Matthew 23:8-12

But as for you, do not be called Rabbi; for only One is your Teacher, and you are all brothers and sisters.

And do not call anyone on earth your father; for only One is your Father, He who is in heaven.

And do not be called leaders; for only One is your Leader, that is, Christ.

But the greatest of you shall be your servant.

Whoever exalts himself shall be humbled, and whoever humbles himself shall be exalted. Seven Woes
