I know that you’re sincere, Chris.
Now please understand. The sanctification of Sunday was done before the New Testament was written. It simply wasn’t included in what was chosen to be Scripture because the writings stopped the time period of coverage before the decision was made.
Maybe we should have included a final chapter in the Bible after Revelation entitled something like: Things that the Church has put into effect after the Epistles were written and are as important as the Epistles are, are documented here so that in 2000 years debates over what is right don’t occur.
You have a very bizarre perspective on what happened with the early church. I just read a book called Early Christian Heresies that I think was written by a Catholic because The Church was always capitalized. The reality of how doctrines came about is very different from what you describe here on FR.
