'Pray the Rosary'

“Wishing to be more and more transparent to the mystery of Christ in order to meditate on the ‘mysteries' of His Gospel, the Church learns at the school of Mary... I hope that all believers, together with the Virgin, may start out with determination on the path of holiness, keeping their gaze fixed on Jesus and meditating, with the Rosary, on the mysteries of salvation” (John Paul II, General Audience of 29 October 2003).
The Rosary is composed of twenty decades, each of which is the con- templation of a mystery of the Gospel. There are four sets of five decades: the joyful, the luminous, the sorrowful and the glorious.
