The book of Proverbs is often used, it would seem, to justify the claim that a true Christian approach to raising children must invariably include the use of corporal punishment (see, for example, Prov 13:24; 22:15; 23:13–14; 29:15)...
Christians talk about violence but when someone wants to practice it, they are ridiculed. It is very hypocritical.
