"The churches of Africa held the Sabbath as it was held by the papal church before her complete apostasy. While they kept the seventh day in obedience to the commandment of God, they abstained from labor on the Sunday in conformity to the custom of the church. Upon obtaining supreme power, Rome had trampled upon the Sabbath of God to exalt her own; but the churches of Africa, hidden for nearly a thousand years, did not share in this apostasy. When brought under the sway of Rome, they were forced to set aside the true and exalt the false sabbath; but no sooner had they regained their independence than they returned to obedience to the fourth commandment. (See Appendix .) GC 578.1"
"Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it."
The EGW passage discusses the churches of Africa holding the Sabbath and returning to obedience to the fourth commandment. This is a direct reference to and application of the principle found in Exodus 20:8-11.
"But in vain they do worship me, teaching for doctrines the commandments of men."
Both passages discuss the concept of religious practices being in vain when they are based on human commandments rather than divine ones. EGW applies this to the Sabbath/Sunday issue, while Matthew 15:9 is a general statement.
"These records of the past clearly reveal the enmity of Rome toward the true Sabbath and its defenders, and the means which she employs to honor the institution of her creating. The word of God teaches that these scenes are to be repeated as Roman Catholics and Protestants shall unite for the exaltation of the Sunday. GC 578.2"
"And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed. And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name."
The EGW passage speaks of Rome's actions to enforce its institution (Sunday) and the future repetition of these scenes. Revelation 13:15-17 describes the beast's power to enforce worship and control commerce, which aligns with the theme of enforced religious observance and persecution.
The prophecy of Revelation 13 declares that the power represented by the beast with lamblike horns shall cause “the earth and them which dwell therein” to worship the papacy—there symbolized by the beast “like unto a leopard.” The beast with two horns is also to say “to them that dwell on the earth, that they should make an image to the beast;” and, furthermore, it is to command all, “both small and great, rich and poor, free and bond,” to receive the mark of the beast. Revelation 13:11-16 . It has been shown that the United States is the power represented by the beast with lamblike horns, and that this prophecy will be fulfilled when the United States shall enforce Sunday observance, which Rome claims as the special acknowledgment of her supremacy. But in this homage to the papacy the United States will not be alone. The influence of Rome in the countries that once acknowledged her dominion is still far from being destroyed. And prophecy foretells a restoration of her power. “I saw on…
"And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon. And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed. And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live. And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed. And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:"
Ellen White directly references Revelation 13:11-16 in this passage.
"Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. Remember ye not, that, when I was yet with you, I told you these things? And now ye know what withholdeth that he might be revealed in his time. For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:"
Ellen White directly references 2 Thessalonians 2:3-8 in this passage.
"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."
Ellen White directly references Revelation 13:8 in this passage.
