Philippians 3:5-6

3:5 I was circumcised on the eighth day, from the people of Israel and the tribe of Benjamin, a Hebrew of Hebrews. I lived according to the law as a Pharisee. ¹  3:6 In my zeal for God I persecuted the church. According to the righteousness stipulated in the law I was blameless.

[3:5]  ¹ sn A Pharisee was a member of one of the most important and influential religious and political parties of Judaism in the time of Jesus. There were more Pharisees than Sadducees (according to Josephus, Ant. 17.2.4 [17.42] there were more than 6,000 Pharisees at about this time). Pharisees differed with Sadducees on certain doctrines and patterns of behavior. The Pharisees were strict and zealous adherents to the laws of the OT and to numerous additional traditions such as angels and bodily resurrection.
