Why should a church have bishops?

 I believe in bishops.  I've had both really good and really bad experiences of Episcopal oversight, but experience is not what drives my belief system: the Bible interpreted through the historic church is.  That is why I believe in bishops.  

I know that this is an active topic of discussion among Methodists - and the Global Methodist Church in particular will decide later this year about whether to accept bishops at all and, if so, what sort of bishop it will be.

In this video I explain some of the reasons (there are others) why I think bishops are essential for the flourishing and especially for the unity of the whole church, and the congregations within it.
