Preachers ain't done 'til the snakes are back in the box

The book is about the Pentecostal churches in the southeastern United States that use venomous snakes during worship to affirm their faith to themselves and to other church members. In addition to the book's overall description of the phenomenon, two pastors have also participated by sharing their faith. Of course, the book is also about the snakes they use, snakes always play the main role in my books. How are the snakes affected by being taken from the wild and handled during church services?
