In the early part of the fourth century the emperor Constantine issued a decree making Sunday a public festival throughout the Roman Empire. (See Appendix.) The day of the sun was reverenced by his pagan subjects and was honored by Christians; it was the emperor’s policy to unite the conflicting interests of heathenism and Christianity. He was urged to do this by the bishops of the church, who, inspired by ambition and thirst for power, perceived that if the same day was observed by both Christians and heathen, it would promote the nominal acceptance of Christianity by pagans and thus advance the power and glory of the church. But while many God-fearing Christians were gradually led to regard Sunday as possessing a degree of sacredness, they still held the true Sabbath as the holy of the Lord and observed it in obedience to the fourth commandment.

The archdeceiver had not completed his work. He was resolved to gather the Christian world under his banner and to exercise his power through his vicegerent, the proud pontiff who claimed to be the representative of Christ. Through half-converted pagans, ambitious prelates, and world-loving churchmen he accomplished his purpose. Vast councils were held from time to time, in which the dignitaries of the church were convened from all the world. In nearly every council the Sabbath which God had instituted was pressed down a little lower, while the Sunday was correspondingly exalted. Thus the pagan festival came finally to be honored as a divine institution, while the Bible Sabbath was pronounced a relic of Judaism, and its observers were declared to be accursed. (GC 53.2) MC VC

The great apostate had succeeded in exalting himself “above all that is called God, or that is worshiped.” 2 Thessalonians 2:4. He had dared to change the only precept of the divine law that unmistakably points all mankind to the true and living God. In the fourth commandment, God is revealed as the Creator of the heavens and the earth, and is thereby distinguished from all false gods. It was as a memorial of the work of creation that the seventh day was sanctified as a rest day for man. It was designed to keep the living God ever before the minds of men as the source of being and the object of reverence and worship. Satan strives to turn men from their allegiance to God, and from rendering obedience to His law; therefore he directs his efforts especially against that commandment which points to God as the Creator.
