A 49 year old Maitland-Newcastle Diocese priest faced a committal hearing on 18 child sex charges in Newcastle Local Court on Tuesday.
The Crown withdrew four charges before the hearing, ABC reports.
The charges date back to the 1980s with offences allegedly committed in Muswellbrook, Maitland, Cessnock and Windale.
A 38-year-old alleged victim giving witness says he was touched by the priest on his genitals during a self defence lesson at a Maitland church complex when he was eight years old.
He told the court he was frightened after seeing O'Hearn's facial expressions change, the report said. He said he now understands that look to be one of lust, saying the incident has never left him.
