“Stab, smite, slay!” These are not the words of Bashar al-Assad telling his forces how they should deal with the Syrian rebel movement, or indeed those of any other contemporary political leader, but rather the words of Martin Luther exhorting the German nobility to a harsh response to the peasants' rebellion of 1524–1525. His writings show that he sympathized with many of the peasants' grievances so long as these did not issue in rebellion, but when they turned to force of arms, he responded sternly. This was not a peculiarity of Luther. Consider the following from an English courtier, Thomas Churchyard, writing admiringly of the treatment of Irish rebels in 1579 by Sir Humphrey Gilbert, commander of the English army sent to put down the rebellion: He further tooke this order infringeable, that when soever he made any ostyng [military campaign], or inrode, into the enemies Countrey, he killed manne, woman, and child, and spoiled, wasted, and burned, by the grounde all that he might, leavyng nothing of the enemies in saffetie, whiche he could possiblie waste, or consume.

While the origin and development of the just war tradition until the early modern period blended concerns, ideas, and practices from the moral, legal, political, and military spheres, from the mid-seventeenth century until the mid-twentieth it largely disappeared as a conscious source of moral reflection about war and its restraint. Beginning in the 1960s, however, American theologian Paul Ramsey initiated a recovery of just war thinking in a series of writings applying the principles of discrimination and proportionality, ideas he traced both to Augustinian theology and to natural law, to the debate over nuclear weapons and later to the Vietnam War. Ramsey's work directly engaged both theological and policy debate over military force, initiating lines of reflection that have since developed further and become increasingly institutionalized. This brief essay examines the nature of Ramsey's just war thought and its influence over the last 40 years

Recent just war thought has tended to prioritize just cause among the moral criteria to be satisfied for resort to armed force, reducing the requirement of sovereign authority to a secondary, supporting role: such authority is to act in response to the establishment of just cause. By contrast, Aquinas and Luther, two benchmark figures in the development of Christian thought on just war, unambiguously gave priority to the requirement of sovereign authority as instituted by God to carry out the responsibilities of ensuring a just and peaceful order in the world. On this conception it is the sovereign, in deciding whether to resort to armed force, who must make sure to satisfy the other moral requirements of the jus ad bellum. This paper examines Aquinas and Luther on sovereign authority for use of armed force. Recapturing the importance of this conception is important both for the proper understanding of just war tradition and for working out its implications for such contemporary issues as humanitarian intervention and "regime change."

In contrast to the period when the "Journal of Religious Ethics" began publishing, the study of religion in relation to war and connected issues has prospered in recent years. This article examines three collections of essays providing comparative perspectives on these topics, two recently authored studies of Buddhism and Islam in relation to war, and a compendious collection of texts on Western moral tradition concerning war, peace, and related issues from classical Greece and Rome to the present

What is, or should be, the role of defense in thinking about the justification of use of armed force? Contemporary just war thinking prioritizes defense as the principal, and perhaps the only, just cause for resorting to armed force. By contrast, classic just war tradition, while recognizing defense as justification for use of force by private persons, did not reason from self-defense to the justification of the use of force on behalf of the political community, but instead rendered the idea of just cause for resort to force in terms of the sovereign's responsibility to maintain justice, vindicating those who had suffered from injustice and punishing evildoers. This paper moves through three major stages in the historical development of just war thinking, first examining a critical phase in the formation of the classical idea of just cause as the responsibility to maintain justice, then discussing the shift, characteristic of the modern period, to an idea of sovereignty as connected to the state and the prioritization of defense of the state as just cause for use of force, and lastly showing how this conception of the priority of defense became part of the recovery of just war thinking in the latter part of the twentieth century. The paper concludes by noting recent changes in thought on international law that tend to emphasize justice at the expense of the right of self-defense, suggesting that the roots of just war thinking imply the need for a similar rethinking of contemporary just war discourse
