"It has been a standard feature of Christian preaching through the ages that the Roman destruction of Jerusalem in A.D. 70 was really God's decisive punishment of the Jewish people for their rejection of Jesus, who died around the year 30." (Steve Mason, Josephus and the New Testament)
Eusebius (A.D.325) "If any one compares the words of our Saviour with the other accounts of the historian (Josephus) concerning the whole war, how can one fail to wonder, and to admit that the foreknowledge and the prophecy of our Saviour were truly divine and marvelously strange." (Book III, Ch. VII)
"It is fitting to add to these accounts the true prediction of our Saviour in which he foretold these very events. His words are as follows: "Woe unto them that are with child, and to them that give suck in those days! But pray ye that your flight be not in the winter, neither on the Sabbath day; For there shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be." The historian, reckoning the whole number of the slain, says that eleven hundred thousand persons perished by famine and sword, and that the rest of the rioters and robbers, being betrayed by each other after the taking of the city, were slain. But the tallest of the youths and those that were distinguished for beauty were preserved for the triumph. Of the rest of the multitude, those that were over seventeen years of age were sent as prisoners to labor in the works of Egypt, while still more were scattered through the provinces to meet their death in the theaters by the sword and by beasts. Those under seventeen years of age were carried away to be sold as slaves, and of these alone the number reached ninety thousand. These things took place in this manner in the second year of the reign of Vespasian, in accordance with the prophecies of our Lord and Saviour Jesus Christ, who by divine power saw them beforehand as if they were already present, and wept and mourned according to the statement of the holy evangelists, who give the very words which be uttered, when, as if addressing Jerusalem herself, he said: "If thou hadst known, even thou, in this day, the things which belong unto thy peace! But now they are hid from thine eyes. For the days shall come upon thee, that thine enemies shall cast a rampart about thee, and compass thee round, and keep thee in on every side, and shall lay thee and thy children even with the ground." And then, as if speaking concerning the people, he says, "For there shall be great distress in the land, and wrath upon this people. And they shall fall by the edge of the sword, and shall be led away captive into all nations. And Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled." And again: "When ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh." (Book III, Ch. VII)
F.W. Farrar (1882) "the Fall of Jerusalem and all the events which accompanied and followed it in the Roman world and in the Christian world, had a significance which it is hardly possible to overestimate. They were the final end of the Old Dispensation. They were the full inauguration of the New Covenant. They were God's own overwhelming judgment on that form of Judaic Christianity which threatened to crush the work of St. Paul, to lay on the Gentiles the yoke of abrogated Mosaism, to establish itself by threats and anathemas as the only orthodoxy. Many of the early Christians and those especially who lived at Jerusalem were at the same time rigid Jews... No event less awful than the desolation of Judea, the destruction of Judaism, the annihilation of all possibility of observing the precepts of Moses, could have opened the eyes of the Judaisers from their dream of imagined infallibility. Nothing but God's own unmistakable interposition - nothing but the manifest coming of Christ - could have persuaded Jewish Christians that the Law of the Wilderness was annulled." (The Early Days of Christianity, p. 489, 490)
"It was to this event, the most awful in history - 'one of the most awful eras in God's economy of grace, and the most awful revolution in all God's religious dispensations' - that we must apply those prophecies of Christ's coming in which every one of the Apostles and Evangelists fixed these three most definite limitations - the one, that before that generation passed away all these things would be fulfilled; another, that some standing there should not taste death till they saw the Son of Man coming in His kingdom; and third, that the Apostles should not have gone over the cities of Israel till the Son of Man be come. It is strange that these distinct limitations should not be regarded as a decisive proof that the Fall of Jerusalem was, in the fullest sense, the Second Advent of the Son of Man which was primarily contemplated by the earliest voices of prophecy" (ibid., Vol. 2, p. 489)
