Today's readings has as it's theme "forgiveness". Here's a thought from Dag Hammerskjold: "Forgiveness breaks the chain of causality because he who ‘forgives’ you—out of love—takes upon himself the consequences of what you have done. Forgiveness, therefore, always entails a sacrifice."
And here's a reflection from Fr Foley sj : "The real motivation for forgiveness is loving gratitude. If someone has had pity on me out of love, then my authentic reaction will be deep appreciation. I will want to pass the gift on. Especially if God has forgiven me, I will want to give to someone else the liberation I have received, especially if that person has hurt me."
