Revelation 13

John also records that as -

"...I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
2 And the beast which I saw was like unto a leopard, and his feet were as the feet of a bear, and his mouth as the mouth of a lion: and the dragon gave him his power, and his seat, and great authority."  (New Testament | Revelation 13:1 - 2)

In my own opinion, I see this beast as the -

"...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."  (Book of Mormon | 1 Nephi 13:5 - 9)

I also note that this beast had seven heads suggesting to me multiple counterfeits that may lead the saints of God astray.  And even as the saints did war against this great wickedness -

"...I saw one of his heads as it were wounded to death; and his deadly wound was healed: and all the world wondered after the beast."  (New Testament | Revelation 13:3)

Which suggests to me the changing of attitudes toward fairness, political correctness, and anti-discrimination even contrary to the commandments of God for the world -

"...worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
5 And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
6 And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.
7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world."  (New Testament | Revelation 13:4 - 8)

Apparently, the beast will have great influence over the work except those whose names are written in the book of life of the Lamb.
