The word is Charitou which derives from Charis but is only found in two forms in Scripture.
Once refering to Mary in Luke and once referring to Christians in Ephesians.
The understanding of what is grace is far different between Protestants and Catholic/Orthodox. We look at grace as "God's riches at Christ's expense." "Unmerited favor". It isn't a power someone is filled with. It is a blessing which is bestowed and is far from theologically insignificant. It is the reason we are saved. Grace. God poured His grace upon us having mercy on those who did not deserve mercy and because of Christ saving those undeserving of salvation.
Don't try claiming next time that you belong to the same Church with us, then. This being said, I doubt that you know what the Catholic teaching on grace is.
