Matthew 23:6-10

They love the best places at feasts, the best seats in the synagogues, greetings in the marketplaces, and to be called by men, ‘Rabbi, Rabbi.’ But you, do not be called ‘Rabbi’; for One is your Teacher, the Christ, and you are all brethren. Do not call anyone on earth your father; for One is your Father, He who is in heaven. And do not be called teachers; for One is your Teacher, the Christ.
