In contrast to the two commands of Christ, the Pharisees had developed a system of 613 laws, 365 negative commands and 248 positive laws...By the time Christ came it had produced a heartless, cold, and arrogant brand of righteousness. As such, it contained at least ten tragic flaws:

1. New laws continually need to be invented for new situations.
2. Accountability to God is replaced by accountability to men.
3. It reduces a person's ability to personally discern.
4. It creates a judgmental spirit.
5. The Pharisees confused personal preferences with divine law.
6. It produces inconsistencies.
7. It created a false standard of righteousness.
8. It became a burden to the Jews.
9. It was strictly external.
10. It was rejected by Christ.
