Which happened several decades after the Church came into being.
Um, yes, exactly as Christ predicted in Matthew 24. And again, not coincidentally, those "several decades" are exactly the time period during which the gospel was preached throughout the empire. In other words, until the message reached every locale that Jews were found, the temple was left standing for their benefit. Once the word was properly spread, the grace period ended, and the "times of the gentiles" began. They started ending in 1948, because Christ's coming is near.
