Can Christians be prejudiced against other Christians?

Romans 14:10So why do you condemn another believer? Why do you look down on another believer? Remember, we will all stand before the judgment seat of God.

Galatians 3:28There is no longer Jew or Gentile, slave or free, male and female. For you are all one in Christ Jesus.

Colossians 3:14Above all, clothe yourselves with love, which binds us all together in perfect harmony.

Christians are human, and just like everyone else they can exhibit their sinful human nature. But Christians are supposed to be led and controlled by the Holy Spirit and must be careful not to let feelings of prejudice control their thoughts and actions. They, of all people, should understand that God created all people and that he loves and values all people equally.
