The destruction of the Temple foretold
When some were talking about the Temple, remarking how it was adorned with fine stonework and votive offerings, Jesus said, ‘All these things you are staring at now – the time will come when not a single stone will be left on another: everything will be destroyed.’ And they put to him this question: ‘Master,’ they said ‘when will this happen, then, and what sign will there be that this is about to take place?’
‘Take care not to be deceived,’ he said ‘because many will come using my name and saying, “I am he” and, “The time is near at hand.” Refuse to join them. And when you hear of wars and revolutions, do not be frightened, for this is something that must happen but the end is not so soon.’ Then he said to them, ‘Nation will fight against nation, and kingdom against kingdom. There will be great earthquakes and plagues and famines here and there; there will be fearful sights and great signs from heaven.’
The harvest and the vintage of the earth are ripe
In my vision I, John, saw a white cloud and, sitting on it, one like a son of man with a gold crown on his head and a sharp sickle in his hand. Then another angel came out of the sanctuary, and shouted aloud to the one sitting on the cloud, ‘Put your sickle in and reap: harvest time has come and the harvest of the earth is ripe.’ Then the one sitting on the cloud set his sickle to work on the earth, and the earth’s harvest was reaped.
Another angel, who also carried a sharp sickle, came out of the temple in heaven, and the angel in charge of the fire left the altar and shouted aloud to the one with the sharp sickle, ‘Put your sickle in and cut all the bunches off the vine of the earth; all its grapes are ripe.’ So the angel set his sickle to work on the earth and harvested the whole vintage of the earth and put it into a huge winepress, the winepress of God’s anger.

The glorious advent of Christ, the hope of Israel
673 Since the Ascension Christ’s coming in glory has been imminent, even though “it is not for you to know times or seasons which the Father has fixed by his own authority.” This eschatological coming could be accomplished at any moment, even if both it and the final trial that will precede it are “delayed”.
674 The glorious Messiah’s coming is suspended at every moment of history until his recognition by “all Israel”, for “a hardening has come upon part of Israel” in their “unbelief” toward Jesus. St. Peter says to the Jews of Jerusalem after Pentecost: “Repent therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for establishing all that God spoke by the mouth of his holy prophets from of old.” St. Paul echoes him: “For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead?” The “full inclusion” of the Jews in the Messiah’s salvation, in the wake of “the full number of the Gentiles”, will enable the People of God to achieve “the measure of the stature of the fullness of Christ”, in which “God may be all in all”.
Come, let us sing joyfully to the LORD; cry out to the rock of our salvation.
Let us greet him with a song of praise, joyfully sing out our psalms.
For the LORD is the great God, the great king over all gods,
Whose hand holds the depths of the earth; who owns the tops of the mountains.
The sea and dry land belong to God, who made them, formed them by hand.
Enter, let us bow down in worship; let us kneel before the LORD who made us.
For this is our God, whose people we are, God’s well-tended flock. Oh, that today you would hear his voice:
Do not harden your hearts as at Meribah, as on the day of Massah in the desert.
There your ancestors tested me; they tried me though they had seen my works.
Forty years I loathed that generation; I said: “This people’s heart goes astray; they do not know my ways.”
Therefore I swore in my anger: “They shall never enter my rest.”
