The Mark of The Beast/ PAPACY
The mark of the beast is the papal sabbath.—Evangelism, 234 (1899).
When the test comes, it will be clearly shown what the mark of the beast is. It is the keeping of Sunday.—The S.D.A. Bible Commentary 7:980 (1900).
The sign, or seal, of God is revealed in the observance of the seventh-day Sabbath, the Lord's memorial of creation.... The mark of the beast is the opposite of this—the observance of the first day of the week.—Testimonies for the Church 8:117 (1904).
"He causeth all, both small and great, ... to receive a mark in their right hand, or in their foreheads" (Revelation 13:16). Not only are men not to work with their hands on Sunday, but with their minds are they to acknowledge Sunday as the Sabbath.—Special Testimony to Battle Creek Church (Ph 86), 6, 7 (1897).
When the Mark of the Beast Is ReceivedLDE 224No one has yet received the mark of the beast.—Evangelism, 234 (1899).
Sundaykeeping is not yet the mark of the beast, and will not be until the decree goes forth causing men to worship this idol sabbath. The time will come when this day will be the test, but that time has not come yet. The S.D.A. Bible Commentary 7:977 (1899).
God has given men the Sabbath as a sign between Him and them as a test of their loyalty. Those who, after the light regarding God's law comes to them, continue to disobey and exalt human laws above the law of God in the great crisis before us, will receive the mark of the beast.—Evangelism, 235 (1900).
The Sabbath will be the great test of loyalty, for it is the point of truth especially controverted. When the final test shall be brought to bear upon men, then the line of distinction will be drawn between those who serve God and those who serve Him not.
While the observance of the false sabbath in compliance with the law of the state, contrary to the fourth commandment, will be an avowal of allegiance to a power that is in opposition to God, the keeping of the true Sabbath, in obedience to God's law, is an evidence of loyalty to the Creator. While one class, by accepting the sign of submission to earthly powers, receive the mark of the beast, the other, choosing the token of allegiance to divine authority, receive the seal of God.—The Great Controversy, 605 (1911).
