When did this 'return' occur?:
40 When therefore the lord of the vineyard shall come, what will he do unto those husbandmen?
41 They say unto him, He will miserably destroy those miserable men, and will let out the vineyard unto other husbandmen, who shall render him the fruits in their seasons.
42 Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, The same was made the head of the corner; This was from the Lord, And it is marvelous in our eyes?
43 Therefore say I unto you, The kingdom of God shall be taken away from you, and shall be given to a nation bringing forth the fruits thereof.
44 And he that falleth on this stone shall be broken to pieces: but on whomsoever it shall fall, it will scatter him as dust.
45 And when the chief priests and the Pharisees heard his parables, they perceived that he spake of them. Mt 21
(notice how they were 'REPLACED'?)
If you're hanging your hat on the late date theory for the writing of Revelation it's weak and doesn't stand up to scrutiny at all. The book was written along about 68 A.D.. I suggest you do more research.
The dating of Revelation
Was the author of Revelation taught wrong with these specific instructions?:
1 The Revelation of Jesus Christ, which God gave him to show unto his servants, even the things which must shortly come to pass: and he sent and signified it by his angel unto his servant John;
3 Blessed is he that readeth, and they that hear the words of the prophecy, and keep the things that are written therein: for the time is at hand. Rev 1
7 And behold, I come quickly. Blessed is he that keepeth the words of the prophecy of this book.
10 And he saith unto me, Seal not up the words of the prophecy of this book; for the time is at hand.
12 Behold, I come quickly; and my reward is with me, to render to each man according as his work is.
20 He who testifieth these things saith, Yea: I come quickly. Amen: come, Lord Jesus. Re 22
While most would see an application of the first quote to the First Coming and the results which transpired after His Ascension, we still do not see all Prophecy fulfilled.
The Tribulation has not occurred, the Return of Christ has not occurred as described in Revelation 19, the First Resurrection has not occurred, and the Millennial Kingdom in which many prophecies are fulfilled has not occurred.
As to making "quickly" mean the events had to have been fulfilled soon after the writing with no future application, we see the same word used here:
Revelation 2
King James Version (KJV)
5 Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
Revelation 22:20
King James Version (KJV)
20 He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
Now, do we impose rapid fulfillment in the former as well? Sure. Does it mean that the time is short? Now really, it is simply stating that the Lord will come quickly in both.
Prophecy is always fulfilled as it is written, and we can say that when the events described in Revelation begin to unfold, the Lord will truly come quickly, and will not tarry, as the writer of Hebrews states:
Hebrews 10:37
King James Version (KJV)
37 For yet a little while, and he that shall come will come, and will not tarry.
The "coming quickly" refers to that time, just as we see here in Hebrews.
God bless.
