God our Savior’s name/title for His saved handmaid Mary is “Kecharitomene.”
Personally, I think this shows us so much... about the Lord!
As always, when God reveals a new name or title for someone, it has a wonderful significance. Biblically, it signifies the great things God has done for that person.
This much is certain: this one exceptional woman, the inheritor of the promises of Genesis 3:15, the primordial enemy of the Serpent, is not called “full of sin,” but “full of grace.”
Of course, this is not her doing, but the favor of “God my Savior”, in view of her exceptional role as Mother of the Savior, the very Savior whom she conceived in her womb, and whom she adored. What great things He has done for her!
God says that everyone has sinned and since it is impossible for God to lie, we know for certain that Mary sinned, just as we all have.
If your church is teaching blasphemy against the Word of God himself, why would you endorse that?
