“Innocent, bishop, servant of the servants of God, in the presence of the holy council, for an everlasting record. Raised, though unworthy, to the highest point of the apostolic dignity, by the will of the divine majesty, we ought to exercise a watchful, diligent and wise care of all Christians, to examine with close attention the merits of individuals and to weigh them in the balance of prudent deliberation, so that we may raise by suitable favours those whom a rigorous and just examination shows to be worthy, and depress the guilty with due penalties, weighing always the merit and the reward in a fair scale, repaying to each the amount of penalty or favour according to the nature of his work.”  Pope Innocent IV, First Council of Lyon, Bull Deposing Emperor Frederick II
