The purpose of the Lord's day is to have a day that has nothing to do with the Sabbath because the Sabbath was a covenant day with Israel, whereas the day of resurrection is for all believers. They actually have nothing to do with each other. We have to be careful of those who would Judaize Christianity by trying to keep the law for a Saturday of Christ's resurrection (which was on Sunday) which is to confuse the covenant day with Israel with that for the Church.

The day of resurrection is a new day, the first day of the week, and has nothing to do with baal or constantine or mystery religions, but is independently the day of resurrection of Jesus Christ.

It is true Christians can assemble whenever, but as for sake of convenience, it is helpful to have a day that is commonly appropriate for the bulk of Christians on Sunday morning. However, anytime of the day or week is also acceptable. This allows for no legal requirement other than to acknowledge given the Scriptures that Jesus was raised on the first day of the week, not the last day of the week.

The 8th day is the day of resurrection, which is also the 1st day.

You are banned since you are just repeating yourself, and not seeing the mistake you have made overassuming different day Sabbaths. This is not a forum for arrogant people who can't repent.
