Our Lady reportedly appeared and spoke by inner locution over several decades under the title of 'The Lady of All Nations' to a woman in Amsterdam name Ida Peerdeman. She had many messages of great importance for the future of the Church. (http://www.marypages.com/AmsterdamEng...)
Lord Jesus Christ, Son of the Father, send now your Spirit over the earth.
Let the Holy Spirit live in the hearts of all nations.
That they may be preserved from degeneration, disaster and war.
May the Lady of All Nations, who once was Mary*, be our Advocate.
*The Blessed Virgin Mary
Another christian prayer ( Salve Regina) also stated Mary as our Advocate.
Hail, holy Queen, Mother of mercy,
our life, our sweetness, and our hope.
To you we cry, the children of Eve;
to you we send up our sighs,
mourning and weeping in this land of exile.
Turn, then, most gracious advocate,
your eyes of mercy toward us;
lead us home at last
and show us the blessed fruit of your womb, Jesus:
O clement, O loving, O sweet Virgin Mary. Amen.
The Virgin Mary is our Advocate and our Mother, protecting s us from threats and evil, such as a lamp that shines on the candlestick shows us the way to Jesus
Sirach 26:17 As the clear light is upon the holy candlestick; so is the beauty of the face in ripe age.
At the time when the soul leaves the body and is presented to the Lord, Our Lady will be close to us (to all of us, Catholic, Orthodox and Protestant.. ), that is why from now She want to be "our advocate," since She intercedes to the Son as being constantly in His presence.
