I bolded the unbiblical statement you made. There is zero scripture to say that Mary's mom had an immaculate conception. The logical process is that every woman in Mary's lineage going back to Eve, before the fall, would have to be sinless in order for your claim tone true.
No, God promised after the fall that he would put enmity between satan and the woman. Satan attacked through a woman, God restored through a woman.
Eve and all her progeny were under Satan’s dominion.
Mary was saved by God from sin so that her seed, conceived of her would save the world.
You are sharing a non-biblical tradition that came along after Mary's death from your church making things up.
If Mary (and all the women in her lineage before her) was sinless then she would never have died. Sin causes death. A sinless person would not die.
Mary isn’t dead, she is both Body and Soul in Heaven. If you can point to her grave, every Catholic and Orthodox Church member would like to know, believe me.
The mother in Revelation 12 is the church, not Jesus earthly mom.
Catholics see Mary as The Ark of the New Covenant.
The special purpose of The Ark of the Covenant, was to be an Immaculate and fitting Throne of God, so that God could manifest Himself and be among His people.
The Shekinah Glory “ overshadowed “ The Ark of The Covenant, The Holy Spirit “ overshadowed “ Mary at the Incarnation of Jesus in her womb.
The Ark of The Covenant contained 3 things, Manna, the Rod of Aaron ( priestly authority) and Word of God The Ten Commandments.
These were the prefiguements of Jesus, The Manna The Bread of Life, the priestly Authority of High Priest ,the rod of Aaron, Jesus The Eternal Word of God the Ten commandments.
The Ark of the Covenant had to be made to the most exacting requirements and purity instructed by God before he could reside in it.
Even the gold ( symbolising purity ) had to be paid for only in unblemished Passover lamb skins. Estimated to be nearly 200,000 skins. Even how the gold was paid for was important, that’s how pure the Ark had to be.
Pure inside and out covered in Gold inside and out.
God alone made Mary to His standards to be The Ark of The New Covenant so that Jesus had a fitting and pure Throne when He manifested Himself at The Incarnation.
God saved Mary from any impurity, so that she could conceive Jesus in purity to be the unblemished Sacrifice that redeemed the world.
John saw the Ark of the Covenant in Heaven, a woman clothed with the sun, standing on the moon, with a crown of 12 stars.
He “raises the lowly” as Mary says.
Like I echo the scriptures, the Almighty has done great things for her.
