To Zabardas, Duke of Sardinia, on Peace with the Barbaricini

Gregory to Zabardas, and so on. From the letters of my brother and fellow bishop Felix, and of the servant of God Cyriacus, we have learned of your glory’s good qualities. And we give great thanks to mighty God that Sardinia has such a duke, one who knows how to do his duty to the state in earthly matters and also how to show Almighty God dutiful regard for the heavenly homeland. For they have written to me that you are arranging terms of peace with the Barbaricini on such conditions as to bring these same Barbaricini into the service of Christ. I rejoice greatly at this, and, if it pleases Almighty God, I will soon make your good gifts known to our most serene princes. So complete what you have begun. Show the devotion of your heart to Almighty God, and help with all your power those we have sent to your region for the conversion of the Barbaricini, knowing that such works can do much to help you both before our earthly princes and in the eyes of the heavenly King.
