Matthew 23:8-12

But none of you should be called a teacher. You have only one teacher, and all of you are like brothers and sisters. Don't call anyone on earth your father. All of you have the same Father in heaven. None of you should be called the leader. The Messiah is your only leader. Whoever is the greatest should be the servant of the others. If you put yourself above others, you will be put down. But if you humble yourself, you will be honored.
