Exsurge Domine

Exsurge Domine (Latin Arise O Lord) is a papal bull issued on 15 June 1520 by Pope Leo X in response to the teachings of Martin Luther which opposed the views of the papacy. It censured forty one propositions extracted from Luther's 95 theses and subsequent 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 lashing out at the papacy and by publicly burning a copy of the bull on 10 December 1520.
