Patriotism and loyalty in defense of the Constitution of the United States is constantly enjoined upon us. President McKay again this morning has made reference to the cause of liberty in his remarks. To be effective in such teaching, we must begin by inspiring in each heart the faith that the Constitution of the United States was written by inspired men whom God raised up for that very purpose.
It was Joseph Smith who has been quoted as having said that the time would come when then Constitution would hang as by a thread, and at that time when it was thus in jeopardy, the elders of this Church would step forth and save it from destruction.

Why the elders of this Church? Would it be sacrilegious to paraphrase the words of the Apostle Peter, and say that the Constitution of the United States could be saved by the elders of this Church because this Church and this Church alone has the words of eternal life? We alone know by revelation as to how the Constitution came into being, and we, alone, know by revelation the destiny of this nation. The preservation of “life, liberty and the pursuit of happiness” can be guaranteed upon no other basis than upon a sincere faith and testimony of the divinity of these teachings.
