Churchmouse has posted an extensively researched look at Spiritual and Physical Abuse in Christian child abuse: more works-based carnality. This is a long piece and well worth the time it will take to read it.
Under Much Grace has discovered information of a case from 2002 of a boy being “disciplined” into Renal Failure. Disclaimer: this is not the case of parents disciplining their child, this is a case of 22 yr old men disciplining a young boy for way too long and ending up in jail. One later wrote a book about his jail experience and how he continued to serve the Lord in jail. The whole story is very disturbing on many levels.
She also has an article exposing the dangerous teachings of Ron Williams of Hepzibah House. He is very clear in his teachings, actually using the term, “beat,” and advocating starting in infancy. Here is a quote:
As soon as the child begins to express his own self-will (and this occurs early in life) that child needs to receive correction. My wife and I have a general goal of making sure that each of our children has his will broken by the time he reaches the age of one year. To do this, a child must receive correction when he is a small infant.
