You might also be interested to know that the Catechism basically parallels exactly the account of the end times that is narrated in Matthew 24.
“21 For then there will be great tribulation, such as has not been from the beginning of the world until now, no, and never will be. 22 And if those days had not been shortened, no human being would be saved; but for the sake of the elect those days will be shortened. The Church teaches that there will be a great tribulation right before the Second Coming.]
“23 Then if any one says to you,
Lo, here is the Christ!' or There he is!’ do not believe it. 24 For false Christs and false prophets will arise and show great signs and wonders, so as to lead astray, if possible, even the elect. 25 Lo, I have told you beforehand. The Church teaches that there will be a full-fledged Antichrist movement, and many believers will deny the faith in the face of it.]
“26 So, if they say to you,
Lo, he is in the wilderness,' do not go out; if they say, Lo, he is in the inner rooms,’ do not believe it. 27 For as the lightning comes from the east and shines as far as the west, so will be the coming of the Son of man. The Church teaches that the Second Coming is imminent.] 28 Wherever the body is, there the eagles will be gathered together. The Church teaches that many Christians who remain faithful will be martyred.]
“29 Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken; 30 then will appear the sign of the Son of man in heaven, and then all the tribes of the earth will mourn, and they will see the Son of man coming on the clouds of heaven with power and great glory; 31 and he will send out his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of heaven to the other. The Church teaches that the Second Coming and Judgment Day will happen at the same time, and the resurrection of the dead/the gathering of all Christians to Christ will occur at this time, and that all of this will happen “after the tribulation.”]
“32 From the fig tree learn its lesson: as soon as its branch becomes tender and puts forth its leaves, you know that summer is near. 33 So also, when you see all these things, you know that he is near, at the very gates. 34 Truly, I say to you, this generation will not pass away till all these things take place. The Church teaches that the fulfillment of each of these End-time things began in the very generation that saw Jesus die, and now we merely await their completion.] 35 Heaven and earth will pass away, but my words will not pass away. The Church teaches that, when these End-time prophecies are fulfilled, it will be the last day of this world’s current existence.]
“36 But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only. The Church doesn’t try to set a date for this event.]”
