‘The sixth commandment forbids murder. The ethical theology that lies behind this prohibition is the fact that all men and women have been created in the image of God (Gen 1:26-26; 9:6). While Hebrew possesses seven words for killing, the word used here, rasah, appears only forty-seven times in the OT. If any one of the seven words could signify “murder” where the factors of premeditation and intentionality are present, this is the verb… Without exception, however, in later periods (e.g. Ps 94:6; Prov 22:13; Isa1:21; Hos 4:2; 6:9; Jer 7:9) it carries the idea of murder with intentional violence. Every one of these instances stresses the act or allegation of premeditation and deliberateness –and that is what is at the heart of this verb. Thus this prohibition does not apply to beasts (Gen 9:3), to defending one’s home from night-time burglars (Ex22:2), to accidental killings (Deut 19:5), to the execution of murderers by the state (Gen 9:6); or to involvement with one’s nation in certain types of war as illustrated by Israel’s history. It does apply, however, to self-murder (i.e. suicide), to all accessories to murder (2 Sam 12:9), and to those who have authority but fail to use it to punish known murderers (1 Kings 21:19)’ Kaiser, Walter C., Exodus, in Gaebelein, Frank E., ed., EBC, vol. 1, pp. 424f.
‘To kill in the name of Christ and in order to advance the kingdom of Christis expressly forbidden by Jesus (Mt 26:52, 53). Yet sometimes we have to take up the sword in order to preserve life, and this is permitted in the Bible but as something that pertains to the passing aeon, the world of sin and darkness, not to the new age of the kingdom of God. Since we belong to the old age as well as to the new, we act in two roles: as responsible citizens of the state, which can only maintain itself by force, and as ambassadors of the kingdom of Christ, which maintains itself solely by works of faith and love. The ethic of Jesus expressed in the so-called Sermon on the Mount was given to disciples, not to nations. If the radical ethic of nonresistance were applied directly to nations, it would mean the end of all civil government. Yet the church, which is under this higher command, can be a guide to the nations. It is the moral monitor or the conscience of the state. In Romans 13 the power of the state to wield the sword is expressly acknowledged by Paul; at the same time, the sixth commandment is vigorously reaffirmed. The principle of nonresistance or no retaliation can be a goal or ideal in the social arena, but never a political strategy.’ (Bloesch, Donald, Freedom for Obedience (NY: Harper and Row, 1987), 292-293
