The Blessed Mother's title of Our Lady of the Atonement, commemorated each year on July 9th, embraces two mysteries of our faith: first, the atonement itself – the complete and perfect at-one-ment which was achieved by our Lord Jesus Christ as He shed His Most Precious Blood upon the Cross at Calvary, through which came the reconciliation of man with God, and of man with man, making us "at one" in His Sacred Heart; and second, the role of the Virgin Mary in the perfect atonement given by God – her coöperation with the Divine Will at the annunciation, and her participation in her Son's sufferings and death as she stood at the foot of the Cross. The words which Simeon spoke to her came to pass: "Behold, this child is set for the fall and rising again of many in Israel; and for a sign which shall be spoken against; (Yea, a sword shall pierce through thy own soul also,) that the thoughts of many hearts may be revealed.”
The crowning act of redeeming love, Christ’s sacrifice on the Cross, is for all of us the means whereby mankind finds salvation, peace, and unity. There upon the Cross Jesus gave us the greatest gift: His precious life. There He gave us His Blessed Mother. There Mary stood, and there we stand next to her as her children, at the foot of the Cross.
O God, who dost gather together those that have been scattered, and who dost preserve those that have been gathered: we beseech thee, through the intercession of the most Blessed Virgin Mary, Our Lady of the Atonement; that thou wouldest pour out upon thy Church the grace of unity and send thy Holy Spirit upon all mankind, that they may be one; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
