“The fight for ideals can no longer take the form of fight between nations, because the lines of division on moral questions are within the nations themselves and intersect the political frontiers.”

1930s, Speech to the Democratic National Convention (1936)
Context: We do not see faith, hope, and charity as unattainable ideals, but we use them as stout supports of a nation fighting the fight for freedom in a modern civilization.
Faith — in the soundness of democracy in the midst of dictatorships.
Hope — renewed because we know so well the progress we have made.
Charity — in the true spirit of that grand old word. For charity literally translated from the original means love, the love that understands, that does not merely share the wealth of the giver, but in true sympathy and wisdom helps men to help themselves.

1930s, Quarantine Speech (1937)
Context: There is a solidarity and interdependence about the modern world, both technically and morally, which makes it impossible for any nation completely to isolate itself from economic and political upheavals in the rest of the world, especially when such upheavals appear to be spreading and not declining. There can be no stability or peace either within nations or between nations except under laws and moral standards adhered to by all. International anarchy destroys every foundation for peace. It jeopardizes either the immediate or the future security of every nation, large or small. It is, therefore, a matter of vital interest and concern to the people of the United States that the sanctity of international treaties and the maintenance of international morality be restored.

We live in a world in which the common denominator that binds the human family together has been reduced to its simplest fundamental term—human survival.
