The Sabbath Lord (Matthew 12:1-14)

The pharisees seem to have a legitimate accusation against Christ regarding a Sabbath violation.  Christ recalls for the Pharisees two events from the Old Testament.  One has to do with the priests working on the sabbath while the second has to do with a non Sabbath violation.  How do these two examples show that Christ is not guilty of the Pharisee’s accusation?  How is Christ showing his ultimate Lordship over all?
