Secret Combinations Are of the Devil and Result in the Destruction of Nations
Ether 8:18–22
18 And it came to pass that they formed a secret combination, even as they of old; which combination is most abominable and wicked above all, in the sight of God;
19 For the Lord worketh not in secret combinations, neither doth he will that man should shed blood, but in all things hath forbidden it, from the beginning of man.
20 And now I, Moroni, do not write the manner of their oaths and combinations, for it hath been made known unto me that they are had among all people, and they are had among the Lamanites.
21 And they have caused the destruction of this people of whom I am now speaking, and also the destruction of the people of Nephi.
22 And whatsoever nation shall uphold such secret combinations, to get power and gain, until they shall spread over the nation, behold, they shall be destroyed; for the Lord will not suffer that the blood of his saints, which shall be shed by them, shall always cry unto him from the ground for vengeance upon them and yet he avenge them not.
President Ezra Taft Benson said:
“Our nation will continue to degenerate unless we read and heed the words of the God of this land, Jesus Christ, and quit building up and upholding the secret combinations which the Book of Mormon tells us proved the downfall of both previous American civilizations.”
