The Pope introduced the central theme of his catechesis, reciting the words of the Lord’s Prayer: “Forgive us our trespasses, as we forgive those who trespass against us”. “It is not possible to live without forgiveness, or at least you cannot live well, especially in the family. Every day we wrong each other. We must take account of these errors that we make due to our fragility and our selfishness. However, what is required of us is to heal the wounds we make straight away, to immediately weave again the threads we have broken. If we wait too long, it all becomes more difficult. And there is a simple secret for healing wounds and undoing accusations: never let the day finish without apologising. … If we learn to say we are sorry immediately and to offer mutual forgiveness, the wounds are healed, the marriage is strengthened, and the family becomes an increasingly solid home, that resists the shocks of our evils, great and small”.
