If I was to be asked to summarize the 3 Angels message, I would declared thusly...
The Official Website Of The Seventh Day Remnant Movement
"Had those who claimed to believe the truth acted their part as wise virgins, the message would ere this have been given to every nation, kindred, tongue, and people. But five were foolish. The truth should have been proclaimed by the ten virgins, but only five had made the provision essential to join the company that walked in the light given to them.
The first, second, and third angels' messages are to be repeated. The call is to be given to the church: "Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird. For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth have waxed rich through the abundance of her delicacies. . . . Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues. For her sins have reached unto heaven, and God hath remembered her iniquities."
Many who went forth to meet the Bridegroom under the messages of the first and second angels, refused the third, the last testing message to be given to the world, and a similar position will be taken when the last call is made.
Every specification of this parable (10 virgins) should be carefully studied. We are represented either by the wise or by the foolish virgins. There are many who will not remain at the feet of Jesus, and learn of him. They have not a knowledge of his ways; they are not prepared for his coming. They have made a pretense of waiting for their Lord. They have not watched and prayed with that faith which works by love and purifies the soul. They have lived a life of carelessness. They have heard and assented to the truth, but they have never brought it into their practical life. The oil of grace is not feeding their lamps, and they are not prepared to enter into the marriage supper of the Lamb. The oil is the holy grace that is sent from heaven; and there must be an inward adorning with that grace, if we would stand when he appears." -Review & Herald, October 31, 1899 par. 10-13
Revelation 14:6-7 And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, (7) Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters.
Revelation 14:8 And there followed another angel, saying, Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication.
Revelation 14:9-11 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, (10) The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb: (11) And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.

If I was to be asked to summarize the 3 Angels message, I would declared thusly...
The Investigative Judgment has commenced exactly as prophesied at the end of the 2300 year prophecy, and because the judgment has already begun as promised, the Babylonian church and its many apostate daughters have already been clearly exposed regarding their graphically fallen state; and because they are so willingly under the control of the reprobate heart of Satan, which in turn makes any possibility of reform impossible due to the fact they now have no choice but to emulate their dying god who can never reform, the evil these dead churches now embrace is so deep within them that they will seek to venerate their dying god by trying to force billions to join them in blaspheming the Holy Ghost by demanding all worship the beast and its image that Satan created by receiving his unforgivable mark of damnation so as to please the dark heart of Satan in a desperate final act of his demonic long-prophesied desire of self-exaltation that boils in nothing more than abject hatred towards Christ.
So be it, for Christian prophecy is absolute! It cannot be changed!
