Since Sabbath is on Saturday, and Sabbath was (and is) the day of rest (for both God and man), this is incorrect. Furthermore, Christians made the first day of the week -- Sunday -- the day of Christian worship and rest, because Christ rose on this day. Therefore it is also called "the Lord's Day" (Rev 1;10). Christ Himself gave this day a special significance by waiting for seven days before meeting with Thomas after His resurrection on the following Sunday. He could have appeared the very next day, but Jesus was setting a pattern for Christians. Paul also waited for seven days to meet with the disciples on "the first day of the week" in Troas.
It's not incorrect at all.
1. Dan. 9:27 says Jesus was supposed to die on a Wednesday. And since Jesus said He would be dead for 3 full days and nights, that brings His resurrection time to Saturday.
2. Jesus gave no special significance to Sunday at all, because the NT scriptures continually refer to it as "the first day of the week". The fact that the NT continues to refer to it without a name shows there is nothing special about it. On the other hand, the last day of the week is constantly referred to as "
the Sabbath". It doesn't say "the Jewish Sabbath" or "the day that was formerly known as the Sabbath".
3. Rev. 1:10 is referring to the last year of the Tribulation when God begins to collectively punish unrepentant people in this world for their sins. A true bible student can know this because plenty of OT books like Joel refers to it. "Christians" would know this if they didn't reject the authority of the OT.
Contrary to what people believe, that passage is not referring to a day of the week whatsoever. And even if it did, it still wouldn't be Sunday because Jesus Himself said He is Lord of
the Sabbath(Mar. 2:28). The Sabbath is His day, not any of the other 6 days.
4. Man does not possess the authority to make anything holy, and you won't be able to find any scripture that support this heresy, try as you might to twist Paul's words in Rom. 14. God already consecrated the last day of the week from the very beginning of creation, and He stated in the Decalogue that the
7th day is to be preserved as it was created. You will not find any scripture that says God changed His mind on that.
5. No true Christian ever sanctified Sunday as the "Christian Sabbath" because Acts shows Paul keeping the Sabbath as God commanded it in the Decalogue. It's interesting how Protestants talk so much about Catholics elevating their traditions above scripture when they do the exact same thing, even though most of their customs, doctrines, and habit of rejecting scripture came from the Catholics.
Plenty of Catholic scholars throughout the last 200-300 years alone have all admitted that there is
0 biblical evidence for a change to Sunday, and that everyone who observers Sunday does so on the Catholic church's authority.
