This is the little box SDA's always use to try and keep the Sabbath debate hot running, The Cross did away with Ceremonial days period, There is no Saturday is holy or Sunday is holy in the NT covenant today, There are no special holy days at all in the NT, Including thew weekly Sabbath.
Something the SDA's refuse to deal with, Because if they did then they would have no choice but to admit that they are wrong, The word Sabbath is used 60 times in the NT
Never once is it used to teach the day as a mandatory day of worship.
And once it is actually used to show that the Sabbath no longer has the authority in New Testament as it did in the Old,
Mt 12:8 For the Son of man is Lord even of the sabbath day.
I am sure you are familiar with this verse,
Col 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
The Greek word used for Sabbath in Matt 12:8 is the very same word that is used in Col2:16
savbbaton Sabbaton (sab'-bat-on);
Word Origin: Hebrew, Noun Neuter, Strong #: 4521
the seventh day of each week which was a sacred festival on which the Israelites were required to abstain from all work
the institution of the sabbath, the law for keeping holy every seventh day of the week
a single sabbath, sabbath day
seven days, a week
KJV Word Usage and Count
sabbath day 37
sabbath 22
week 9
That is why using the the period of time that the law was in effect, from Moses to when Jesus said it is finished on the cross to support the SDA Sabbth does not mean a thing, The teaching of the NT supercedes the teaching of the Old,
The Sabbath is plainly taught as a relic of the Old law that passed away at the cross, You can ignore it all you want but it it is still clear what the NT teaches concerning the Sabbath today
yours in Christ
