Did Mary Ever Did a Sin?

Did Mary ever did a sin? That's a question in the mind of the people who have weak faith in the Blessed Mother of God. Now that is a question we are going to answer. Here is a verse the Protestants use to claim that the Blessed Mother did a sin...

"all have sinned and are deprived of the glory of God" - Romans 3:23 (New American Bible)

That verse says that all have sinned and are deprived of the glory of God. That verse, as I said is the verse the Protestants & other religions (such as the Born Again Christians, the Baptists, the Jehovah's Witnesses, etch.) are using to proof that Mary did a sin. But it's not a verse to proof that Mary ever did a sin. The Bible says that Mary is a favored one...

"And coming to her, he said, "Hail, favored one! The LORD is with you" - Luke 1:28 (New American Bible)

Mary is God's favored one for the Lord Jesus Christ. God trusted Mary to become the Mother of the Lord Jesus Christ. But in the Jewish time (before the crucifixion of the Lord Jesus Christ), all are sinners and God would not trust sinners. Then, why God picked Mary to be the Mother of a man/God who doesn't do any sin? Because Mary is perfect. Mary is Conception. Before Jesus was crucified to the cross, God wouldn't trust any sinner to become the Mother of God. But Mary is picked by God to be the Mother of the Son of God. That is my answer to thew question, did Mary ever did a sin. Shalom and God bless us all.
