So what was Paul referring to here? The established laws and feast days or new ones that inevitably creep into society (Like Easter and Christmas)? At this time there were new feast days and sabbaths proposed in honor of kings and celebrations which were unBiblical. Matthew 5:18For 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.. At this time heaven and earth has not passed away. Besides, Jesus is our Example and following what He did cannot be held against us.
Well, he also mentions "Sabbaths" so the answer is pretty obvious.
But fulfillment has come.
