Exsurge Domine

is a papal bull promulgated on 15 June 1520 by Pope Leo X. It was written in response to the teachings of Martin Luther which opposed the views of the Catholic Church. The bull censured forty-one propositions summarised from Luther's writings, and threatened him with excommunication unless he recanted within a sixty-day period commencing upon the publication of the bull in Saxony and its neighboring regions. Luther refused to recant and responded instead by composing polemical tracts rebuking the papacy, and by publicly burning a copy of the bull on 10 December 1520. As a result, Luther was excommunicated in 1521. History The historical impetus for this bull arose from an effort to provide a decisive papal response to the growing popularity of Luther's teachings. Beginning in January 1520, a papal consistory was summoned to examine Luther's fidelity to Catholic teachings. After a short time, it produced a hasty list of several perceived errors found in his writings, but Curial officials believed that a more thorough consideration was warranted. The committee was reorganized and subsequently produced a report determining that only a few of Luther's teachings could potentially be deemed heretical or erroneous from the standpoint of Catholic theology. His other teachings perceived as problematic were deemed to warrant lesser degrees of theological censure, including the designations "scandalous" or "offensive to pious ears".
