This paper examines the Long Appeal (Appellatio longa) of 1332 by Bonagratia of Bergamo, O.M. (†1340), situating it within the broader landscape of religious dissent and conflict with papal authority during the pontificate of John XXII (1316-1334). As Procurator of the Order of Friars Minor from 1319, Bonagratia played a crucial role in articulating the Franciscan dissidents' response to papal policies that increasingly sought to redefine the boundaries of orthodoxy, obedience, and institutional identity. Composed in the context of the Franciscan Poverty Controversy and the exile of Michael of Cesena and his brethren at the imperial court of Louis IV Wittelsbach in Munich, the Long Appeal represents a distinctive strategy of opposition. Recently brought to light during my doctoral research—both in its autograph form at the Vatican Apostolic Library and in a late seventeenth-century witness preserved at the Bibliothèque nationale de France in Paris—this text integrates and completes earlier Appeals by introducing new juridical arguments and theological accusations, thereby once again seeking to delegitimize the authority of John XXII. Bonagratia constructs a cumulative case against the pope by identifying a series of alleged heterodox positions, ranging from the denial of Franciscan poverty to John XXII's views on the delayed beatific vision. In doing so, the Appeal illustrates how accusations of heresy could function as a means of contesting authority and preserving communal identity in moments of institutional crisis. By analyzing the Long Appeal as a form of negotiated yet confrontational dissent, this paper contributes to the panel's broader aim of exploring how religious actors under John XXII positioned themselves vis-à-vis papal authority, and how theological, ecclesiological, and political conflicts became deeply intertwined in the early fourteenth century.
