The MISSION of the SDA Church is 

the 3 Angel's Messages:

[Last Call To The World]

1) 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,
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.

2) And there followed another angel, saying,
Babylon is fallen, is fallen,....

3) 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, 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 cried mightily with a strong voice, saying,
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.....,

Come out of her, My people,

that ye be not partakers of her sins,

and that ye receive not of her plagues.

Revelation 14:6-10/18:2,10
