St. George and the Dragon is a strange but popular tale. We actually know very little about George but it has not stopped us from heaping accolades upon this martyr - as we should upon all martyrs for the Faith. We live the life of Christ on their merits.
Saint George was a man who abandoned one army for another: he gave up the rank of tribune to enlist as a soldier for Christ. Eager to encounter the enemy, he first stripped away his worldly wealth by giving all he had to the poor. Then, free and unencumbered, bearing the shield of faith, he plunged into the thick of the battle, an ardent soldier for Christ.
Clearly what he did serves to teach us a valuable lesson: if we are afraid to strip ourselves of our worldly possessions, then we are unfit to make a strong defense of the faith.
As for Saint George, he was consumed with the fire of the Holy Spirit. Armed with the invincible standard of the cross, he did battle with an evil king and acquitted himself so well that, in vanquishing the king, he overcame the prince of all wicked spirits, and encouraged other soldiers of Christ to perform brave deeds in his cause...let us not only admire the courage of this fighter in heaven’s army but follow his example. Let us be inspired to strive for the reward of heavenly glory, keeping in mind his example, so that we will not be swayed from our path, though the world seduce us with its smiles or try to terrify us with naked threats of its trials and tribulations.
