The next age is after the consummation, which is after the 1000 years of Revelation 20, and after the defeat of Satan, death and hades. With that comes the second resurrection, the final judgement and the destruction of the heavens and the Earth, with the New heavens and earth, and New Jerusalem being presented from the first verse of Revelation 21. [quotes shortened for length of comment.]
I don't have time to go over this line by line. But the disciples asked three questions, and one has to recognize by context what He says is in response to what question.
"3 As He was sitting on the Mount of Olives, the disciples came to Him privately, saying, “Tell us, when will these things happen, and what
will be the sign of Your coming, and of the [
b]end of the age?”"
"4 And Jesus answered and said to them, “See to it that no one misleads you. 5 For many will come in My name, saying, ‘I am the [
c]Christ,’ and will mislead many. 6 You will be hearing of wars and rumors of wars.
See that you are not frightened, for those things must take place, but that is not yet the end. 7 For nation will rise against nation, and kingdom against kingdom, and in various places there will be famines and earthquakes. 8
But all these things are merely the beginning of birth pangs.
9 “Then they will deliver you to tribulation, and will kill you,
and you will be hated by all nations because of My name. 10
At that time many will [d]fall away and will [e]betray one another and hate one another. 11
Many false prophets will arise and will mislead many. 12 Because lawlessness is increased, [
f]
most people’s love will grow cold. 13 But the one who endures to the end, he will be saved. 14 This gospel of the kingdom shall be preached in the
whole [g]world as a testimony to
all the nations, and
then the end will come."
"15 “
Therefore when you see the abomination of desolation which was spoken of through Daniel the prophet, standing in the holy place (let the reader understand), 16 then those who are in Judea must flee to the mountains. 17 [
h]Whoever is on the housetop must not go down to get the things out that are in his house. 18 [
i]Whoever is in the field must not turn back to get his cloak. 19 But woe to those who are pregnant and to those who are nursing babies in those days! 20 But pray that your flight will not be in the winter, or on a Sabbath. 21 For
then there will be a great tribulation,
such as has not occurred since the beginning of the world until now, nor ever will. 22 Unless those days had been cut short,
no [j]life would have been saved; but for the sake of the [
k]
elect those days will be cut short."

"29 “But
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 [
r]the sky, and the powers of [
s]the heavens will be shaken. 30 And then the sign of the Son of Man will appear in the sky, and
then all the tribes of the earth will mourn, and
they will see the Son of Man coming on the clouds of the sky with power and great glory. 31 And He will send forth His angels with a great trumpet and they will gather together His [
t]elect from the four winds, from one end of the sky to the other.

3952 (
parousía) is "used in the east as a technical expression for the
royal visit of a king, or emperor. The word means literally 'the being beside,' thus, 'the personal presence'."
The
personal presence. When Jesus is present as the unveiled King, visiting His Kingdom.

Cognate: 4930 syntéleia (from
4862 /sýn, "close together
with" and
5055 /teléō, "complete, consummate") –
culmination (completion), i.e.
when the parts come together into a whole ("
consummation") – "
an end involving many parts" (B. F. Westcott).
See 4931 (
synteléō)."
The answer Christ gives immediately doesn't answer when Jerusalem will be destroyed. But is a long answer, with quite a few "but the end is not here yet". He is speaking to the end prior to His second coming. When does Jesus say
the end comes? After this gospel of the kingdom is preached in the
whole world as a testimony in
all of the nations. He isn't speaking locally.
This is followed immediately by THEREFORE. What is that therefore there for? Knowing that the end is coming after the gospel is preached as a testimony in all of the nations (such as ours), here is what you are to know is coming. The Great Tribulation. You will recognize the final approach of the end with the abomination of desolation. Immediately after the Great Tribulation, Jesus will return physically to Earth, visible to all humanity.
"29 “But
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 [
r]the sky, and the powers of [
s]the heavens will be shaken. 30 And then the sign of the Son of Man will appear in the sky, and
then all the tribes of the earth will mourn, and
they will see the Son of Man coming on the clouds of the sky with power and great glory.
Where do we read about people mourning? Zechariah 12, right? When they see and recognize Him whom they have pierced, right? It is during this time that Zechariah 12 is fulfilled.
To meet length restrictions, the third question speaks to what comes after the millennial kingdom. That is the defeat of Satan, death and hades, the second resurrection, and the final judgement before we enter the eternal age of the new heavens and new earth. The culmination of God's purpose for the creation. All the parts coming together at the end for culmination, ending with the destruction of this creation (heavens and earth) and the introduction of the new at the beginning of Revelation 21.
The ECF did not all see everything the same, so that is a loopy way in which to decide what you believe. The Bible itself if much more reliable because it is consistent with itself. Saying the 1000 years may be signifying something is not spiritualizing and it is not turning it into a methphor. It is actually attempting to find the literal meaning---that meaning that the passage is actually saying, given it is within apocalyptic prophecy that declares at the very outset that what was in it was signifying. It does so by comparing other uses of 1000 multiples of 10, 100 or a thousand, in other apocalyptic prophecy and literature within the Bible. And even after that is done, it checks the conclusion with the whole counsel of the Bible on the Covenant of Redemption (which is the subject of the Bible). And what is found within the NT Scriptures is Jesus and the Apostles only ever speaking of two ages. This age and the age to come. And Scripture tells us what this age to come is like in the Epistles and in the OT prophecy, and most vividly int Rev 21.
Revelation is chronological though. Just understand that the millennial kingdom is not another age, but in dispensationalism (not to be confused with dispensational premillennialism), the millennial kingdom is the seventh and final dispensation. This is before one even gets to putting it into an eschatological framework. This was mentioned a couple of centuries before Darby, perhaps even earlier. Darby did NOT come up with dispensationalism, just dispensational premillennialism, with rapture and all. And even then, the idea of the rapture had been floating around in the church for centuries. (Read about brother dolcino, 13th century.) And even that rapture belief was highly developed, and well thought out. It was a false teaching, but false teachers twist things that already exist to gather followers.
