The thing with Paul is his extraordinary attention toward living beyond the law. Not without the law, but rather beyond it.
Perhaps the best way to explain him is in this analogy:
We are all under the law of the United States Constitution. That law is there to protect citizens, but by and large, all law is written FOR criminals - The reason we have laws against murder and rape is because there are criminals and the law provides authority to prosecute those criminals in the protection of the citizen.
Paul writes mile after mile about how a citizen is not affected by the law, because the citizen is *not* a criminal. While some of us (myself for sure) have tasted justice delivered against us by the law of the United States, for the most part, we enjoy the laws because we are good citizens - They benefit us because we live according to their standard, and we are not cursed by them because we are not criminals.
Because we have been given clemency, does that mean we are free to break the law? Of course not! But by being good citizens, given another chance, by abiding in the law, we establish the justice of it! Being found capable of flying right once granted mercy! Therein one lives 'beyond' the law.
If one sees difference in the principles laid down by Yeshua, Peter, Paul, John, etc. one must needfully be interpreting things wrongly... and it is time for another look:
The Torah is forever.
Yeshua cannot have changed (add to or taken from) the Torah.
Yeshua said to do and teach the Torah.
The disciples cannot change (add to or take from) the words of their Master.
With those principle things established, interpretation becomes very limited.
Stop trying to put people back under the law and Torah. We are in the dispensation of grace.
We can’t keep all the feast days properly because there is no more Temple at which to offer the appropriate sacrifices, nor is there a priesthood to offer them.
It is IMPOSSIBLE to correctly keep the feast days. What you are advocating isn’t even keeping the feast days properly, but just observing the shadow of the shadow.
