No, the Holy Spirit focus on the beginning of the first day, and it is during that time that the preaching service takes place, and on that day the Lord also met with disciples after the resurrection. But that you do either day to honor the Lord is the main thing, unless you think those do not keep the 7th day are all lost.
The Holy Spirit had no dog in the “first day.”
The first day was significant only in numeric order; the sabbath was the worship day, which was transitioned out during the evening after the sabbath, which just happened to be the beginning of the Hebrew work week.
