Pope Pius XI saw it differently:
The creature's love should be given in return for the love of the Creator, another thing follows from this at once, namely that to the same uncreated Love, if so be it has been neglected by forgetfulness or violated by offense, some sort of compensation must be rendered for the injury, and this debt is commonly called by the name of reparation.We owe a debt. One of the ways we can repay it is by taking this pilgrimage of prayer and meditating on Jesus's suffering.
Now, I'm not sure I can buy the metaphysics that makes me responsible for something that happened 2000 years ago. However, it's a powerful thing to contemplate the path to the cross. The way of the world is self-interest. Jesus spent his life exhorting people to choose God's way, the way of compassion and justice. These two ways collide in Christ's death.
Have things really changed in the last 2000 years? There is God's way and the world's way. Most of the time, we're not even conscious of a choice between the two or the implications of that choice. Maybe our reparations are in choosing God's way. Maybe we should compensate those who are suffering now because we do not have to suffer. Maybe our meditation should be imagining a world in which compassion and justice are the rule. Maybe we should, in the words of Pope John Paul II, make the "unceasing effort to stand beside the endless crosses on which the Son of God continues to be crucified."
