Actually, the only time "grace" and "blessed" are used together in the Scriptures, is in the following verse:
Psalm 45
2 You are the most excellent of men
and your lips have been anointed with grace,
since God has blessed you forever.
Now, some instances of Grace and Blessed:
John 1:14
The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of
grace and truth.
John 1:16
From the fullness of his
grace we have all received one blessing after another.
Acts 4:33
With great power the apostles continued to testify to the resurrection of the Lord Jesus, and much
grace was upon them all.
Romans 1:5
Through him and for his name's sake, we received
grace and apostleship to call people from among all the Gentiles to the obedience that comes from faith.
John 12:13
They took palm branches and went out to meet him, shouting, "Hosanna! " "
Blessed is he who comes in the name of the Lord!" "
Blessed is the King of Israel!"
Matthew 5:11
"
Blessed are you when people insult you, persecute you and falsely say all kinds of evil against you because of me.
Matthew 25:34
"Then the King will say to those on his right, 'Come, you who are
blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world.
The common theme here seems to be that CHRIST is blessed and full of Grace, and that through Him this is passed on to us..nothing about Mary..hmm..
Now as to Mary..well, if you read her song, it says a lot about herself. The only thing that SHE says about herself is that her sould magnifies the Lord. The rest of her song glorifies God. So, rather than Catholics bowing down to Mary and asking a dead woman to pray for them, perhaps they should give their glory to the One that Mary gives glory to: The Son of Mary; God Almighty; Jesus Christ.
