EVEN IN THE NEW TESTAMENT :
The Sabbath is still for every one. Both the seeds of Abraham and the Strangers.
(That is...) Jews and None Jews: who are called Greeks/Gentiles.

Acts 13:14-15, 42-44
''...they came to Antioch in Pisidia, and went into the synagoge on the sabbath day sat down. And after the reading of the law and the prophets... and when the Jews were gone out of the synagoge, the Gentiles begged that these words might be preached to them THE NEXT SABBATH... And THE NEXT SABBATH day almost the whole city came together to hear the word of God.''
King James Version

Both in the Old Testament
and New Testament.
We see that the Sabbath is Both for Jews and Gentiles...

Argument 3: (Clarified)

THERE ARE EVEN THOSE WHO TRY TO JUSTIFY SUNDAY OBSERVANCE FROM THE BIBLE..

Here are The Bible Texts used:
Math 12:1 ; Math 28:1 ; John 20:19 ; John 5:18 ; 1 Cor 16:1-2 ; Acts 20:7 ; Rom 14:5-6,13''

How about we discuss the half truths of your claims. That the bible is sole rule of faith what a load of bull dust. Did not the apostle say the statement standfast and hold to the traditions, which we have taught by word of mouth or by our epistles. You jehovos are nutters from the bowels of hell.

Or the fact that Lot was willing to let his daughters get r*ped by an alleged all male population of s*x starved homos*xuals. Who did not want these two angels to get r*ped. He knew they were angels etc. Why else did he lay prostrate before them? And angels could easily have defended themselves could they not? Or lets discuss the fact that ''God's'' so called holy Noah got drunk intoxicated and was allowed to be seen naked by family members. How stupid do you think we are? Or lets go with the crime of Cain. Who just finished killing his brother then the lord set a seal upon him lest these other ''people'' mean to do him harm. Which other people? Adam and eve had only Cain and Abel at that time. Yet that passage alludes to a whole civilization or populace as he went abroad. More lies.
