but does it document the Mother of God ever sinned?
Mary was a sinner, like every human born after the fall of mankind.
We are all born with a sin nature - the life of Adam.
Mary, the sinner, acknowledged her need of a Savior.
Only sinners need a Savior to pay the price for their individual sins and who they are as a sinner.
Now, if you want a discussion, do prove she was not a sinner from Gods Word.
Grace is only operative in the presence of sin. A person without sin will never know or experience the grace of God.
In order for Mary to be a recipient of God's grace, she HAD to have sinned. without sin, she could not have been *full of grace*.
