Pope John Paul II Encyclical on Divine Mercy

DIVES IN MISERICORDIA

Mary is also the one who obtained mercy in a particular and exceptional way, as no other person has. At the same time, still in an exceptional way, she made possible with the sacrifice of her heart her own sharing in revealing God's mercy. This sacrifice is intimately linked with the cross of her Son, at the foot of which she was to stand on Calvary. Her sacrifice is a unique sharing in the revelation of mercy, that is, a sharing in the absolute fidelity of God to His own love, to the covenant that He willed from eternity and that He entered into in time with man, with the people, with humanity; it is a sharing in that revelation that was definitively fulfilled through the cross. No one has experienced, to the same degree as the Mother of the crucified One, the mystery of the cross, the overwhelming encounter of divine transcendent justice with love: that "kiss" given by mercy to justice. No one has received into his heart, as much as Mary did, that mystery, that truly divine dimension of the redemption effected on Calvary by means of the death of the Son, together with the sacrifice of her maternal heart, together with her definitive "fiat."

Mary, then, is the one who has the deepest knowledge of the mystery of God's mercy. She knows its price, she knows how great it is. In this sense, we call her the Mother of mercy: our Lady of mercy, or Mother of divine mercy; in each one of these titles there is a deep theological meaning, for they express the special preparation of her soul, of her whole personality, so that she was able to perceive, through the complex events, first of Israel, then of every individual and of the whole of humanity, that mercy of which "from generation to generation" people become sharers according to the eternal design of the most Holy Trinity
