Matthew 23:8-12

“But you must not be called ‘Teacher,’ because you have only one Teacher, and you are all brothers and sisters together. And don’t call any person on earth ‘Father,’ because you have one Father, who is in heaven. And you should not be called ‘Master,’ because you have only one Master, the Christ. Whoever is your servant is the greatest among you. Whoever makes himself great will be made humble. Whoever makes himself humble will be made great.
