Rapture Theology

William Braham's Rapture Theology required altering the words of the Old Testament and injecting words in the New Testament. According to Branham, the Bible's account of Enoch living 365 years was incorrect while the esoteric Book of Enoch's account of Noah conversing with Enoch was correct. Branham omitted the passages in the Old Testament describing Noah's righteousness.

He was Enoch, who claimed that he walked with God for five hundred years, and had a testimony he pleased God.
Branham, William. 1956, March 4. Making A Way

the church will go through the tribulation. But I'm talking about the Bride. The Bride won't, no, it hasn't got a sin against it at all. It's done been bleached out, and there's not even a--a--there's not even smell of it; there's nothing left. They're perfect before God. So what's any tribulation to purify them, but the others do. The church does go through the tribulation, but not the Bride. Now, now, we're just taking it in all kinds of symbols now like the--the church, Noah, the carried over type, went on out into sin. See? Now, they did go over, but Enoch went first. That was the type of the saints that would go in the--in--before the tribulation period.
Branham, William. 1963, March 21. The Fourth Seal

By extending Enoch's lifespan and disagreeing with the Biblical account of Noah's righteousness, Branham used the righteous Enoch and his translation to heaven to represent his cult following saved by the rapture while the "sinful" Noah (sinful in his version) represented Christians outside of his cult. Both pillars from which his rapture theology was constructed, however, were not Biblical.

So all the days of Enoch were three hundred and sixty-five years.
Genesis 5:23

These are the generations of Noah. Noah was a righteous man, blameless in his generation. Noah walked with God.
Genesis 6:9
