The paper investigates the postconciliar "normalization" of Vatican II by mapping the standardization of ecclesiological language in the Holy See's magisterium from 2000 to 2025. It classifies formulaic patterns that describe papal-episcopal relations («cum N.», «sub N.», «cum N. et sub N.») and their main competitors («in communione cum N.», «sub auctoritate N.», etc.), as well as the principal referent-families (petrine, pontifical, sedeological…). The results highlight shifting preferences across three pontificates, including the growing stabilization of «cum Petro et sub Petro» as a condensed ecclesiological "signature".
