This paper argues that the record of theological dissent at Trent and Vatican I are positive and fruitful sources of theological reflection on the sensus fidelium. Not only do these “minority” voices (minority in the literal sense of opposing a majority group or opinion) help us to accurately interpret the drafts and final documents of these councils, but these minority figures can sometimes preserve the sensus fidelium through their calls for various concessions from the majority.
First, I revisit Trent's decree on Scripture (1546). Due to the interventions of two Italians (Nacchianti, the Bishop of Chioggia, and Bonuccio, the General of the Servites), the question of the relationship between scripture and tradition was left open – that is, the “two‐source” partim‐partim theory was not dogmatically enshrined. This was an important episode wherein a tiny minority gained a critical concession. I argue that this minority intervention bore fruit not only in a final Tridentine document that better echoed the faith of the ages, but also bore fruit centuries later at Vatican II in Dei verbum.
Second, I argue that the minority at Vatican I protected the Church from extreme ultramontanism. This relatively large and intellectually powerful minority, many of them rooted in Gallicanism, played a key role in tempering a dogmatic proclamation that was further balanced and interpreted a century later in Lumen gentium and Christus Dominus.
I conclude by suggesting theologians should look for ways in which the minority at Vatican II could serve future generations of Catholics in unforeseen ways.
