Brought up in a church that talked more about sin than grace, Fiorella always felt "forgive us our trespasses as we forgive others" hanging over her like a cloak of doom.
But the petition is really quite comforting if one thinks of it as a prayer that we all be forgiven our blunders and stupidities even as we forgive others theirs. It's a plea for peace.
Mother was good at that, living in peace. She grew up with her own mother's relatives not speaking to each other for various reasons, but, as an adult, refused to shun people herself, even ones she was mad at.
It's a matter of always leaving the door open. A matter of grace.
