Kevin Swanson is an ordained pastor in the Orthodox Presbyterian Church. You can hear his radio show on the Sermon Audio website. I can assure you that Kevin Swanson is well-known in home school circles and in the family-integrated worship movement. He frequently shared a stage with Doug Phillips of Vision Forum before Doug Phillips' resignation.
Even when I agree with Kevin Swanson, his over-the-top dogmatic style is hard to take. I haven't seen Frozen but it wouldn't surprise me if Kevin Swanson's criticism is misguided.
Well I do know this... fling around hell fire and even if you are a million light years off base to the scripture, people will watch you in riveted fascination.
It really infantilizes the concept of ministry. IMHO. It also tends to get my goat and maybe I shouldn’t let it. But hell fire is at best a kick start for the stubborn. It isn’t what makes a life of faith carry on.
