20 Such brotherly affection, truly Christian and practiced as long as the Church can remember, has traditionally sought a special efficacy from the Mother of God, since she has been the foremost promoter of peace and unity. St. Germain of Constantinople addresses this prayer to her: "Be mindful of Christians who are thy servants; commend the prayers of all; help all to realize their hopes; strengthen the faith; keep the Church in unity."(14) And to this day the Greeks beseech her in this manner: "O Virgin most pure, whose privilege it is to approach thy Son without fear of rebuff! Beseech Him, O Virgin most holy, to grant peace to the world and to breathe into the churches of Christendom one mind and one heart; and we shall all magnify thee."(15)
