The idea of an imminent disaster being unfolded, as cyprian states, can very hardly be reconciled with the idea that there is no pre trib rapture of the church. What imminent disaster could it possibly be that would kill all christians at once? Give a reference from cyprian that proves that the church would all die at once, if that is what you think cyprian is talking about when he states that the church is "snatched hence" from the great tribulation. Cyprian does write about the tribulation suffered by the roman authorities, I would think we should find what you are claiming he believes somewhere in these sections, no?
Here's a quotation that negates the belief that Cyprian thought the entire church should all die at once in order to be snatched hence from the great tribulation. "To the hearers also, if there are any overtaken by danger, and placed near to death, let your vigilance not be wanting; let not the mercy of the Lord be denied to those that are imploring the divine favour" (EpistleXII, 2). He says that, to the recipients of the letter, it is possible that some will die by martyrdom: he doesn't say that they will, and he doesn't say that all will either.
Further, doesn't your view go against the doctrine of inevitable presence of a godly seed on earth (Romans 11:5)?
Furthermore, Cyprian read the shepherd of hermas.
