Matthew 23:8-12

“Don’t let anyone call you ‘Rabbi,’ for you have only one teacher, and all of you are equal as brothers and sisters. And don’t address anyone here on earth as ‘Father,’ for only God in heaven is your Father. And don’t let anyone call you ‘Teacher,’ for you have only one teacher, the Messiah. The greatest among you must be a servant. But those who exalt themselves will be humbled, and those who humble themselves will be exalted.
