How does Christianity feel about mediums?

So far as I can perceive through my medium and otherwise, your present church systems are wrong. 

I do not like them. 

Get a church together in the name of Jesus, and the same gifts that were free to the first churches would become free to them, and then you would see all flock to them. 

Depend upon it, these wonderful gifts are as much required now as at the first.

—Hafed, Prince of Persia
