Matthew 23:27 [Amplified Bible]
"Woe to you, scribes and Pharisees, pretenders (hypocrites)!"
There are many different masks that people wear. The most common mask is the over-confident, self-centered, self-righteous mask (aka Pharisee). This is what comes to mind most often when we think of Pharisees. They spend time cleaning the outside of the cup, but they are unaware that their insides are filthy.
A less commonly identified is the under-confident, self-less, self-doubting mask. These people go with the crowd because they aren't willing to risk the status they have with their friends, family, coworker, etc. They put this mask on and act like everything is ok because they want to belong to something to someone, even if they can't be honest, truthful or themselves.
I believe churches are filled with both. However, the second group is more likely to be set free. I know this because of an Elder brother (the Pharisees) who wears the first Mask end up angry refusing to enter God's feast. And then their is a Pharisee named Nic who wears the second mask who comes to Jesus at night to ask about eternal life.
Maybe you're wearing a mask and you need to shed it.
