I raise the question because if we are to distinguish Burton's class from VPW's class, we cannot ignore the fact that VPW endorsed Burton's class. If he thought there was anything wrong with it, he would have said so (and if it was the late 70s, they most certainly would have listened).
If Burton was wrong about what VPW thought the manifestations should be, then VPW curiously did not call him on his error. And that's fine. No one said VPW was perfect. I mean, it's not like he felt the holy spirit field was an important area of study or something.
