Yea I know,I did the very same thing.Watched alot of TBN too.That's where I saw Copeland and Hinn,as well as Jan and Paul.I remember asking God if I accepted him,did I have to act like those fools!
Graciously he said no. ;)
I have read that Copelnad is not even a trinitarian..I would have to source it..
We are told to "try the spirit" ..I think that is because God know like a baby sticks his finger in the socket ..Christian babes just soak in every thing that "sounds" christian..no discernment...that come with age
