The Purpose Of The Order Was Now The Defense And Propagation Of The Faith.

After his death in 1556, Ignatiusof Loyola was regularly presented in contrast to Martin Luther, and the Jesuits themselves were the prime culprits for this portrayal. Viewed in the context of post Tridentine counterattacks, such a rendering is understandable. Moreover, the military metaphors that Ignatius himself used in much of his writing, while ultimately rooted in his previous chivalric fascinations, corresponded nicely to the image of Ignatius and the Jesuits as the shock troops of the Counter-Reformation. Of course such a view of the Jesuits has some truth to it. Jesuits participated at Trent (though in a more peripheral manner) and were instrumental in implementing the decrees of the Council. Robert Bellarmine was one of the most distinguished persons of the era with his attacks on Protestantism and his defense of Catholic theology. Toward the end of his life, Ignatius himself was more active in the fight against the Lutherans. He frequently communicated with Peter Canisius, who was on the frontlines of the conflict in Germany, about his growing awareness for this aspect of the Society's mission. In 1550, Ignatius revised the bull that established the Jesuits, stating that the purpose of the order was now the defense and propagation of the faith.
