Snake handling is still going on in the United States. This article reports the recent death of a pastor who was bitten by a timber rattlesnake. Apparently the pastor witnessed his own father’s death after a rattlesnake bite, but continued with the practice. I commented on the theological implications of snake handling a few days ago here.
That is to say–they follow an authority structure based on the Bible, their own interpretation and their own tradition–then they try to live by it.
Whether they handle rattlesnakes, discuss Calvinism, build a mega church, swim with alligators, write books about the Myth of God, speak in tongues or go to choral evensong after tea is–theologically speaking– immaterial.
