What are you talking about?
What do you wish to be obfuscated?
The first five seals are opened, how difficult can that be?
Since you wish to add to Scripture, back up your assertion and give us dates and events when they were opened.
I’d like to know also. You say you are not a historicist, if you say the first seal (first horseman of the apocalypse) is the end time antichrist going forth with war, famine, pestilence in his wake (the other horsemen), then, indeed you are not a historicist. However, if you interpret the first horseman as some figure of history, Nero, one of the emperors of imperial Rome, or Papal Rome, Mussolini, etc., then you are historicist plain and simple.
If you would just tell us who you interpret the first horseman to be, it would settle the issue.
