There was much that was sound in their creed, yet their system of religion was a form and nothing more. Theirs was a very lax morality (Matthew 5:20 ; 15:4,8 ; 23:3,14,23,25 ; John 8:7 ). On the first notice of them in the New Testament (Matthew 3:7 ), they are ranked by our Lord with the Sadducees as a "generation of vipers." They were noted for their self-righteousness and their pride (Matthew 9:11 ; Luke 7:39 ; 18:11,12 ). They were frequently rebuked by our Lord (Matthew 12:39 ; 16:1-4 ).
From the very beginning of his ministry the Pharisees showed themselves bitter and persistent enemies of our Lord. They could not bear his doctrines, and they sought by every means to destroy his influence among the people.
