Oliver Cowdery spent some time in his letters discussing Moroni and his mission. I’ve previously explained the reasons why I titled my book on geography Moroni’s America. Here’s another reminder of what Orson Hyde said about Moroni on July 4, 1854. This is in the Journal of Discourses, here.
After discussing the American Revolution, Elder Hyde related Moroni’s involvement with the country. Notice the part I emphasized in bold below.
In those early and perilous times, our men were few, and our resources limited. Poverty was among the most potent enemies we had to encounter; yet our arms were successful; and it may not be amiss to ask here, by whose power victory so often perched on our banner? It was by the agency of that same angel of God that appeared unto Joseph Smith, and revealed to him the history of the early inhabitants of this country, whose mounds, bones, and remains of towns, cities, and fortifications speak from the dust in the ears of the living with the voice of undeniable truth. This same angel presides over the destinies of America, and feels a lively interest in all our doings. He was in the camp of Washington; and, by an invisible hand, led on our fathers to conquest and victory; and all this to open and prepare the way for the Church and kingdom of God to be established on the western hemisphere, for the redemption of Israel and the salvation of the world.
This same angel was with Columbus, and gave him deep impressions, by dreams and by visions, respecting this New World. Trammeled by poverty and by an unpopular cause, yet his persevering and unyielding heart would not allow an obstacle in his way too great for him to overcome; and the angel of God helped him—was with him on the stormy deep, calmed the troubled elements, and guided his frail vessel to the desired haven. Under the guardianship of this same angel, or Prince of America, have the United States grown, increased, and flourished, like the sturdy oak by the rivers of water.
To what point have the American arms been directed since the Declaration of our National Independence, and proven unsuccessful? Not one!
The peculiar respect that high Heaven has for this country, on account of the promises made to the fathers, and on account of its being the land where the mustard seed of truth was planted and destined to grow in the last days, accounts for all this good fortune to our beloved America.
