Let's start with the "sola scriptura" case for Sunday vs the Bible Sabbath.
1. There is not one NT or OT text saying "week day 1 is the Holy Day of the LORD" but we DO have that for Sabbath in Is 58:13. (AND we do not have ONE text in the NT or OT that says "week day 1 is the LORD's Day)
You are not consistent in your logic.
You want to limit evidence to the NT for the first day of the week for believers to worship (our position), but at the same time, you go to the OT to say that the Sabbath is for NT worship. You are not consistent.
If it is the NT that teaches the first day of the week is for worship, then it will also be the NT that would teach the 7th day is the day we should worship. Be consistent.
This is a NT teaching for believers who are in the Church Age living under grace and not under the law.
2. There is not ONE text in the NT or OT that says that "they met EVERY week-day-1 for gospel teaching" for both Jews AND gentiles but we DO have that for Sabbath in Acts 18:4-6.
Then do as Paul did. Be a follower of Paul in all things. Be consistent. This is your problem. You are not consistent.
Paul did not worship in a NT way on the Sabbath day, according to Acts 18.
He went into the Synagogue and worshiped with the Jews. He was a Rabbi and used his status as a Rabbi to his advantage. Unless you do as Paul did, and start entering into the synagogues your argument is worthless.
Acts 18:4 And
he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.
--How many synagogues have you reasoned in?
3. There is not ONE text in the NT or OT that says "they met week-day-1 after week-day-1 " for anything - but we DO have that in Acts 13 and Acts 17 regarding Sabbath for both Jews AND Gentiles.
There are times where the expression "first day of the week" is used and is used in such a way to indicate that it was their practice.
Here is one:
1 Corinthians 16:2 Upon
the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
--Paul would come to them on the first day of the week, the day that they assembled together as a church and brought their offerings. From there he would take their offerings or collect them so that he could go back to Jerusalem and distribute them among the poor saints there. It was a regular practice to meet on the first day of the week. That is when they brought "what God had prospered them." We do the same today.
4. There is not ONE text in the NT or OT saying "from week day 1 to week day 1 shall ALL MANKIND come before Me to worship" - but we DO have that in Is 66:23 for the Sabbath.
And there isn't such a text in the NT either. You are not consistent with scripture. Verse 22 speaks of a new heaven and a new earth, therefore you are speaking out of ignorance--that which you have no knowledge of.
5. There is not ONE text in the NT or OT saying "
the Son of man is LORD of week day 1" but we DO have that in the NT for the Sabbath in
Mark 2:28.
You are absolutely wrong here!
Acts 10:36 The word which God sent unto the children of Israel, preaching peace by
Jesus Christ: (he is Lord of all).
--Christ is Lord of ALL--Sunday, Monday, Tuesday, etc. He is not just Lord of Saturday, he is Lord of everyday, and everyday is holy unto the Lord.
6. There is not ONE text in the NT saying "there REMAINS therefore a week-day 1 rest for the people of God" but we DO have that for Sabbath in Heb 4.
You are misquoting and do not understand the verse. The passage makes a contrast.
First, this chapter is more about faith and belief then it is about the Sabbath. The Sabbath cannot bring salvation. Only faith in Christ can do that.
Hebrews 4:2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.
3 For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.
--Faith in the gospel brings salvation; brings rest,
if one believes in Christ.
Hebrews 4:6 Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:
--Salvation (God's rest) is denied to those who do not have faith. Salvation is by faith and faith alone. Only in that way can one entered into God's rest, a rest which is provided without works, BTW.
Hebrews 4:9 There remaineth therefore a rest to the people of God.
10 For he that is entered into his rest, he also hath ceased from his own works, as God did from his.
--The rest is salvation by faith and not of works. There is no rest without salvation by faith.
This entire passage is about faith or belief as contrasted to those that don't believe.
7. There is not ONE text in NT or OT saying "remember week-day-1 to keep it holy" but we DO have that in Ex 20:8 for the Sabbath.
You are not quoting from the NT!! You are inconsistent.
8. There is NOT ONE text in NT or OT saying it is ok by God if we bend/edit/break/ignore one of the TEN Commandments - but we DO have condemnation for doing such a thing in the NT -- by the Words of Christ Himself!
Mark 7:6-13
No one here bends the scripture (your own unique terminology.)
NOTE: There is no command anywhere for a Gentile believer to keep the Sabbath and you in all your years here have never been able to point to one.
That is a case of Christ demonstrating the way that the magisterium is hammered "sola scriptura" in the cases where it's traditions and "doctrines of men" are at odds with scripture
It is the SDA that keeps unscriptural traditions, even hypocritical ones saying they keep the Sabbath when in truth they don't.
Is the Bible evidence really so distasteful to you - that "what does the internet say SDAs do on Sabbath" is your choice alternative?
I would have thought that "what does the Pope say" would at a "minimum" made second-place in your list of alternatives to the Bible.
It should be of great concern to you that you do not/cannot keep the Sabbath and thus play the part of a hypocrite in claiming that you do. why would you do that? Aren't you concerned?
The Sabbath was a command given to a specific people (Israel--Ex.31), living in a specific area of the world.
Perhaps you heard of the recent rescue of the two research scientists that were recently rescued from a research center in the Antarctic. They were rescued by pilots from here in Alberta who have experience flying in inclement weather or extreme temperatures. In North America this is the middle of summer. But in the Antarctic, the only light, if there be any, comes from the moon. The sun does not rise nor does it set. It is complete darkness day and night now for a number of weeks, as it will be complete daylight at Christmas time.
The nation of Israel did not live in the Antarctic nor near the Arctic. No one can keep the Sabbath in areas where the sun does not set or rise. It was a command given to the nation of Israel in a geographical area where it could be kept. You can't keep it. I have already demonstrated that; but you don't care.
