To the Primate, Archbishops and Bishops, of the Kingdom of Poland.
Venerable Brothers, We give you Greeting and Our Apostolic Blessing.
God in his goodness allowed Catholicism to take root in Poland at the end of the tenth century during the reign of Our predecessor Leo VIII. At the time, the efforts of King Mieszko and his Christian consort Dobrava (Dlugosz, Annalium vestrorum Scriptorum, 2, 94) encouraged the spread of Christianity. Since then pious and devout Poles have continued the faithful practice of their new religion. During this time various sects have attempted to establish themselves in Poland and to spread the seeds of their errors, heresies, and evil opinions. But the faithful Polish people have strongly withstood their efforts.
