Oh, I agree! Thus how does Mary being full a grace translate to Mary being sinless? I am curious of the Biblical foundation for the equating of being grace-filled meaning sinless.
Catholics believe that Mary was sinless because she housed the God-Christ child in her womb?
My common sense tells me that God,the father, would not choose Mary unless she was deemed sinless. Remember, The Holy Spirit?
Conceived through the Holy Spirit......thus we have all three persons of the Trinity in this story. God the Father willing it so, God the Holy Spirit through which God the Son, was made human, an extreme act of humility on the part of Jesus Christ, to become Man, but acutally insignificant when we look to the extreme humility of Christ the Son of God dying on the Cross for our sins.
