So who were the Pharisees?
Around the time of the New Testament there were three main religious movements or societies in Judaism. They were the Pharisees, the Sadducees (sometimes also called the Herodians), and the Essenes. The Sadducees were associated more with royalty and the upper classes while the Pharisees were more connected to the the poor and lower classes. The Sadducees taught people to go strictly by the text of the Torah, while the Pharisees taught not only the text of the Torah, but also the interpretations made by the Rabbis. They believed that the laws handed to Moses on Mt. Sinai were the written book of the Torah and the second book was the oral interpretations.
Over time the Sadducees and Essenes lost their power and later their followers, leaving the Pharisees as the main source of religious instruction. The Pharisees wanted to have the Jews live lives apart from the heathens that surrounded them, to not take foreign wives, and to keep themselves pure.
Law versus Love
The issue that Jesus had with the Pharisees was one of law versus love. The Pharisees taught and believed very strongly that if they followed the word of God to the letter, not only the written laws of the Torah, but also the much more extensive oral laws of the Rabbis, then they could guarantee their places in heaven. On the other hand, Jesus taught that God’s lovewas paramount and the strict adherence to the Rabbinical interpretations of the law were not the intent of God.

In Matthew 5:20 Jesus said, “For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.”
Again in Matthew 15:3-6 He answered them, “And why do you transgress the Commandment of God for the sake of your tradition? For God commanded, ‘Honor your father and your mother,’ and, ‘He who speaks evil of father or mother, let him surely die.’ But you say, ‘If any one tells his father or his mother, What you would have gained from me is given to God, he need not honor his father.’ So, for the sake of your tradition, you have made void the Word of God.”
Conclusion
The Pharisees had become so wrapped up in what they were doing and avoiding to maintain their holiness in the eyes of God, they lost sight of the will of God. The Pharisees, unlike the Sadducees, believed in the coming of the Messiah and resurrection after death. But when confronted by Jesus, they could not believe that he was the Savior and banded together to work for hisdeath, thus proving what he had been saying about them all along.
