Christianity Today Magazine has an article about Corporal Punishment in their January 2012 Issue which you might want to purchase. When and if they post it online, I will post a link to it. This article mentions Hana Alemu “Williams”, Lydia Schatz and Sean Paddock and the influence of To Train Up A Child by Michael and Debi Pearl. It then goes on to discuss the spanking controversy and Professor William Webb’s book, Corporal Punishment In The Bible.
There is a discussion of the article on the Gentle Christian Mothers forum which contains a small quote.
Update: It has been posted here.
