Jesus Christ and his disciples observed the biblical seventh day Sabbath as commanded by God, but in the fourth century when the sun worshipper Constantine gained control and exalted Sylvester bishop of Rome over the professing Christian world.
Once Constantine had gained control he used the idea that the Sabbath and Passover were somehow Jewish because they were observed by the Jews; even there were commanded by God for all God’s people and were not established by the Jews.
Constantine was always a sun worshipper and was never a convert. He was sprinkled on his deathbed in 337 A.D. and declared “Christian.”
Changing God’s Biblical Sabbath to Sunday
Constantine forced the professing Christians to stop obeying God and abandon God’s scriptural Friday sunset to Saturday sunset Sabbath, in favor of the day of the Invincible Sun god.
Roman Emperors portrayed Sol Invictus on their official coinage, with a wide range of legends, such as SOLI INVICTO COMITI, claiming the Unconquered Sun as a companion to the Emperor.
This inscription was used with particular frequency by Constantine
Statuettes of Sol Invictus, carried by the standard-bearers, appear in three places in reliefs on the Arch of Constantine. Constantine’s official coinage continues to bear images of Sol until 325/6. A solidus of Constantine as well as a gold medallion from his reign depict the Emperor’s bust in profile twinned (jugate) with Sol Invictus, with the legend INVICTUS CONSTANTINUS
Constantine decreed (March 7, 321) dies Solis—day of the sun, “Sunday“—as the Roman day of rest (Codex Justinianus 3.12.2):
“On the venerable day of the Sun let the magistrates and people residing in cities rest, and let all workshops be closed. In the country however persons engaged in agriculture may freely and lawfully continue their pursuits because it often happens that another day is not suitable for grain-sowing or vine planting; lest by neglecting the proper moment for such operations the bounty of heaven should be lost.”
Constantine’s triumphal arch was carefully positioned to align with the colossal statue of Sol by the Colosseum, so that Sol formed the dominant backdrop when seen from the direction of the main approach towards the arch.
