The law with the purification works were abolished. Jesus also changed other commands because he was fulfilling them.
Jesus came and taught a new covenant with new guidelines and rules.
The old law is no more for anyone. You can't even get your own story straight.
How is a way to purify yourself a law held against you? LOL
What was abolished was the ordinance, ordnance coming to kill you...your debt of eternal death...
That New Covenant was taught and exemplified WHILE HE WAS ALIVE...and christening it to a room full of jews not a gentile among them...His shed blood signed that New Covenant and His death as testator to it SEALED IT
His followers still hurried to prepare Him for burial get Him off the tree before morning(ALSO OT)...AND KEEP THE SABBATH as per the commandment...and also the passover...Paul demonstrated and instructed to keep Sabbaths and the feast with new unleavened bread
and Peter the dieatary law...
If the Law could be changed why not change it before He had to be sacrificed?
Not “My will” He said or your will...but HIS WILL be done...boom...HIS LAW IS ETERNAL
