By her words and her silence the Virgin Mary stands before us as a model for our pilgrim way. It is not an easy way: as a result of the fall of our first parents, humanity is marked by the wounds of sin, whose consequences continue to be felt also among the redeemed. But evil and death will not have the last word! Mary confirms this by her whole life, for she is a living witness of the victory of Christ, our Passover.
Dear friends, in this we know we can count on Mary, who, since she never yielded to sin, is the only creature who is perfectly free. I entrust you to her. Walk beside Mary as you journey towards the complete fulfilment of your humanity!
-John Paul II (Homily in Lourdes 8/15/2004)
