Charis

When Paul (and the Holy Spirit) said “she”, the reference can only grammatically go back to a single “woman” in verses 11 & 12 since Eve is dead and gone and she cannot do things in the future.

I think “Eve” is representative, and the passage is prophetic.

Bushnell saw it that way too. This is from her book “God’s Word to Women:

827. The “childbearing” of Revelation 12 is that same “childbearing” of 1 Timothy 2:15, of which the Apostle Paul speaks prophetically, in connection with those words about the formation of woman after man, in the spiritual sense. He says of woman: “She shall be saved through the childbearing [R. V.], if they continue in charity and holiness with sobriety.”
