Reply #7: Three possible allusions.

[Igel]

It's talking of Herod's Temple, the last Jewish temple on the Temple Mount. It was the pride and joy of the Pharisees/Sadducees, the symbol of what made Israel important.

It's saying that the day would come when there would be no stone of the temple left on top of another. Literal fulfillment, if you want to call this a prophecy, was the destruction of the Temple in what was it, 70 AD (CE)?

It's widely taken to mean more: That what we consider great will be utterly destroyed, showing how impotent we are prior to something better being built in its place. This also has two references: The first is the world/civilization/age. The second is each believer, a temple of God, who needs to be reconstructed in Christ's image.

There are other interpretations possible--some relying on traditional (or not so traditional) Xian beliefs, others just taking the quote utterly out of context and placing it in some other context.

Which is intended is entirely up to the quoter.
