There is a misconception which is very popular to be thrown around in modern Christianity to rebuke the Eternal Law of Elohim.
Lawless men who hate the law will say;
"If you keep the law then you have to keep all of it", as if that was a bad thing.
They are twisting and corrupting the teaching from Paul at Galatians 5:2.
They make this statement as if it was a bad thing you would have to keep the law, which in itself is a wicked thought because it is the commandment of the living Elohim YHWH and the law is a blessing to every man. Don't you want people to obey the commands to not kill you and steal all of your things?
Often they also go through naming various commandments like it is funny, and then asking, have you sacrificed any animals lately? Implying you have not sacrificed so you are not keeping the law.
YHWH is the one who gave the commandments so they're laughing and ridiculing his word, so indeed we see these people lie if they say they know him, and they are also clueless that you can only sacrifice at the temple of YHWH.
If the temple was to be rebuilt today then yes we would be obligated to make sacrifices there if we are required because the Law is eternal and we were commanded to keep it, the Messiah himself said not a single dot even would perish from any of the law until the heavens and the earth perish.
Paul was talking about salvation and rebuking the people who were going around teaching the false gospel that you are saved through the law, when the true gospel is we are saved through Messiah Yahushua and if you seek salvation through the law then you must keep the entire law perfectly or else you no longer have salvation, so you better not sin a single time.
We all know we slip up at least from time to time and we have sinned at least once in our life, so we NEED pardoning.
We are still required to keep the law, if you are not keeping the law to the best of your ability then you have not repented from wickedness yet.
A final thing to point out, those who say this contradict and condemn themselves.
By what they are teaching then that means if you keep the commandment to not murder then you have to keep the entire law, or if you keep the commandment to love your neighbor as yourself then you have to keep the entire law, or if you keep the commandment to help the needy then you must keep the entire law, etc..
