PTG Author on King Saul and Consulting Mediums

I am reviewing the reign of King Saul and various other things, and so when I noticed that posted “Why Did God Kill King Saul and Turn the Kingdom over to David?” on the Preaching the Gospel blog, I had to read it.  He asks why God caused Saul to die in battle, and then writes:

There was more than one reason, but one of the reasons, according to this passage, is that Saul consulted a medium for guidance.

Do some of us in the Church of God do this?

This is not a frivolous question, as reading the rest of his article reveals.
