My definition of self defense is not having hate or murder in your heart.
The fear and survival instinct causes someone to defend himself.
Murder and killing in justified self defense are two totally different things as far the denomination and stances of Christianity on this issue are concerned.
Just protect your family and yourself.
Keep religion and self defense separate then you will be o.k.
Don't make it harder or confusing. Keep it simple.
I think SL was referring to the fact that the commandment should read 'murder' as 'kill' is a literal mistranslation of the original, I don't think he was getting into a theological argument.
Brother John you may take the Bible literally, I don't know, but it's actually my people's history and writings, you're welcome to enjoy it of course but do remember its Jewish origins and the fact your Jesus was Jewish with Jewish thinking, mores and morals, he was also targeting his work towards Jews. The whole message thing got diverted off it's course when the Christians got hold of it not to it's betterment I should add.
