"Quasi haereticus”. Lo scisma nelle riflessione degli inquisitori dell'età moderna

The article discusses the problem of the relationship between schism and heresy through the practice and the legal and theological reflection of the inquisitors, from the late Middle Ages to the end of the Seventeenth century, in a time when the papal primacy and the obedience to Rome are strengthened. In particular, it reconstructs the action lines of the Roman Inquisition against the Greeks under his jurisdiction (in Venice and its domains, in Livorno, in Ancona, in Southern Italy and in Malta), and the strategy adopted by the Curia from the secretariat of Cardinal Giulio A. Santoro, chief Inquisitor and at the same time head of the Congregation of the Greeks, onward. Secondly, the research analyzes the way in which the relationship between schism and heresy was discussed in the manuals for the inquisitors, by the end of the Fifteenth century until the writings of Francesco Albizzi, who took issue with Paolo Sarpi and commented the decrees of the Holy Office and the Propaganda Fide on the complex problem of the communicatio with the Orthodox.
