I've not really read the post, just breezed over it. You began it with a lame unprovable statement concerning the date of writing of the book of Jude. I'm not even remotely interested in a premise built upon such a false flimsy unsubstantiated statement.
The generation thst sees the fulfillment of the following we are told is the generation that will not pass away, so tell us when did the fulfillment of these occur?
Matthew 24:33 So likewise ye, when ye shall see all these things, know that it is near, even at the doors.
34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
Notice verse 33 you have not explained it because verse 34 goes with it "when did they see ALL these things"? Because for the "this generation" to be the generation you say then ALL must have been fuflilled.
Let's look at these things and you tell us where you can tell us and show them ALL as fulfilled:
2 And Jesus said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down.
I can answer this as fufilled in 70 A.D.
5 For many shall come in my name, saying, I am Christ; and shall deceive many.
Fulfilled or continuing today?
6And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet.
Fulfilled or continuing?
7For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places.
Fufilled or continuing?
9Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake.
Fuflfilled or continuing?
10And then shall many be offended, and shall betray one another, and shall hate one another.
Fulfilled or continuing?
11And many false prophets shall rise, and shall deceive many.
Fulfilled or continuing?
12And because iniquity shall abound, the love of many shall wax cold.
Fulfilled or continuing?
14And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
Fulfilled, continuing or still to be fulfilled?
15When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand)
Fulfilled or yet to come? Notice the abomination must be standing in the Holy Place for 3 1/2 years before Christ returned, so this is either fulfilled and scripture should show it or yet to be fulfilled, it is not the destruction of the temple.
16 Then let them which be in Judaea flee into the mountains:
17 Let him which is on the housetop not come down to take any thing out of his house:
18 Neither let him which is in the field return back to take his clothes.
19 And woe unto them that are with child, and to them that give suck in those days!
20 But pray ye that your flight be not in the winter, neither on the sabbath day:
Fulfilled or yet to come?
21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.
24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Fulfilled or yet to be fulfilled?
25Behold, I have told you before.
26Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not.
Fulfilled or yet to come?
27For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be
29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Fulfilled or yet to come?
Keep in mind you have to have everything above fulfilled for this to be.
32 Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh:
33 So likewise ye, when ye shall see all these things, know that it is near, even at the doors.
34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
35 Heaven and earth shall pass away, but my words shall not pass away.
Fulfilled or yet to come?
36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
37 But as the days of Noah were, so shall also the coming of the Son of man be.
38 For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,
39 And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
40 Then shall two be in the field; the one shall be taken, and the other left.
41 Two women shall be grinding at the mill; the one shall be taken, and the other left.
Fulfilled or yet to come?
42 Watch therefore: for ye know not what hour your Lord doth come.
Does this apply for us or has it been fulfilled?
43 But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.
44 Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh.
Do we need to heed this or not worry about it?
45 Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season?
46 Blessed is that servant, whom his lord when he cometh shall find so doing.
47 Verily I say unto you, That he shall make him ruler over all his goods.
48But and if that evil servant shall say in his heart, My lord delayeth his coming;
49And shall begin to smite his fellowservants, and to eat and drink with the drunken;
50The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of,
51And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth
Fulfilled or yet to be fulfilled?
There must be something that proves ALL these things have been fulfilled either scriptural records or historically or they have not been fulfilled because God is not the author of confussion but satan is. God would have clearly given us direction for our lives after this point if all this had been fulfilled instead what we have is:
Revelation 22:1 And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb.
2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.
3 And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him:
4 And they shall see his face; and his name shall be in their foreheads.
5 And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
6 And he said unto me, These sayings are faithful and true: and the Lord God of the holy prophets sent his angel to shew unto his servants the things which must shortly be done.
7 Behold, I come quickly: blessed is he that keepeth the sayings of the prophecy of this book.
Again Fulfilled or yet to come? Notice verses 6 and 7 they fit your definition of Him having returned in 70 A.D. So are we all now living in the New Jerusalem?
And all this without a manuel.
