2 Hungary herself knows that no gift of God either to individuals or to nations is greater then to receive by His grace the Catholic faith, and having received it, to keep it with perseverance. This gift contains an abundance of other gifts by means of which individual persons receive both eternal happiness in heaven and greatness and prosperity for their state on earth. When Stephen first clearly grasped this truth, he asked God for nothing more vehemently, indeed he labored for nothing more energetically and consistently, than to obtain the Catholic faith for his whole kingdom and to establish it on a firm foundation from the very beginning. Therefore very early he began a change of studies and offices among the Roman bishops, the kings, and the people of Hungary which future ages did not abolish. Stephen founded and built a kingdom, but received his crown only from the Roman Pontiff, for he wanted to offer his kingdom to the Apostolic See. He established many Episcopal Sees, endowing munificently, and founding piously. Accompanying these many good works was the good pleasure and indulgence of the Apostolic See in many matters altogether singular. From his faith and piety, this holy king drew the light of counsel and the best norms for ruling his kingdom. He acquired his strength from diligence in prayer, by which he put down the evil plots of public enemies and returned as victor from the attacks of his foes. - Thus under the auspices of religion, your state was born. Under the same guardian and leader, you have come at quick march not only to maturity, but also to the strength of empire and the glory of your name. Hungary has kept holy and inviolate the faith received from her king and parent as an inheritance, and this despite the great difficulties of the times, when neighboring nations were drawn from the bosom of the Church by pernicious error. Faith, obedience and devotion to the Apostolic See have remained constant in kings, bishops, and all the people. In turn We see the predilection and paternal benevolence of the Roman Pontiffs for the Hungarian people confirmed by many testimonies. Today after many centuries and many events, the original intimate friendship remains, by the blessing of God. The virtues of your ancestors are by no means lacking in their descendants. There are many laudable and fruitful labors of the episcopate: relief in calamities, zealous defense of the rights of the Church, and your constant and courageous determination to preserve the Catholic faith.
