Why wouldn't you read the article first. 1. It isn't long. 2. You would understand what I mean when I say the argument is weak. Again, I am not saying what they are saying is wrong, but the argument they make is weak, while the Dispensationalists have a much stronger argument. He also completely misrepresented the Olivet Discourse, further weakening the arguments.
Now, again, the rapture does NOT find its roots in the teachings of Darby. That is why I say that you should do some research. Then you would stop commenting with falsehoods. The rapture has had some for of existence within the church, whether accepted or not, for over a millennia. Much further back then preterism, which doesn't even have a historic tradition within the church. Futurism has a historic tradition in that it is premillennial. The future part is added to that, but it is premillennial which has a historic tradition going back to the 1st/2nd century, and actually back into the Old Testament. Amillennialism has a historic tradition going back to St. Augustine, who came up with it because he had a falling out with the premillennialists of the day.
One of the copies of the Pseudo Ephraim, which is dated as between the 5th and 8th centuries, speaks of the rapture, not as the rapture in using the word rapture, but as a gathering up. When reading what it says, it is speaking of a rapture. There are other versions of the pseudo Ephraim that do not have this, but the fact that there is a manuscript dating back to that time frame that has it, means that the idea existed in some form within the church. Again, I said that the rapture is one of the ways presented for God separating the church from His wrath. There were other ways that existed throughout church history as well. One of the things used by those who spoke of a rapture of sorts is the 10 plagues in Egypt, where God eventually, before His wrath was poured out on Egypt, put a separation between Egypt and Goshen. So for some (all?) church fathers, this is a cause for consideration/reflection, considering we are talking about God pouring His wrath upon the world, and they believed God would not pour out His wrath on His adopted children.
