It is different from other days in character also, for He blessed it and made it holy. To deny the difference between common days and the holy day is to say that when the great Creator blesses and makes holy, it is a vain performance. That cannot be. It would take away all hope of holiness or salvation for men. The blessing is upon the day, as every soul finds who keeps it by faith.
When men choose to set apart another day than that blessed and sanctified of God, it is plainly a setting up of the humanly appointed time against the divinely appointed time. It is exalting man's sabbath against God's Sabbath. It is man exalting himself "above all that is called God." 2 Thess. 2:4.
This was what made the Roman Papacy. The apostle Paul wrote that in his day the spirit of lawlessness was already working. He said it would lead to a "falling away" from the truth of God, and the full exaltation of the man of sin. 2 Thessalonians 2. The falling away came.

In his "Essay on the Development of Christian Doctrine," Cardinal Newman (Roman Catholic) tells how rites and ceremonies were borrowed from paganism:
"Confiding then in the power of Christianity to resist the infection of evil, and to transmute the very instruments and appendages of demon worship to an evangelical use,... the rulers of the church from early times were prepared, should the occasion arise, to adopt, or imitate, or sanction the existing rites and customs of the populace, as well as the philosophy of the educated class."—Pages 371, 372.
Thus along with other adaptations came "the venerable day of the sun" (Sunday). It was by gradual process that it supplanted the Sabbath. Sir William Domville wrote:
