The Florentines now prepared for war, by raising money and collecting as large a force as possible.  Being in league with the duke of Milan and the Venetians, they applied to both for assistance.  As the pope had proved himself a wolf rather than a shepherd, to avoid being devoured under false accusations, they justified their cause with all available arguments, and filled Italy with accounts of the treachery practiced against their government, exposing the impiety and injustice of the pontiff, and assured the world that the pontificate which he had wickedly attained, he would as impiously fill; for he had sent those whom he had advanced to the highest order of prelacy, in the company of traitors and parricides, to commit the most horrid treachery in the church in the midst of divine service and during the celebration of the holy sacrament, and that then, having failed to murder the citizens, change the government, and plunder the city, according to his intention, he had suspended the performance of all religious offices, and injuriously menaced and injured the republic with pontifical maledictions.  But if God was just, and violence was offensive to him, he would be displeased with that of his viceregent, and allow his injured people who were not admitted to communion with the latter, to offer up their prayers to himself.  The Florentines, therefore, instead of receiving or obeying the interdict, compelled the priests to perform divine service, assembled a council in Florence of all the Tuscan prelates under their jurisdiction, and appealed against the injuries suffered from the pontiff to a future general council.
