In my previous post, I discussed theologians who offered interpretations of the doctrine of the two swords before the Second Vatican Council. While some hierocrats believed that the pope’s two swords made him lord of the world, Vitoria, Bellarmine, and Suarez argued that popes had indirect power in temporal matters. Papal power was only indirect because temporal rulers were “supreme in their own order.” These theologians also believed that temporal rulers derived their authority from the political community, not from the pope. Nonetheless, for spiritual ends, the pope could use temporal authority, even to the point of deposing rulers in certain circumstances. (I mentioned the deposing power in the section on Suarez. Perhaps I could have mentioned it a few more times as a way of clarifying the extent of this “indirect power” in the thought of Vitoria, Bellarmine, and Suarez, even though I was focused on what they said about the “two swords.”)

While some seventeenth-century contemporaries of Bellarmine and Suarez and modern scholars see the controversy between the hierocratic position and this idea of “indirect power” as a distinction without a difference, Bellarmine faced opposition from some in the Roman Curia for his idea. So, the debate certainly mattered at that time.

We should not ignore this seventeenth-century debate. While my previous post indicated that the “two swords” doctrine was interpreted in different ways long before Vatican II, we should not forget that twentieth-century challenges to the temporal power of the papacy (whether direct or indirect) saw Bellarmine (and not the hierocrats) as the major challenge. My goal here is not to oppose (or defend) Bellarmine, nor is it to endorse (or challenge) the twentieth-century arguments that follow. I hope that these passages might be of interest and useful for future discussion.
