As television evangelist George Vandeman looked on, his son surprised a Ventura courtroom by admitting that he stabbed the clergyman in the back last month in Thousand Oaks. Ronald L. Vandeman, 43, described by a prosecutor as suffering from schizophrenia, pleaded guilty to assault with a deadly weapon as he prepared to face his father during a preliminary hearing stemming from the April 11 knife attack. George Vandeman, 68, is a Seventh-day Adventist Church clergyman who has been host of “It Is Written” since originating the religious TV show 29 years ago.
