I don't argue that at all.
So then the question is how did we get to the state today where many people suppose that the first century church taught Christians that they need to have Sunday services, ignore one of the Ten Commandments (exactly 1), etc.
And
no command to not take God's name in vain in the NT either.
Thankfully all major Christian denominations today ignore that kind of solution
No command of the form "Whatever is not repeated should be deleted"
No command to keep Sunday Holy
No statement saying "Sunday is the Lord's day" or "week day one is the Lord's day"
But we do have "Sabbath..the Holy Day of the Lord" Isaiah 58:13
And we have Jesus "is Lord of the Sabbath" Mark 2:28
If you ignore enough details in Acts 18 you could get to that point.
But in actual scripture it is "every Sabbath
' gospel preaching to both gentiles and Jews INSTEAD of the much imagined "Tell them on Sabbath and then start attending on Sunday for more Gospel teaching".
In fact in Acts 13 they hear the gospel on Sabbath and then ask for more gospel teaching to be scheduled for "THE NEXT Sabbath"
NT quoting from the TEN "He who breaks one , breaks them all" James 2
NT demanding that we pay attention to ALL of Gods commandments "What matters is KEEPING God's Commandments" 1 Cor 7:`9
NT stating "The saints kEEP the Commandments of GOD AND their faith in Jesus: Rev 14:12
==========================
So how is all this getting your desired answer to the OP?? Seems to be going the opposite direction
ASK AI:
Q: Who changed the Sabbath to Sunday?
A: Emperor Constantine
"The change of the Sabbath from Saturday to Sunday is primarily attributed to Emperor Constantine, who declared Sunday a day of rest in 321 CE. Additionally, the Council of Laodicea in 363 A.D. also played a role in this transition by officially deciding that the Sabbath should be observed on Sunday."
Even so
Almost every Christian denomination on Earth affirms the continued *"unit of TEN" for Christians today
