Matthew 23:8-12

8“Don’t let anyone call you ‘Rabbi,’ for you have only one teacher, and all of you are equal as brothers and sisters.

9And don’t address anyone here on earth as ‘Father,’ for only God in heaven is your Father.

10And don’t let anyone call you ‘Teacher,’ for you have only one teacher, the Messiah.

11The greatest among you must be a servant.

12But those who exalt themselves will be humbled, and those who humble themselves will be exalted.
