Then of course you haven’t heard of any of these guys Ireneaus, Polycarp, Justin Martyr, and Papias.
Personally I’ll stick with this
Rev 22:18
18 I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll. 19 And if anyone takes words away from this scroll of prophecy, God will take away from that person any share in the tree of life and in the Holy City, which are described in this scroll.
Revelation 22:18 refers specifically to the book of Revelation, not to the collection of books that is the Bible.
That is why 22:18 warns specifically against the additions of the pre tribulation rapture.
And Ireneaus, Polycarp, Justin Martyr, and Papias did not write about any rapture.
Ireneaus predicted that the world would end six thousand years after it had begun. He based his calculations on the Bible verse that says that a thousand years is as a day with God (2 Pet. 3:8). “For in as many days as this world was made, in so many thousand years shall it be concluded.… In six days created things were completed: it is evident, therefore, that they will come to an end at the sixth thousand year” (AH, V:28:3). This means the end of the world would have been around 1000 A.D., although some now claim he meant 2000 A.D. Either way, he was wrong.
Polycarp wrote, “Christ comes as the Judge of the living and the dead” (EPP, II). Although rapturists teach that Christians will not be judged at the Great White Throne, the Bible clearly teaches that they will. We examined this in the final vision of The Apocalypse, but first saw it in the Olivet Discourse. In Jesus’ parable, the Master rewards the works of His servants: “Well done, good and faithful servant; you have been faithful over a little, I will set you over much; enter into the joy of your master” (Matt. 25:21). These are servants of the Master, not enemies.
Justin Martyr, too, is supposed by some rapturists to have been an early example of premillennialism. But listen to his words: “The Spirit of prophecy speaks … in this way: ‘For out of Zion shall go forth the law.… And He shall judge among the nations … and they shall beat their swords into ploughshares, and their spears into pruning-hooks: nation shall not lift up sword against nation, neither shall they learn war anymore.’ And it did so come to pass, we can convince you. For out of Jerusalem there went out into the world, men, twelve in number, and these illiterate, of no ability in speaking: but by the power of God they proclaimed to every race of men that they were sent by Christ to teach to all the word of God” (ACR, XXXIX). Justin Martyr makes it clear that he believed the peace promises of the Old Testament were a present reality.
