The observation of the sabbath, for the nation of Israel, was a very serious matter:
Exo 31:14 Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people.
How long was the obervance of this day to last?
Exo 31:16-17 Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. (17) It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
I see no indication that the sabbath would ever pass away.... As far as the nation of Israel is concerned. But what does Paul say about it?
Col 2:16-17 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: (17) Which are a shadow of things to come; but the body is of Christ.
Here we see that the Body of Christ has no restrictions in regards to meat, drink, the observance of holy days, and yes, even the sabbath. In fact, Paul even reprimanded the Galatians for their observance of such things:
Gal 4:9-11 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage? (10) Ye observe days, and months, and times, and years. (11) I am afraid of you, lest I have bestowed upon you labour in vain.
I realize that the sabbath is not expressly referred to here, but the context is dealing with the Galatians' observance of the Mosaic law. I would not at all be surprised if the sabbath was one of many things that Paul had in mind.
So where does that leave us? Either Paul or Moses was wrong, or the Body of Christ is in fact a seperate entity from that of the nation of Israel according to prophecy. In Matthew 24, (according to dispensational thought, of course) the Body of Christ is gone, and God is once again dealing specifically with his chosen nation, and they pick up right where they left off; under the law.
