Well lets look at Abraham then. he was a man righteous before God and before all the ceremonial and dietary laws were handed down These laws were for the Jewish people for a certain time in history. The ten commandments are not dietary nor ceremonial and Christ did not go against them. Ceremonial and dietary, He certainly did. His coming changed everything.

He worked on the Sabbath!  What dietary challenges did he make?  Would you say 'what have you to do with me?' is a way of honouring your mother?
