Today is George Washington’s Birthday (Observed), popularly known as President’s Day. Washington has a rare distinction among American Presidents in that he makes a cameo appearance in a Papal encyclical (a fact which, no doubt, will be of deep significance to those who claim Washington died a Catholic) The encyclical in question is Longinqua, by Leo XIII. Here is the passage in question:
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. She, by her very nature, guards and defends all the principles on which duties are founded, and setting before us the motives most powerful to influence us, commands us to live virtuously and forbids us to transgress.
Washington’s statement on religion and morality referenced by Leo is from his farewell address:
Where is the security for property, for reputation, for life, if the sense of religious obligation desert the oaths, which are the instruments of investigation in Courts of Justice? And let us with caution indulge the supposition, that morality can be maintained without religion. Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect, that national morality can prevail in exclusion of religious principle.
