The words "it is finished" meant more than Christ giving up the spirit.
The prophesies ended. Apocalypses are visions. Not prophesies.
Then I asked him, "Lord, how shall we be able to prophesy to those who request us to prophesy to them? For there are many who ask us, and look to us to hear an oracle from us."
The Lord answered and said, "Do you not know that the head of prophecy was cut off with John?"
But I said, "Lord, can it be possible to remove the head of prophecy?"
The Lord said to me, "When you come to know what 'head' means, and that prophecy issues from the head, (then) understand the meaning of 'Its head was removed.' At first I spoke to you in parables, and you did not understand; now I speak to you openly, and you (still) do not perceive. -Secret James
Revelations has come true for many hundreds of orthodox believers throughout the last few millennia. The 1844 thing will soon be replaced with a new "deadline" or "event".
The early churches didn't include apocalyptic books ( by John, Peter, James, Paul, etc.).
The Apocalypse of Paul:
Then the Holy Spirit who was speaking with him caught him up on high to the third heaven, and he passed beyond to the fourth heaven. The Holy Spirit spoke to him, saying, "Look and see your likeness upon the earth." And he looked down and saw those who were upon the earth. He stared and saw those who were upon the [...]. Then he gazed down and saw the twelve apostles at his right and at his left in the creation; and the Spirit was going before them.
The Apocalypse of Peter:
15. And the Lord showed me a very great country outside of this world, exceeding bright with light, and the air there lighted with the rays of the sun, and the earth itself blooming with unfading flowers and full of spices and plants, fair-flowering and incorruptible and bearing blessed fruit. 16. And so great was the perfume that it was borne thence even unto us. 17. And the dwellers in that place were clad in the raiment of shining angels and their raiment was like unto their country; and angels hovered about them there. 18. And the glory of the dwellers there was equal, and with one voice they sang praises alternately to the Lord God, rejoicing in that place. 19. The Lord saith to us: This is the place of your high-priests, the righteous men.
20. And over against that place I saw another, squalid, and it was the place of punishment; and those who were punished there and the punishing angels had their raiment dark like the air of the place.
21. And there were certain there hanging by the tongue: and these were the blasphemers of the way of righteousness; and under them lay fire, burning and punishing them. 22. And there was a great lake, full of flaming mire, in which were certain men that pervert righteousness, and tormenting angels afflicted them.
23. And there were also others, women, hanged by their hair over that mire that bubbled up: and these were they who adorned themselves for adultery; and the men who mingled with them in the defilement of adultery, were hanging by the feet and their heads in that mire. And I said: I did not believe that I should come into this place.
24. And I saw the murderers and those who conspired with them, cast into a certain strait place, full of evil snakes, and smitten by those beasts, and thus turning to and fro in that punishment; and worms, as it were clouds of darkness, afflicted them. And the souls of the murdered stood and looked upon the punishment of those murderers and said: O God, thy judgment is just.
25. And near that place I saw another strait place into which the gore and the filth of those who were being punished ran down and became there as it were a lake: and there sat women having the gore up to their necks, and over against them sat many children who were born to them out of due time, crying; and there came forth from them sparks of fire and smote the women in the eyes: and these were the accursed who conceived and caused abortion.
I fail to see spiritual knowledge in any of them. They are fleshly. and a stick to the carrot of orthodoxy.
Christ said to teach the Gospel. (GOOD news). And Paul taught us how to think.
Philippians:
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
