Pour forth, we beseech you, O Lord, your grace into our hearts, that we, to whom the Incarnation of Christ you Son was made known by the message of an Angel, may, through the intercession of the Blessed Virgin Mary, by his Passion and Cross be brought to the glory of his Resurrection. Who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever.

Our Lady of the Rosary is a title of the Virgin Mary related to the prayer of the Rosary, whose origin has been attributed to an apparition of Our Lady to St Dominic in 1208 in the church Prouille, near Carcasonne in the south of France.
Pope Pius V instituted the feast of “Our Lady of Victory” to commemorate the naval victory of Don John of Austria over the Turkish fleet at Lepanto on the 7 October 1571, the first Sunday of the month. The victory was attributed to the help of the Mother of God, because a rosary procession had been offered on that day in St. Peter’s Square in Rome for the success of the League in preventing Muslim forces from overrunning Western Europe. Two years later, at the request of the Dominican Order, Pope Gregory XIII in 1573 allowed this feast to be kept in all churches which possessed an altar dedicated to the Holy Rosary. In 1671 the observance of the feast was extended by Pope Clement X to the whole of Spain.
Somewhat later Pope Clement XII, following the victory over the Turks gained by Prince Eugene on 6 August 1716 (the feast of our Lady of the Snows), at Peterwardein in Hungary, decreed that the Feast of the Rosary be celebrated by the whole Church on the first Sunday in October.
Pope Pius X changed the date to 7 October and in 1969, Pope Paul VI changed the name of the feast to “Our Lady of the Rosary”. Today’s celebration invites all of us to meditate often on the mysteries of Jesus’ life.
“The rosary, though clearly Marian in character, is at heart a Christ-centered prayer. It has all the depth of the gospel messge in its entirety. It is an echo of the prayer of Mary, her perennial Magnificat for the work of the redemptive Incarnation which began in her virginal womb.... It can be said that the rosary is, in some sense, a prayer-commentary on the final chapter of the Vatican II Constitution Lumen Gentium, a chapter that discusses the wondrous presence of the Mother of God in the mystery of Christ and the Church"
(Pope John Paul II, apostolic letter The Rosary of the Virgin Mary).
