The Book of Mormon, 2 Nephi 26:14,22

14 But behold, I prophesy unto you concerning the last days; concerning the days when the Lord God shall bring these things forth unto the children of men.

22 And there are also secret combinations, even as in times of old, according to the combinations of the devil, for he is the founder of all these things; yea, the founder of murder, and works of darkness; yea, and he leadeth them by the neck with a flaxen cord, until he bindeth them with his strong cords forever.

The Book of Mormon, Ether 8

There is strife and contention over the kingdom—Akish forms an oath-bound secret combination to slay the king—Secret combinations are of the devil and result in the destruction of nations—Modern Gentiles are warned against the secret combination that will seek to overthrow the freedom of all lands, nations, and countries.

The Book of Mormon, Ether 8:24-25

24 Wherefore, the Lord commandeth you, when ye shall see these things come among you that ye shall awake to a sense of your awful situation, because of this secret combination which shall be among you; or wo be unto it, because of the blood of them who have been slain; for they cry from the dust for vengeance upon it, and also upon those who built it up.

25 For it cometh to pass that whoso buildeth it up seeketh to overthrow the freedom of all lands, nations, and countries; and it bringeth to pass the destruction of all people, for it is built up by the devil, who is the father of all lies; even that same liar who beguiled our first parents, yea, even that same liar who hath caused man to commit murder from the beginning; who hath hardened the hearts of men that they have murdered the prophets, and stoned them, and cast them out from the beginning.

The Book of Mormon, Mormon 8:27

27 And it shall come in a day when the blood of saints shall cry unto the Lord, because of secret combinations and the works of darkness.

The Pearl of Great Price, Moses 5:31

31 And Cain said: Truly I am Mahan, the master of this great secret, that I may murder and get gain. Wherefore Cain was called Master Mahan, and he gloried in his wickedness.

Conference Report, Bruce R. McConkie, April 1979

Bands of Gadianton robbers will infest every nation, immorality and murder and crime will increase, and it will seem as though every man’s hand is against his brother.

Conference Report, Charles W. Nibley, October 1923

Brethren and sisters, let me say in closing that we have it of record, that the prophet Joseph Smith said the time would come when, through secret organizations taking the law into their own hands, not being governed by law or by due process of law, but becoming a law unto themselves, when, by those disintegrating activities, the Constitution of the United States would be so torn and rent asunder, and life and property and peace and security would be held of so little value, that the Constitution would, as it were, hang by a thread.

Conference Report, Ezra Taft Benson, April 1972

Now undoubtedly Moroni could have pointed out many factors that led to the destruction of the people, but notice how he singled out the secret combinations, just as the Church today could point out many threats to peace, prosperity, and the spread of God’s work, but it has singled out the greatest threat as the godless conspiracy. There is no conspiracy theory in the Book of Mormon — it is a conspiracy fact.

Conference Report, Ezra Taft Benson, April 1978

Yes, there is a conspiracy of evil. The source of it all is Satan and his hosts. He has a great power over men to “lead them captive at his will, even as many as would not hearken” to the voice of the Lord. (Moses 4:4.) His evil influence may be manifest through governments; through false educational, political, economic, religious, and social philosophies; through secret societies and organizations; and through myriads of other forms. His power and influence are so great that, if possible, he would deceive the very elect. As the second coming of the Lord approaches, Satan’s work will intensify through numerous insidious deceptions.

Conference Report, Ezra Taft Benson, April 1989

Pride results in secret combinations which are built up to get power, gain, and glory of the world (see Helaman 7:5; Ether 8:9, 16, 22-23; Moses 5:31). This fruit of the sin of pride, namely secret combinations, brought down both the Jaredite and the Nephite civilizations and has been and will yet be the cause of the fall of many nations (see Ether 8:18-25).

Conference Report, Ezra Taft Benson, October 1961

The Lord has declared that before the second coming of Christ it will be necessary to “… destroy the secret works of darkness, …” in order to preserve the land of Zion — the Americas. (2 Nephi 10:11-16.) The world-wide secret conspiracy which has risen up in our day to fulfil these prophecies is easily identified. President McKay has left no room for doubt as to what attitude Latter-day Saints should take toward the modern “secret combinations” of conspiratorial communism.

Conference Report, Ezra Taft Benson, October 1988

I testify that wickedness is rapidly expanding in every segment of our society (see D&C 1:14-16, 84:49-53). It is more highly organized, more cleverly disguised, and more powerfully promoted than ever before. Secret combinations lusting for power, gain, and glory are flourishing. A secret combination that seeks to overthrow the freedom of all lands, nations, and countries is increasing its evil influence and control over America and the entire world (see Ether 8:18-25).
