Except for Mary, whom the angel acknowledged as “full of Grace.” How could she become so prior to Christ’s sacrifice on the cross, unless, as Catholics hold, she was specially gifted through God’s will to be born without original sin?
Many saints are spoken of as experiencing God's grace.
In fact all saints are full of God's grace, having not earned salvation on their own.
Mary was NEVER described as “full of grace”. That phrase does NOT exist in the Greek except for Christ and Stephen.
OOOPS!
