Exodus 20:4 Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth. 5 Thou shalt not bow down thyself to them, nor serve them.
[The Great Controversy pp 52] The decree of a general council [Second Council of Nice, A.D. 787.] finally established this system of idolatry. To complete the sacrilegious work, Rome presumed to expunge from the law of God the second commandment, forbidding image worship, and to divide the tenth commandment, in order to preserve the number. The spirit of concession to paganism opened the way for a still further disregard of Heaven's authority.
Satan tampered with the fourth commandment also, and essayed to set aside the ancient Sabbath, the day which God had blessed and sanctified, [Genesis 2:2, 3.] and in its stead to exalt the festival observed by the heathen as “the venerable day of the sun.” This change was not at first attempted openly. In the first centuries the true Sabbath had been kept by all Christians. They were jealous for the honor of God, and, believing that his law is immutable, they zealously guarded the sacredness of its precepts.
But with great subtlety, Satan worked through his agents to bring about his object. That the attention of the people might be called to the Sunday, it was made a festival in honor of the resurrection of Christ. Religious services were held upon it; yet it was regarded as a day of recreation, the Sabbath being still sacredly observed.
Exodus 20:8 Remember the sabbath day, to keep it holy. 9 Six days shalt thou labor, and do all thy work: 10 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.
May God add His blessing to the study of His word. “Good night” and God bless!
