The's the greatest saint, conceived without the stain of original sin. She's the "Queen of Heaven" and "Mother of God."
Revelation 12:1A great and wondrous sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head.
The Blessed Virgin Mary - Catholic Encyclopedia
The bride of Christ. Not Mary.
Problematic interpretation.
Catholic teaching is that Mary had no pain in childbirth (Rev 12:2)
"Then being with child, she cried out in labor and in pain to give birth."
and that she only had one child (Rev 12:17)
"And the dragon was enraged with the woman, and he went to make war with the rest of her offspring, who keep the commandments of God and have the testimony of Jesus Christ."
More than likely, the woman symbolizes the messianic community - the OT "church" if you will.
