Excerpts from Insights into the Mind and Personality of the Prophet Joseph Smith by Donald Q. Cannon:
... As I studied these research materials on Joseph Smith, it became evident that he was a patriot in the best sense of the word. He frequently expressed his loyalty to the United States of America and often praised the government and especially the Constitution. Once, while pointing out some problems in that time, he nevertheless concluded, “With all our evils we are better situated than any other nation.”[29] His patriotic feelings are further expressed in these examples:
The Constitution . . . is a glorious standard; it is founded in the wisdom of God. It is a heavenly banner.[30]
I am the greatest advocate of the Constitution of the United States.[31]
