12 With a loving mind We also turn Our prayer to you who inhabit the province of Gniezno and Poznan. Indeed, We are pleased to recall, among other things, that We have raised to the See of Adalbert, with the consent of all of you, one of your countrymen, a man of extraordinary piety, prudence and love. We are even more pleased to see with what obedience and love you strive to be subject to his gentle rule. For this reason We are able to hope that the Catholic religion will continue to grow among you. We urge you to trust the generous equity of the Emperor. We personally experienced, on more than one occasion, what a benevolent mind he has for you. He will certainly help you if you continue in respect for law and in the praise of things well done.
