[...] They [scribes and Pharisees] love to have the
place of honor at banquets and the best seats in the synagogues,
and to be greeted with respect in the marketplaces, and to have
people call them rabbi. But you are not to be called rabbi, for
you have one teacher, and you are all students. And call no one
your father on earth, for you have one Father--the one in heaven.
Nor are you to be called instructors, for you have one instructor,
the Messiah. The greatest among you will be your servant. All
who exalt themselves will be humbled, and all who humble themselves
will be exalted.
