"Royal edicts, general councils, and church ordinances sustained by secular power were the steps by which the pagan festival attained its position of honor in the Christian world. The first public measure enforcing Sunday observance was the law enacted by Constantine. (A.D. 321; see Appendix note for page 53.) This edict required townspeople to rest on “the venerable day of the sun,” but permitted countrymen to continue their agricultural pursuits. Though virtually a heathen statute, it was enforced by the emperor after his nominal acceptance of Christianity. GC 574.1"
"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."
Both passages deal with the enforcement of worship by secular power. Revelation 13:12 speaks of the beast causing people to worship, and the EGW passage describes Constantine's law enforcing Sunday observance, which she interprets as a step toward the papacy's agenda.
"The royal mandate not proving a sufficient substitute for divine authority, Eusebius, a bishop who sought the favor of princes, and who was the special friend and flatterer of Constantine, advanced the claim that Christ had transferred the Sabbath to Sunday. Not a single testimony of the Scriptures was produced in proof of the new doctrine. Eusebius himself unwittingly acknowledges its falsity and points to the real authors of the change. “All things,” he says, “whatever that it was duty to do on the Sabbath, these we have transferred to the Lord's Day.”—Robert Cox, Sabbath Laws and Sabbath Duties, page 538. But the Sunday argument, groundless as it was, served to embolden men in trampling upon the Sabbath of the Lord. All who desired to be honored by the world accepted the popular festival. GC 574.2"
"And through covetousness shall they with feigned words make merchandise of you: whose judgment now of a long time lingereth not, and their damnation slumbereth not."
Both passages address the issue of religious leaders using deceptive means and 'feigned words' to promote doctrines not based on scripture. The EGW passage specifically mentions Eusebius and his claim about the Sabbath, while 2 Peter 2:3 warns against those who exploit others with false teachings. The connection is strong and relevant.
"be punished with the loss of half of their estates; and finally, that if still obstinate they should be made slaves. The lower classes were to suffer perpetual banishment. GC 574.3"
"Now if ye be ready that at what time ye hear the sound of the cornet, flute, harp, sackbut, psaltery, and dulcimer, and all kinds of musick, ye fall down and worship the image which I have made; well: but if ye worship not, ye shall be cast the same hour into the midst of a burning fiery furnace; and who is that God that shall deliver you out of my hands?"
Both passages describe punishments for disobeying religious decrees. In Daniel, the punishment is being thrown into a fiery furnace for not worshipping an idol. In the EGW passage, the punishments for not observing Sunday include loss of property, enslavement, and banishment. The thematic parallel of punishment for religious disobedience is clear.
