Quote #4
It is substantially true that virtue or morality is a necessary spring of popular government. The rule, indeed, extends with more or less force to every species of free government. (28.1-2)
Here, Washington expands on the religious idea to make a larger argument. He previously said that religion is necessary for morality, and morality is necessary for the kind of government America wants to have. The implication is that the type of republican system the United States created can't survive without people behaving in a virtuous way—and looking at U.S. political history, we're not sure how much people listened to that part of the address.
Quote #5
Observe good faith and justice towards all nations; cultivate peace and harmony with all. Religion and morality enjoin this conduct; and can it be, that good policy does not equally enjoin it? It will be worthy of a free, enlightened, and at no distant period, a great nation, to give to mankind the magnanimous and too novel example of a people always guided by an exalted justice and benevolence. (31.1-3)
Again, Washington draws a line from religion to morality to government. He wants people to embrace the moral teachings of their religion and use them to form better relationships with other countries. He wants the United States to be the shining moral example in European-American relations. (Let's be real, the "nations" he refers to are all in Europe or European colonies.)
