Though having the war of 1812 (to 1815), between the United States and Britain, in view, the author notes that "the principles which I have laid down, and enforced in these sermons, are not, however, of mere temporary interest. Whether in peace, or at war, they are of importance to a Christian community. There are the permanent principles of social order and public equity."

Chapter headings include: "The Right Discussing of Public Affairs," dealing with why "Ministers have the right of discussing from the pulpit those political question which affect Christian morals" and "The Moral Character of the US Federal Constitution;" The Moral Character of the Two Belligerents" (i.e. the national character, as moral persons, of both the United States and Britain); "The Lawfulness of Defensive War;" "The Present War," dealing with how "War in Defence of Property, Liberty, and National Independence and Honour is Lawful: and (How) Defensive War May Be for Precaution, Resistance, or Redress;" and "The Ends for Which God in His Providence Permits the Existence of this War."
