Also, as we both know, the laws concerning animal sacrifices were also given by God. But those also were made obsolete at the death of Christ.
Also the law of circumcision was given by God but was also made obsolete. The law of circumcision is very tied to the Sabbath law. There are passages that point to the fact that the law of circumcision superseded the law of the Sabbath if they came in conflict in anyway. For example if the circumcision day fell on the Sabbath, they would have to work on the sabbath then. They couldn't wait until the next day, it had to be done on the eight day.
So we see these laws that God made have changed, or have been made obsolete.
