Excerpt from: A Letter to the Entire Order, St. Francis of Assisi 

Almighty, eternal, just and merciful God,

give us miserable ones

the grace to do for You alone

what we know you want us to do

and always to desire what pleases You.

Inwardly cleansed,

interiorly enlightened

and inflamed by the fire of the Holy Spirit,

may we be able to follow

in the footprints of Your beloved Son,

our Lord Jesus Christ,

and by Your grace alone,

may we make our way to You,

Most High,

Who live and rule

in perfect Trinity and simple Unity,

and are glorified

God Almighty,

forever and ever.

Amen.
