St. Michael is the model of the Christian warrior because of the fortitude which he showed by casting into hell the legions of damned spirits. He is the warrior of God who will not tolerate the divine Majesty to be challenged or offended in his presence, and who is ready to wield the sword at any time in order to crush the enemies of the Most High. He teaches us that it is not enough for a Catholic to behave well: it is also his duty to fight evil. And not just an abstract evil, but evil as it exists in the ungodly and in sinners.
For St. Michael did not cast evil into hell as a principle, a mere conception of the intellect, nor are principles and concepts susceptible to be burned by eternal fire. It was Lucifer and his minions that the Champion of the Almighty cast into hell, as he hated the evil that existed in them and which they loved.
We live at a time of profound religious liberalism. Few Christians have an inkling that they belong to a Church militant, as militant on earth as St. Michael and the faithful Angels were militant in heaven. We also should know how to crush the insolence of wickedness. We too must tenaciously counter the adversary by attacking him and rendering him powerless.
In this struggle, St. Michael should not just be our model but our help. The fight between St. Michael and Lucifer has not ceased but continues throughout the ages. He helps all Christians in the battles they wage against the power of darkness.
