The Pope took the name after St Francis of Assissi, the founder of the Jesuits. St Francis's traditional prayer is maybe a good one for the world now. (I don't know how to make spoilers work in mobile, or I would spoiler the prayer, sorry!)
Lord, make me an instrument of your peace,
Where there is hatred, let me sow love;
Where there is injury, pardon;
Where there is doubt, faith;
Where there is despair, hope;
Where there is darkness, light;
Where there is sadness, joy.
O Divine Master, grant that I may not so much seek to be consoled, as to console;
to be understood, as to understand,
to be loved, as to love.
For it is in giving that we receive.
It is in pardoning that we are pardoned,and it is in dying that we are born to Eternal Life. Amen.
