I suggest reading Galatians 5:1-6.
No, I do not observe YHVH's sacrifices, for the fact that there is no sanctified Temple to do so. Until YHVH restores it, those particular laws are inapplicable.
there is nothing written in Galatians 5:1-6 about not keeping God's law .On the contrary, Paul mentions Christ
( 2 Bear ye one another's burdens, and so fulfil the law of Christ. ) who taught us to observe the law.
Matthew 5:18-20
King James Version (KJV)
18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Christ speaking :
Mark 10 :
17 And when he was gone forth into the way, there came one running, and kneeled to him, and asked him, Good Master, what shall I do that I may inherit eternal life?
18 And Jesus said unto him, Why callest thou me good? there is none good but one, that is, God.
19
Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Defraud not, Honour thy father and mother.
20 And he answered and said unto him, Master, all these have I observed from my youth.
21 Then Jesus beholding him loved him, and said unto him, One thing thou lackest: go thy way, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, take up the cross, and follow me.
Christ taught the law of God, and Paul followed Christ. So Paul also, taught the law. Christ did not say follow the old blood covenant, like circumcision of the foreskin.
The circumcision of today is a spiritual one of the heart, meaning a Christians love for God. This is written even in the old testament.
Galatians 5:1-6
King James Version (KJV)
5 Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
2 Behold, I Paul say unto you, that if ye be circumcised ( foreskin old - " covenant " ), Christ shall profit you nothing.
3 For I testify again to every man that is circumcised, that he is a debtor to do the whole law .
Paul is repeating verse two , that every person that is circumcised for a religious purpose, he is required to keep every last word of the law, and he/she will be judged by them all. When you put yourself under the law, then even the laws that are unknown to you, you will be judged on them by God.
Only Christ was perfect and able to keep it all.
"Repentance of your sins in Jesus name " gives us the credentials to go before the throne of God, and have a sin blotted out of the book of life.
You are either under the grace given under the blood of Christ, or you are under the law, and it is you that does the choosing. When you teach that there is no forgiveness, under a specific one of those laws, you have condemned your self under the whole law, for Christ's blood is sufficient to cover any sin that is repented to; the Father in Jesus name.
Galatians 5:4 "Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace."
"Grace" is unmerited favor that you can never earn. Christ paid the price for all sin on the cross at Calvary's Hill.
4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
5 For we through the Spirit wait for the hope of righteousness by faith.
6 For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
Love is the most powerful thing in the world. "Circumcision" that is done under religious beliefs, has nothing to do with salvation.
It is done to fulfill part of the law, so when it is done for religious beliefs, it takes you out of your "hope of righteousness by faith in Jesus Christ".
This is why in the time of Grace that we are now under, all circumcision is of the heart, and that is why it is for both men and women, for it becomes a spiritual matter, and not a physical act. Both male and female have an active part in serving the living God.
Paul in another place would say this :
Romans 7:7
King James Version (KJV)
7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
There is more to Paul writings, and no one can say in all honestly that Paul taught people not to observe it, he taught the law in the completeness of Christ, once you understand all of the letters.
Remember, most of the people he addresses in the scripture you quoted, where being taught by the Pharisees that they had to observe the old covenant blood letting practices. And this is against what is written.
This not not all easy to understand, and to claim without a doubt what you are, shows me a unwillingness to study before forming conclusions .
I don't understand this completely ,but I don't allow myself to jump to conclusions when I had
inadequate time, ( years ) to study everything ; that being the case with most people, who would dare call Paul, who Christ chose , false ? That would be a grave mistake. You would be ignoring a lot of scriptures.
