This well-known carol, drawing on the legend of St. Wenceslaus, tells the moving story of a generous king going to great effort to help one of his poor subjects.
There is a wonderful edition of the carol in children's book form, which I enjoy reading (and singing) to my children each Christmas season.
In his homily today, Pope Benedict, who is currently visiting the Czech Republic, held up Wenceslaus as a model of holiness:
...This morning, we are gathered around the altar for the glorious commemoration of the martyr Saint Wenceslaus, whose relics I was able to venerate before Mass in the Basilica dedicated to him. He shed his blood in your land, and his eagle, which – as the Cardinal Archbishop has just mentioned – you chose as a symbol for this visit, constitutes the historical emblem of the noble Czech nation. This great saint, whom you are pleased to call the “eternal” Prince of the Czechs, invites us always to follow Christ faithfully, he invites us to be holy. He himself is a model of holiness for all people, especially the leaders of communities and peoples. Yet we ask ourselves: in our day, is holiness still relevant? Or is it now considered unattractive and unimportant? Do we not place more value today on worldly success and glory? Yet how long does earthly success last, and what value does it have?
The last century – as this land of yours can bear witness – saw the fall of a number of powerful figures who had apparently risen to almost unattainable heights. Suddenly they found themselves stripped of their power. Those who denied and continue to deny God, and in consequence have no respect for man, appear to have a comfortable life and to be materially successful. Yet one need only scratch the surface to realize how sad and unfulfilled these people are. Only those who maintain in their hearts a holy “fear of God” can also put their trust in man and spend their lives building a more just and fraternal world. Today there is a need for believers with credibility, who are ready to spread in every area of society the Christian principles and ideals by which their action is inspired. This is holiness, the universal vocation of all the baptized, which motivates people to carry out their duty with fidelity and courage, looking not to their own selfish interests but to the common good, seeking God’s will at every moment...
