Sounds like a good topic. so here is the thread I started for your post -- I have included your full post on this first page of the thread -- see next post. ==================================== 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) 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. 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. 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. 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. 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. 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. 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 Mark 7 7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men. 8 For laying aside the Commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do. 9 And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition. 10 For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death: 11 But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free. 12 And ye suffer him no more to do ought for his father or his mother; 13 Making the Word of God of none effect through your tradition, which ye have delivered: and many such like things do ye. 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.
