I agree that this is the standard Amill interpretation
Spiritual Israel, not secular Israel, and there were always two, like there is today, and not Mary,--- it is the church in the wilderness, Acts 7:38
woman, in painful labor, gave birth to a son who ascended to his throne, the remnants of her seed have the testimony of Jesus Christ.
Mary, Jesus, Body of Christ.
Since the Body of Christ is the Church, you can use typology, and Paul, to bring Israel into it, but the woman who gave birth to a Son who ascended to heaven.. is obviously Mary.
The Church did not give birth to Christ, the Church was instituted by Christ.
