'Party' in the Bible

But some believers from the party of the Pharisees stood up and said, "The gentiles must be circumcised and ordered to keep the Law of Moses."

There was a great deal of shouting until some of the scribes who belonged to the party of the Pharisees stood up and argued forcefully, "We find nothing wrong with this man. What if a spirit or an angel has spoken to him?"

They have known for a long time, if they would but testify to it, that I lived as a Pharisee, adhering to the standards of our strictest religious party.

Until some men arrived from James, he was in the habit of eating with the gentiles, but after those men came, he withdrew from the gentiles and would not associate with them any longer, because he was afraid of the circumcision party.

Now a mediator involves more than one party, but God is one.
