"When being just and honest comes at a price, pay it. When forgiving seems like a defeat, forgive. When everyone tells you to think of yourselves first, do not be afraid to put yourselves last. Be willing to give up time, money, comfort and plans to serve others. May those who see you find themselves asking: 'Why do they live in this way? Where do they get this freedom? Why do they love one another so much?'”
Pope Leo XIV
