Thus Darby is often described as an (unlike the Seventh Day Adventists) because he, in some sense, does believe that the Jews are still the people of God.
Even so, this is only a kind of ornamental anti-supersessionism, as Darby still believed that Jews would have to suffer during the Tribulation (like everyone else who remained on earth) and that only true Christians would escape the sheer horror of the apocalypse.
Then, upon his return, Christ would rapture up the elect (the spiritual bride) and they would disappear from the face of the earth.
Of course the most famous idea in all of Darby’s work is this idea of the “rapture” – a theological concept which is certainly very popular today among evangelicals in the United States.Like the Mormons, Darby drew a sharp distinction between true Christians (i.e.Protestants), whom he collectively considered to be the “spiritual bride of Christ,” and Jews who comprised the “earthly bride.” Darby promoted the idea that Jews would receive an earthly inheritance (Israel) and Christians would be raptured up into heaven to be with Christ.In any event, it is important to note that the way in which William Miller differs from nearly all other Protestant religious leaders is that he was not Judeocentric at all.Instead he was a “supersessionist,” meaning he believed that the covenant which the Jews had once held with God was now held by Christians, i.e. Therefore, according to supersessionist belief, God no longer owed the Jews anything.
