be rolled up” reference in the Book of Revelation. The Jews at the time would have been more familiar with this than we are.
You will hear of wars and reports of wars; see that you are not alarmed, for these things must happen, but it will not yet be the end. Nation will rise against nation, and kingdom against kingdom; there will be famines and earthquakes from place to place. All these are the beginning of the labor pains. (Matthew 24:6-8)
I do note with some interest the reference to labor pains, which I take to mean the birth of the Church. That might shed some light on what honestly does seem to reference the Parousia in verse 30 and 31.
And then the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn, and they will see the Son of Man coming upon the clouds of heaven with power and great glory. And he will send out his angels with a trumpet blast, and they will gather his elect from the four winds, from one end of the heavens to the other. (Mtthew 24:30-31)
But rather than the parousia, could Jesus have been using hyperbole to mean that he will return in the form of his kingdom, the Church? (Or even the Eucharist?) The very next verse talks of the lesson of the fig tree blossoming and that “Summer is near”. Is this the blossoming of the Church? The question posed in the orginal post, namely, how can all these things happen before one generation passes, would be satisfied by this interpretation.
I’m not saying all this. I"m just sayin’.

you know, for what it’s worth.
