"And it came to pass that I, Nephi, beheld that they did prosper in the land; and I beheld a book, and it was carried forth among them.
And the angel said unto me: Knowest thou the meaning of the book?
And I said unto him: I know not.
And he said: Behold it proceedeth out of the mouth of a Jew. And I, Nephi, beheld it; and he said unto me: The book that thou beholdest is a record of the Jews, which contains the covenants of the Lord, which he hath made unto the house of Israel; and it also containeth many of the prophecies of the holy prophets; and it is a record like unto the engravings which are upon the plates of brass, save there are not so many; nevertheless, they contain the covenants of the Lord, which he hath made unto the house of Israel; wherefore, they are of great worth unto the Gentiles.
And the angel of the Lord said unto me: Thou hast beheld that the book proceeded forth from the mouth of a Jew; and when it proceeded forth from the mouth of a Jew it contained the fulness of the gospel of the Lord, of whom the twelve apostles bear record; and they bear record according to the truth which is in the Lamb of God.
Wherefore, these things go forth from the Jews in purity unto the Gentiles, according to the truth which is in God.
And after they go forth by the hand of the twelve apostles of the Lamb, from the Jews unto the Gentiles, thou seest the formation of that great and abominable church, which is most abominable above all other churches; for behold, they have taken away from the gospel of the Lamb many parts which are plain and most precious; and also many covenants of the Lord have they taken away.
And all this have they done that they might pervert the right ways of the Lord, that they might blind the eyes and harden the hearts of the children of men.
Wherefore, thou seest that after the book hath gone forth through the hands of the great and abominable church, that there are many plain and precious things taken away from the book, which is the book of the Lamb of God.
And after these plain and precious things were taken away it goeth forth unto all the nations of the Gentiles; and after it goeth forth unto all the nations of the Gentiles, yea, even across the many waters which thou hast seen with the Gentiles which have gone forth out of captivity, thou seest—because of the many plain and precious things which have been taken out of the book, which were plain unto the understanding of the children of men, according to the plainness which is in the Lamb of God—because of these things which are taken away out of the gospel of the Lamb, an exceedingly great many do stumble, yea, insomuch that Satan hath great power over them,” (1 Nephi 13:20-29)
"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," (1 Nephi 14:10)
"And Jesus again showed himself unto them, for they were praying unto the Father in his name; and Jesus came and stood in the midst of them, and said unto them: What will ye that I shall give unto you?
And they said unto him: Lord, we will that thou wouldst tell us the name whereby we shall call this church; for there are disputations among the people concerning this matter.
And the Lord said unto them: Verily, verily, I say unto you, why is it that the people should murmur and dispute because of this thing?
Have they not read the scriptures, which say ye must take upon you the name of Christ, which is my name? For by this name shall ye be called at the last day;
And whoso taketh upon him my name, and endureth to the end, the same shall be saved at the last day.
Therefore, whatsoever ye shall do, ye shall do it in my name; therefore ye shall call the church in my name; and ye shall call upon the Father in my name that he will bless the church for my sake.
And how be it my church save it be called in my name? For if a church be called in Moses’ name then it be Moses’ church; or if it be called in the name of a man then it be the church of a man; but if it be called in my name then it is my church, if it so be that they are built upon my gospel.
Verily I say unto you, that ye are built upon my gospel; therefore ye shall call whatsoever things ye do call, in my name; therefore if ye call upon the Father, for the church, if it be in my name the Father will hear you;
And if it so be that the church is built upon my gospel then will the Father show forth his own works in it,” (3 Nephi 27:2-10)
