Circumcision and Sabbath practice expose inconsistency in condemning Jesus for healing on the Sabbath.

John 7:22–23

²²Moses therefore gave unto you circumcision; (not because it is of Moses, but of the fathers;) and ye on the sabbath day circumcise a man.

²³If a man on the sabbath day receive circumcision, that the law of Moses should not be broken; are ye angry at me, because I have made a man every whit whole on the sabbath day?
