Jesus' over the top sayings - dads and teachers

In Matthew 23, Jesus is ripping on religious leaders. In one part he says,

8 Don't ever let anyone call you 'Rabbi,' for you have only one teacher, and all of you are on the same level as brothers and sisters. 9 And don't address anyone here on earth as 'Father,' for only God in heaven is your spiritual Father. 10 And don't let anyone call you 'Master,' for there is only one master, the Messiah. v 11 The greatest among you must be a servant. 12 But those who exalt themselves will be humbled, and those who humble themselves will be exalted. 

Taken literally, as some of us have, this results in finger pointing towards others in Christendom who do use the appellation "Father" for their leaders. At the same time, we ignore the fact that we'll call some of our leaders, "Teachers." I wonder if there are some who won't even refer to their biological male parent as "Father." Maybe they call them by their first names. But one of Jesus' favorite rhetorical methods is hyperbole. In other places he tells us to cut off our hands or pluck our eyes out if they cause us to sin. Even the hard core literalists among us usually appeal to rhetoric at those verses.

What is Jesus' point then?

He was warning people about the religious leaders, calling them hypocrites, who do not practice what they teach, so I think the implied qualifier for Rabbi and Father is "perfect." Do not accord infallibility to any earthly person. We are all broken. He doesn't want us to trust everything that spews from those we entrust with authority. Check it with the only perfect teacher and father.
