“God said, "Thou shalt not kill" - does the theft of a little money make it quite all right for us to do so? If it's said that this commandment applies only to illegal killing, what's to prevent human beings from similarly agreeing among themselves to legalize certain types of rape, adultery, or perjury? Considering that God has forbidden us even to kill ourselves, can we really believe that purely human arrangements for the regulation of mutual slaughter are enough, without any divine authority, to exempt executioners from the sixth commandment? Isn't that like saying that this particular commandment has no more validity than human laws allow it? - in which case the principle can be extended indefinitely, until in all spheres of life human beings decide just how far God's commandments may conveniently be observed.”
