Matthew 24:2

Every man also, who, by taking into him the word of God, is become a temple, if after sinning he yet retains in part the traces of faith and religion, his temple is in part destroyed, and in part standing. But he who after sin has no regard for himself is gradually alienated, until he has altogether forsaken the living God, and so one stone is not left upon another of God's commandments, which he has not thrown down.

For inasmuch as He said, "Your house is left desolate," and had previously forewarned them of many grievous things; therefore the disciples having heard these things, as though marvelling at it, came unto Him, showing the beauty of the temple, and wondering, if so much beauty was to be destroyed, and materials so costly, and variety of workmanship past utterance; He no longer thenceforth talks to them of desolation merely, but foretells an entire destruction. "See ye not all these things," saith He, and do ye marvel, and are ye amazed? "There shall not remain one stone upon another." How then did it remain? one may say. But what is this? For neither so hath the prediction fallen to the ground. For He said these things either indicating its entire desolation, or at that spot where He was. For there are parts of it destroyed unto the foundations. And together with its we would say another thing also, that from what hath been done, even the most contentious ought to believe concerning the remains, that they are utterly to be destroyed.

Figuratively; When the Lord departed from the temple, all the buildings of the Law and the structure of the Commandments were so overthrown, that none of them could be fulfilled by the Jews, but, the Head being taken away, all the parts were at war among themselves.

So it was ordained of God, that as soon as the light of grace was revealed, the temple with its ceremonies should be taken out of the way, lest any weakling in the faith, beholding all the things instituted of the Lord and hallowed by the Prophets yet abiding, might be gradually drawn away from the purity of the faith to a carnal Judaism.

The historical sense is clear, that in the forty-second year after the Lord's passion, the city and temple were overthrown under the Roman Emperors Vespasian and Titus.
