“Nor, perchance did the fact which We now recall take place without some design of divine Providence. Precisely at the epoch when the American colonies, having, with Catholic aid, achieved liberty and independence, coalesced into a constitutional Republic the ecclesiastical hierarchy was happily established amongst you; and at the very time when the popular suffrage placed the great Washington at the helm of the Republic, the first bishop was set by apostolic authority over the American Church. The well-known friendship and familiar intercourse which subsisted between these two men seems to be an evidence that the United States ought to be conjoined in concord and amity with the Catholic Church. And not without cause; for without morality the State cannot endure-a truth which that illustrious citizen of yours, whom We have just mentioned, with a keenness of insight worthy of his genius and statesmanship perceived and proclaimed. But the best and strongest support of morality is religion.”
13. Another consideration claims our earnest attention. All intelligent men are agreed, and We Ourselves have with pleasure intimated it above, that America seems destined for greater things. Now, it is Our wish that the Catholic Church should not only share in, but help to bring about, this prospective greatness. We deem it right and proper that she should, by availing herself of the opportunities daily presented to her, keep equal step with the Republic in the march of improvement, at the same time striving to the utmost, by her virtue and her institutions, to aid in the rapid growth of the States. Now, she will attain both these objects the more easily and abundantly, in proportion to the degree in which the future shall find her constitution perfected. But what is the meaning of the legation of which we are speaking, or what is its ultimate aim except to bring it about that the constitution of the Church shall be strengthened, her discipline better fortified? Wherefore, We ardently desire that this truth should sink day by day more deeply into the minds of Catholics-namely, that they can in no better way safeguard their own individual interests and the common good than by yielding a hearty submission and obedience to the Church. Your faithful people, however, are scarcely in need of exhortation on this point; for they are accustomed to adhere to the institutions of Catholicity with willing souls and a constancy worthy of all praise.
From the time of Our Lord to the present, no accusation has been more persistently made against Catholics than that they cannot be good Catholics and good citizens at the same time. They owe, it is said, a divided allegiance. On the one hand they are bound to obey an infallible pope, who is the sole judge of what comes within his sphere of authority, and who may be a foreigner; and on the other they must satisfy the claims of the State to the loyalty and obedience of its subjects.
(emphases mine – but there’s more good food for thought at the entry)
And here, Br Andre Marie wrote last year in his article entitled “Catholic and Patriotic“:
Patriotism is a great virtue. To be a patriot is to love one’s fatherland. This means that it is to love the land of the people that sired you. Patriotism is a natural overflow of the virtue of piety — that is, the virtue of the home. As piety would have us rendering what is due in justice to parents and other family members, patriotism would have us render the same to our nation, its government, and our fellow citizens. Both of these are a matter of justice, for the virtues of piety and patriotism are parts of that cardinal virtue.
