This is a baseless claim.
No. Not at all.
It seems that your entire reasoning for seeing those as referring to two different raptures is because one mentions angels and one doesn't.
If you think that is my reasoning you probably have not been reading my posts.
Do you understand how ridiculous it is to make a man-made rule like that which says that two passages can't be referring to the same event unless they contain all the same details?
I didn't make any rule.
No wonder you believe in 5 raptures (I think...is that correct?). You apparently don't think any event is ever referred to more than once in scripture.
Let's see.
The Lord comes for the dead in Christ. That is the spring barley harvest.
The Lord returns for the alive that remained. That is the summer wheat harvest. These together make up the grain harvest.
After the wheat harvest, the blindness is removed from part of Israel, and they will know what happened.
Jeremiah 8
20 The harvest is past, the summer is ended, and we are not saved.
Then 144,000 from the 12 tribes are raptured as first fruits of the fall fruit harvest.
Rev 14
3 And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth.
4 These are they which were not defiled with women; for they are virgins. These are they which follow the Lamb whithersoever he goeth. These were redeemed from among men, being the firstfruits unto God and to the Lamb.
Then the harvest comes which is the gathering from heaven and earth. The seed of the woman is gathered from the earth seen here.
Rev 14
14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
16 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
They are singing the song of Moses seen here.
Revelation 15
2 And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God.
3 And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints.
Then the two witness are raptured seen here.
Revelation 11
11 And after three days and an half the spirit of life from God entered into them, and they stood upon their feet; and great fear fell upon them which saw them.
12 And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them.
So yeah. 5 more raptures. If you don't see the rapture of the 144,000, the rapture at the harvest itself and the rapture of the two witnesses something is wrong.
