"The special characteristic of the beast, and therefore of his image, is the breaking of God's commandments. Says Daniel, of the little horn, the papacy: “He shall think to change times and the law.” Daniel 7:25 , R.V. And Paul styled the same power the “man of sin,” who was to exalt himself above God. One prophecy is a complement of the other. Only by changing God's law could the papacy exalt itself above God; whoever should understandingly keep the law as thus changed would be giving supreme honor to that power by which the change was made. Such an act of obedience to papal laws would be a mark of allegiance to the pope in the place of God. GC 446.1"
"And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time."
Ellen White directly references Daniel 7:25 in this passage.
"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."
The EGW passage directly echoes the core idea of 2 Thessalonians 2:4, which describes a power that exalts itself above God. While not a direct quote, the thematic similarity is strong and intentional.
"While the worshipers of God will be especially distinguished by their regard for the fourth commandment, —since this is the sign of His creative power and the witness to His claim upon man's reverence and homage,— the worshipers of the beast will be distinguished by their efforts to tear down the Creator's memorial, to exalt the institution of Rome. It was in behalf of the Sunday that popery first asserted its arrogant claims (see Appendix ); and its first resort to the power of the state was to compel the observance of Sunday as “the Lord's day.” But the Bible points to the seventh day, and not to the first, as the Lord's day. Said Christ: “The Son of man is Lord also of the Sabbath.” The fourth commandment declares: “The seventh day is the Sabbath of the Lord.” And by the prophet Isaiah the Lord designates it: “My holy day.” Mark 2:28 ; Isaiah 58:13 . GC 446.3"
"Therefore the Son of man is Lord also of the sabbath."
Ellen White directly references Mark 2:28 in this passage.
"If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the Lord, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:"
Ellen White directly references Isaiah 58:13 in this passage.
