Mary was a sinner in need of a Savior just as every human being who has ever walked the face of this earth has needed a Savior, other than Jesus Christ himself.
Familiarize yourself with the Book of Genesis regarding the source of sin and why Mary, too, was a sinner because she was born in sin. She couldn’t *not* be a sinner, but she could be forgiven.
It’s a shame y’all accuse the Mother of God of being a sinner without any evidence of Her sins.
Lucifer hates Her also. Ever think of that?
