The “woman” of Revelation 12 will be the same astronomical signs and wonders that foretold of the birth of Jesus Christ, as I understand it.
It’s what prompted the Magi to go seeking the new King to pay homage. It will appear again prior to His second coming. Born of a virgin, Virgo, approximately the month of September under our calendar, moon at her feet. Jupiter and the star Regulus appear to have played a role, and if so will again.
I’ve seen plausible efforts to regress star charts in an effort to better understand this, and if accurate, Jesus Christ was actually born in September, and the traditional date of Christmas is more representative of the time the Magi or Wise Men came bearing their gifts.
There is clear reference to Mary in this astronomical sign, but there is also the season indicated by “virgin” and the entire event points to the Lion of Judah, born of a virgin, King of the Jews, and will again.
So, this is prophecy; it’s to be fulfilled for those of physical Israel who did not accept Jesus Christ as Messiah the first go around. It represents both past and future, what has been termed a “foreshadowing” which occurs many times in the Bible from Old Testament to New.
I realize this is likely at odds with what you have been taught, but there it is.
This is ONE reading of Revelation. Another is that Revelation —alternately,”The Apocalypse,” is is prophecy in the same sense that Isaiah is prophecy: an insight into the present age with only hints of future events, events that only the people of the future will recognize, will make sense only by looking backwards. Scott Hahn has even speculated that it is mainly a coded representation of the mysteries of the Church.
