This article explores how scholastic just war theories and concepts of theological counsel became increasingly problematic in the run-up to the Thirty Years War. It identifies increasing conceptual difficulties due to probabilism, religiously inspired contemporary warfare, and skeptical readings of the Old Testament. Such theoretical problems were exacerbated in the context of the struggle for European hegemony with French pamphleteers starting to ridicule theological discourse in order to denounce Spanish dominance, in particular during the Valtelline crisis. Scholastic just war traditions were so fundamentally discredited that the former royal confessor Caussin was eventually forced to abandon them. Instead he tried to recover theological authority and to safeguard the essence of scholastic just war teachings through a pacified reading of the Old Testament. Though ultimately unsuccessful, his adaptations bear witness to profound changes in the appreciation of the scholastic heritage as well as in the decline of moral theology for political decision-making.

Anthony Pagden (Cambridge, 1987), 79-98, here 98. This is mostly seen as an effect of the growing influence of Grotius’s “secular” concepts which were, however, highly indebted to Thomism, see John Bossy, “Practices of Satisfaction, 1215-1700,” in Retribution, Repentance, and Reconciliation: Papers Read at the 2002 Summer Meeting and the 2003 Winter Meeting of the Ecclesiastical History Society, ed.
