Observance of the Sabbath was never enjoined until the Law, and as shown, under which the Spirit treats the Sabbath as part of the ceremonial law, despite assertions to the contrary made in the light of and the utter absence of the 4th commandment being repeated/reiterated while doing so for the rest, nor providing and one example of any NT church doing so.
Where is the LAW stating the first day of the week must be kept holy?
There is none, only a precedent of meeting on the first day under the New Covenant, the only specific day they are shown meeting on, which you lack, while the principle of one day of rest based on God's rest (from His atoning mission) supports this practice.
I myself after becoming a Christian (former RC) have never worked for money on the first day (Sat, even to Sun, eve) even when I used to work 6 long days a week, and refrain from personal recreation on that day, as sanctified, nor do i condemn those who hold that 7th day is the correct day, as long as the motive is to honor the Lord.
But mandating observance of the 7th day even relegating those who do not to being demonically deceived damned souls as you have done, is what i contend against. Thus it is your cultic spirit that makes your salvation suspect.
Do what you will then and bother me no more. If the fact God instituted the Sabbath at Creation means nothing to you I don’t know what will. If the fact that Jesus kept the Sabbath means nothing to you then my words will not either. The Mosaic law was abolished on the cross so that has nothing to do with the Ten Commandments that was wrote in stone by the finger of God of which a copy is in heaven this very minute in the Sanctuary ark. You will not change my mind and vice versa so there is nothing more to converse about.
The only thing damnable on this thread is your LIE about me. Show me where I have relegated any demonic deceived damned souls. Post it word for word.
