The Book of Mormon, 1 Nephi 13:4-9
4 And it came to pass that I saw among the nations of the Gentiles the formation of a great church.
5 And the angel said unto me: Behold the formation of a church which is most abominable above all other churches, which slayeth the saints of God, yea, and tortureth them and bindeth them down, and yoketh them with a yoke of iron, and bringeth them down into captivity.
6 And it came to pass that I beheld this great and abominable church; and I saw the devil that he was the founder of it.
7 And I also saw gold, and silver, and silks, and scarlets, and fine-twined linen, and all manner of precious clothing; and I saw many harlots.
8 And the angel spake unto me, saying: Behold the gold, and the silver, and the silks, and the scarlets, and the fine-twined linen, and the precious clothing, and the harlots, are the desires of this great and abominable church.
9 And also for the praise of the world do they destroy the saints of God, and bring them down into captivity.
The Book of Mormon, 1 Nephi 14:9-17
9 And it came to pass that he said unto me: Look, and behold that great and abominable church, which is the mother of abominations, whose founder is the devil.
10 And he said unto me: Behold there are save two churches only; the one is the church of the Lamb of God, and the other is the church of the devil; wherefore, whoso belongeth not to the church of the Lamb of God belongeth to that great church, which is the mother of abominations; and she is the whore of all the earth.
11 And it came to pass that I looked and beheld the whore of all the earth, and she sat upon many waters; and she had dominion over all the earth, among all nations, kindreds, tongues, and people.
12 And it came to pass that I beheld the church of the Lamb of God, and its numbers were few, because of the wickedness and abominations of the whore who sat upon many waters; nevertheless, I beheld that the church of the Lamb, who were the saints of God, were also upon all the face of the earth; and their dominions upon the face of the earth were small, because of the wickedness of the great whore whom I saw.
13 And it came to pass that I beheld that the great mother of abominations did gather together multitudes upon the face of all the earth, among all the nations of the Gentiles, to fight against the Lamb of God.
14 And it came to pass that I, Nephi, beheld the power of the Lamb of God, that it descended upon the saints of the church of the Lamb, and upon the covenant people of the Lord, who were scattered upon all the face of the earth; and they were armed with righteousness and with the power of God in great glory.
15 And it came to pass that I beheld that the wrath of God was poured out upon that great and abominable church, insomuch that there were wars and rumors of wars among all the nations and kindreds of the earth.
16 And as there began to be wars and rumors of wars among all the nations which belonged to the mother of abominations, the angel spake unto me, saying: Behold, the wrath of God is upon the mother of harlots; and behold, thou seest all these things—
17 And when the day cometh that the wrath of God is poured out upon the mother of harlots, which is the great and abominable church of all the earth, whose founder is the devil, then, at that day, the work of the Father shall commence, in preparing the way for the fulfilling of his covenants, which he hath made to his people who are of the house of Israel.
