John wrote that many put faith in Jesus, but because of being afraid of getting expelled from the synagogue, they wouldn't confess him.
John 12: 42
It was a powerful weapon back then, and it's still used today. Even when some want to stop being a Witness, they're lumped in with ones who are unrepentant sinners, and expelled from the congregation.
Wouldn't the Pharisees be proud of many of the things done in the organization today?
