The "three angels' messages" is an interpretation of the messages given by three angels in Revelation . The Seventh-day Adventist church teaches that these messages are given to prepare the world for the second coming of Jesus Christ, and sees them as a central part of its own mission.
Summary paraphrases of the 3 Angels' messages:
The Three Angels' messages of Revelation 14 are highly significant to the Seventh-day Adventist Church. In the SDA Church's official mission statement, the Three Angels' Messages are prominent: The mission of the Seventh-day Adventist Church is to proclaim to all peoples the everlasting gospel in the context of the Three Angels' messages of Revelation 14:6–12.
The Seventh-day Adventist Church has traditionally believed that it is the remnant church of Bible prophecy, and that its mission is to proclaim the three angels' messages which it used in its signs and logos, although they have changed it.
The Mission Statement of the church declares:
The image of three angels circling a globe is the church's former symbol. The current logo of the Seventh-day Adventist church has three flames encircling the globe, representing the Holy Spirit; the threefold flame is also a symbol of the three angels.
According to the understanding of the Adventist pioneers, the first angel's message occurred during the two decades prior to the spring of 1844. The message of the imminent second coming of Jesus preached by the Millerite movement then fulfilled the prophecy of the first angel's message.
The second angel's message was then preached during the summer of 1844, which was preceded by a significant number of Millerites leaving the movement, and resulted in large numbers of Christians leaving their churches ("Babylon") and joining the Advent movement.
The third angel's message is based on the idea that the "Seal of God" (Revelation 7:2) is the Sabbath commandment of the decalogue. Therefore, the "mark of the beast" is the opposite, or the keeping of Sunday as the Sabbath. Hence the close of the message, "here are they that keep the commandments of God." It is a point of emphasis among Adventists that the mark of the beast has not yet been given out.
