Jesus was the new covenant. New laws suggest the idea that new rules be adopted. Or that existing laws (like the keeping of the sabbath) be kept in a different way.
They suggest it, huh? I need a little more than a suggestion to overturn when God writes something down in stone as a Commandment. So you admit Jesus kept the Sabbath and He was perfect but you don't want to do like Jesus You want to do your own thing. Jesus had a saying about that. If you love Me keep My Commandments. I think that was to establish who loved Jesus and those who loved the wide road of the world.
Yep, a viper pit. Merry Christmas. Have fun counting how many angels can dance on the head of a pin.
