The man accused of stabbing his father several times in the neck said he was "moved by a message" before the incident.
Ethan Buckley, 21, was arraigned in Warren County, Kentucky Monday morning following the stabbing at Hillvue Heights Church in Bowling Green.
Witnesses said Buckley stabbed his father during altar call at the 9:30 am service.
A police citation revealed Buckley had thoughts of killing his father and admitted to using a pocket knife to stab him.
The report also said Buckley tried to cut his father's jugular vein so it would be painless.
Buckley's bond was set at $500,000 and his preliminary hearing is scheduled on Friday morning.
The stabbing incident is a reason why experts say churhces must have a security plan in place.
"Just because it's a church doesn't mean it's totally free of incidents," Warren Smith, a firearm instructor told NewsChannel 5. "It's better to be prepared and know how to react."
Smith is an instructor for Agape Tactical, LLC, a team that specializes in handgun carry permit trainings, pistol and rifle tactical classes, emergency response and range safety classes and church trainings.
"More churches are wanting training," Smith added.
Some of the instructors also are involved in their church's security team. Dawn Bradley leads her Spring Hill area church's safety team by offering training.
"Our team has processes in place that start with the street and go to the parking lot, the lobby and the sanctuary," Bradley said.
Bradley did not want to reveal her church's name and exact tactics for protection but she said her team is ready for any threat or emergency.
Some of the members are armed but Bradley urged that they have different methods to prevent using full force.
"The greatest act of love is to protect and care for people so we don't want to hurt anybody."
