Martin Luther on Homicide

“Through violence you may murder a liar but you can't establish truth. Through violence you may murder a hater, but you can't murder hate. Darkness cannot put out darkness. Only light can do that.”

“You must not murder.(Exodus 20:13) Q. What does this mean? A. We should fear and love God so that we may not hurt or harm our neighbor in his body, but help and befriend him in every bodily need [in every need and danger of life and body].”

“We have now completed both the spiritual and the temporal government, that is, the divine and the paternal authority and obedience. But here now we go forth from our house among our neighbors to learn how we should live with one another, every one himself toward his neighbor. Therefore God and government are not included in this commandment nor is the power to kill, which they have taken away. For God has delegated His authority to punish evil-doers to the government instead of parents, who aforetime (as we read in Moses) were required to bring their own children to judgment and sentence them to death. Therefore, what is here forbidden is forbidden to the individual in his relation to any one else, and not to the government.”
