“Friendship is the next Pleasure we may hope for: And where we find it not at home, or have no home to find it in, we may seek it abroad. It is an Union of Spirits, a Marriage of Hearts, and the Bond thereof Vertue.”

Speech to the Army Council (1654)

1920s, Toleration and Liberalism (1925)
Context: The generally expressed desire of 'America first' can not be criticized. It is a perfectly correct aspiration for our people to cherish. But the problem which we have to solve is how to make America first. It can not be done by the cultivation of national bigotry, arrogance, or selfishness. Hatreds, jealousies, and suspicions will not be productive of any benefits in this direction. Here again we must apply the rule of toleration. Because there are other peoples whose ways are not our ways, and whose thoughts are not our thoughts, we are not warranted in drawing the conclusion that they are adding nothing to the sum of civilization. We can make little contribution to the welfare of humanity on the theory that we are a superior people and all others are an inferior people. We do not need to be too loud in the assertion of our own righteousness. It is true that we live under most favorable circumstances. But before we come to the final and irrevocable decision that we are better than everybody else we need to consider what we might do if we had their provocations and their difficulties. We are not likely to improve our own condition or help humanity very much until we come to the sympathetic understanding that human nature is about the same everywhere, that it is rather evenly distributed over the surface of the earth, and that we are all united in a common brotherhood. We can only make America first in the true sense which that means by cultivating a spirit of friendship and good will, by the exercise of the virtues of patience and forbearance, by being 'plenteous in mercy', and through progress at home and helpfulness abroad standing as an example of real service to humanity.

Although news to many, the truth about the prayer had apparently been hiding in plain sight. “No one among the Franciscans ever thought it really was by St. Francis,” said Giovanni Maria Vian, the editor of L'Osservatore Romano.]
