On the fifteenth of April, 1521, the University of Paris, whose opinion respecting Luther's tenets the entire Christian world had for two years been anxiously expecting, pronounced its solemn decision. It condemned the writings of the German monk to the flames, on the ground that they were seductive, insulting to the hierarchy, contrary to Scripture, and schismatic. It likened his latest production, _De Captivitate Babylonica_, to Alcoran. It branded as preposterous the notion that God had reserved the discovery of what is needful to the salvation of the faithful for Martin Luther to make; as though Christ had left his spouse, the Church, so many centuries, and until now, in the darkness and blindness of error. Such sentiments as he uttered were a denial of the first principles of the faith, an unblushing profession of impiety, an arrogance so impious that it must be repressed by chains and censures--nay, by fire and by flame, rather than refuted by argument.[234] A long list of heretical propositions selected from Luther's works was appended.[235] [Sidenote: Melanchthon's defence.] In the month of June following, Melanchthon replied to the Sorbonne's condemnation. He declared that, could the great Gerson and his illustrious associates and predecessors rise from the dead, they would fail to recognize in the present race of theologians their legitimate offspring, and that they would deplore the misfortune of the university as well as of the whole of Christendom, in that sophists had usurped the place of theologians, and slanderers the seat of Christian doctors. As for the silly letter prefixed to the decree, the reformer wrote, it is a feeble production full of womanish fury: "He pretends to the sole possession of wisdom. He contemns us. He is a Manichæan, a Montanist; he is mad. Let him be compelled by fire and flame." Who could refrain from derisive laughter at the unmanly and truly monkish weakness of such threats?[236] [Sidenote: Regency of Louise de Savoie.]
