OK here is a basic scripture...
1 Cor 9:
19 For though I am free from all people, I have made myself a slave to all, so that I may gain more. 20 To the Jews I became as a Jew, so that I might gain Jews; to those who are under the Law, I became as one under the Law, though not being under the Law myself, so that I might gain those who are under the Law; 21 to those who are without the Law, I became as one without the Law, though not being without the law of God but under the law of Christ, so that I might gain those who are without the Law. 22 To the weak I became weak, that I might gain the weak; I have become all things to all people, so that I may by all means save some. 23 I do all things for the sake of the gospel, so that I may become a fellow partaker of it.
See how Paul clearly states he is not under the Law.
See how Paul states he is instead under the Law of Christ.
Paul said a lot of things that many misunderstand and misuse to their own destruction, even in his day.
This was what Peter wrote about Paul's writings which is still happening today
2 Peter 3: 15 and consider
that the longsuffering of our Lord
is salvation—
as also our beloved brother Paul, according to the wisdom given to him, has written to you, 16 as also in all his epistles, speaking in them of these things,
in which are some things hard to understand, which untaught and unstable people twist to their own destruction,
as they do also the rest of the Scriptures. 17 You therefore, beloved, since you know
this beforehand, beware lest you also fall from your own steadfastness,
being led away with the error of the wicked; 18 but grow in the grace and knowledge of our Lord and Savior Jesus Christ.
The wicked here means lawless. Paul did not teach lawlessness which he tells us in his own words:
What matters is keeping the commandments of God 1 Cor 7:19
Christ and God are One so there is no conflict between the law of Christ and God.
Jesus is our example who kept the Sabbath Luke 4:16, John 15:10, the apostles is our example who kept the Sabbath preaching to Jews and Gentile every Sabbath Acts 18:4. The Sabbath will continue as God's chosen day of worship for eternity just like God promised Isaiah 66:23, Exodus 31:16
We if can't get past these easy scriptures, going deeper does not make sense. We will have to agree to disagree. Take care.
