Firstly - no, the pre-tribulation rapture is invalid because it is neither found in the Bible, nor in the 1800 years of Christian life and teachings
Secondly, this was "discovered" in the sense that Darby made it up, out of whole cloth
Darby gave us details of his theory in his books and we can check his reasoning using the same Bible that he used. Darby cannot validate the Bible; it is the other way around. You attack the messenger without verifying the message -- and I've read through his reasoning, as a consequence of reading through the various dispensationalist discussions -- and both dispensationalism and the pre-tribulation rapture do not stand up to what is written in the Bible nor in the 2000 years of Christian beliefs and thoughts)
Seven_0: Do you think that because something was discovered recently it is not valid?

No, Darby tweaked it. The PTR was already known as “FUTURISM”, a concept developed out of the Catholic Counter Reformation to deflect criticism that the Catholic Church was the Antichrist power (which they are). It was developed by Francisco Ribera, Cardinal Robert Bellarmine, Michael Walpole, and Manuel De Lacunza, all JESUITS. Lacunza took points from the previous three, and wrote a book called “The Coming of the Messiah in Glory and Majesty”. Edward Irving discovered this book, originally written in Spanish, and translated it into English, titled “The Coming of Messiah in Glory and Majesty with a Preliminary Discourse”. He began to preach on it. Then, Margaret Macdonald, one of his church members, had visions/utterances on the topic. Then enters John Darby:
John Nelson Darby (1800–1882), a Church of Ireland clergyman, later with the Plymouth Brethren, also promoted Futurism and a secret rapture. Darby attended the series of meetings on Bible Prophecy that began in 1830 at Powerscourt, Ireland, and at these conferences Darby apparently learned about the secret rapture as revealed by vision to Margaret McDonald, and promoted by Edward Irving, and he soon visited Margaret MacDonald at her home in Port Glasgow, Scotland. Darby later visited America several times between 1859 and 1874, where his Futurist theology was readily accepted.
The PTR theory came from nowhere else other than the Roman Catholic Church, in an attempt to hoodwink Protestants into believing that they are not the Antichrist power. It would appear to be working, as most don’t believe it.
