Baltimore police are in the process of arresting a 58-year-old man who argued with his son in church about the 19-year-olds refusal to take his hat off. The father then proceeded to stab his son in the left buttock.
The father then fled. This strikes me as a somewhat curious lesson about proper etiquette in church. Hats are strictly prohibited while knives are permissible. Of course, the father could have packed some real firepower in Arkansas where you are allowed to lock and load for Jesus.
The Bible does promise joy from discipline: Discipline your son, and he will give you peace, he will bring delight to your soul. ~ Proverbs 29:17. However, it also takes a dim view of the use of potentially lethal force in the discipline of children: Discipline your son, for in that there is hope; do not be a willing party to his death. ~ Proverbs 19:18
