It amazes me that so many Catholics are probably guilty of the 'praying mindless repetitions over and over' charge that the Protestant heretics lay on the Church.
THINK about it, dear friends in Christ... you have been given, by Our Lady Herself, the PERFECT devotional prayers, especially for those times when you are not able to pray the Office (at work, at school, etc).
The recitation of the prayers of the Most Holy Rosary is an invitation to meditate upon the life and ministry and Mysteries of Our Lord Jesus Christ! We can do this DAILY, we can do it HOURLY... even praying ONE Hail Mary brings to mind:
The Immaculate Conception (she is called full of grace)
The Advent (the Fruit of Her womb is Jesus Christ Himself)
The GREAT Mystery of Mary as Mother of GOD
And the glory of Mary as Queen of Heaven and Mother of the Faithful (we ask her intercession), which is to say, we pray AS the Church that Christ established, WITH the promise that She intercedes for us and helps us on our way to the Beatific Vision that Christ promised.
How, then, can people be so indifferent about the power of the Rosary? Each and every time we recite one or more of the Decades, we are actively seizing that time and claiming it for Our Lord through Our Lady!
Sanctity, and ultimately, sainthood, is NOT gained by ONE miracle, ONE supernatural act of charity or any such thing... sanctity and sainthood are gained by the DAILY taking up of the cross which Our Lord sees fit to give us to bear. They are gained by the humble realization that, while it is still 'day', "night is coming, when no man can work", so the faithful Catholic avails himself of EVERY means of grace while they are still to be found in this life.
Our Lady of the Most Holy Rosary, pray for us.
Sacred Heart of Jesus, have mercy on us.
