Christ. Have you not read that the Sabbath was a shadow of what was to come?
I have read in Colossians that there are Sabbaths which are shadows of things to come... No-one I know has ever established the weekly Sabbath as a shadow.
What Sabbaths were shadows, and why? They were the established feast days, Passover, feast of first fruits, feast of trumpets etc, which were intimately connected to the yearly round of sanctuary service, and all those feasts were annual events. Why? Because each one pointed to a coming Savior, as also did the sanctuary itself, it's furniture, the sacrifices, and the priesthood, all shadows of a coming Savior, all intimately a part of the laws of Moses established by God through Moses as a means by which to deal with the sin problem. All connections to that sanctuary service were indeed temporary because Jesus fulfilled each one, all because of sin. The forerunner of this of course being the very first sacrifice after the fall in Eden when Jesus clothed Adam and Eve with the skins from that first sacrifice, and from thence followed a pattern, a pattern of obedience and submission to the will of God, a pattern followed by Abel costing him his life, and rejected by Cain who considered his own works as worthy.
The weekly Sabbath however was not redemptive. It was not a part of the cure for the sin problem. It was not a shadow, being established by Jesus Himself
before sin everbecame an issue for man. The weekly Sabbath was an integral component of creation week, and far from a being a shadow of something to come, was a memorial and reminder of that which had been accomplished on behalf of man... Creation. "... For in six days God created..."
On who's authority has SDA changed the MOB to Sunday worship?
Changed from what? And it isn't SDAs who is establishing the MOB,
Sunday sacredness, ...
(I object to your use of the term 'Sunday worship'... There is nothing wrong with worshipping on Sundays or any day... It's about replacing the true Sabbath with a spurious counterfeit day and calling that day holy and sacred)
... as a mark of authority for the Antichrist. It is the Papacy, who established Sunday sacredness calling it a holy day, and protestantism and the vast majority of Christendom agrees with this change...a change which I will add is only in the mind of those who accept it, as no-one, not you, me, or even any of the apostles, and certainly not an apostate church system that has thought to replace not only the true 7th day Sabbath, but everything else in the plan of salvation including Jesus Himself with counterfeit mediators, prayers, even the gospel itself. That's why she is antichrist.
