There is that famous line from Mel Brooks's movie History of the World: Part I, "It's good to be king!" Being king brings up beautiful imagery of elaborate court ritual, absolute authority, and feasting; sounds a lot like the institutional church! But Jesus' words to Pilate betray this image of opulence. When asked about his kingdom, Jesus replies "My kingdom does not belong to this world" (New American Bible). Another translation has it as "My kingdom is not of this world"(New International Version). The sense of Jesus' reply is that his kingdom is neither the kingdom of Rome nor the kingdom envisioned by the religious authorities; both groups lose.
The Solemnity of Christ the King that embraces Jesus as king is relatively new. It was established in 1925 to counter what the Church saw as an increasing tendency to worship human wisdom and power, which was loosely defined as modernism. Later, positioning the solemnity at the end of the Church's liturgical year in 1969 further enhanced its standing as the summit of Christ's rule and, implicitly, the Church as Christ's kingdom.
However, the songs and imagery associated with this celebration often blunt the irony of Christ as king. The common representation is a resurrected, non-bloody Jesus hovering (rather than being nailed) on the cross. The image of Christ as king is ironic because he is the king with a crown of thorns a procession of humiliation, and a knightly court of cowards. It seems as St. Paul writes in his letter to the Corinthians, "For the message of the cross is foolishness to those who are perishing, but to us who are being saved, it is the power of God."
The ironic image of Jesus as king nailed to the cross speaks of a different kind of power than the power of earthly kingdoms. In a general audience at the Vatican, Pope Benedict XVI suggests
"The power of God's kingdom as embodied by Jesus' death isn't exclusively revealed by the resurrection, although the saving power of God is most apparent here. The magnitude of God's love for His creation in self-sacrifice shows Christ's real power as king. "
The ultimate love is the love that sacrifices self for another. This is the real power that defines Christ's kingdom. This is why evil can never ultimately triumph over good; evil avoids self-sacrifice. Evil always seeks what is best for the self over and against the other. It destroys the community and ultimately destroys itself.
On the other hand, self-sacrificing love is the ultimate Christian act where one falls into the opened arms of Christ on the cross, trusting in the power of God's ability to bring life from death. Christ's kingdom is not of this world, but it is for this world. Nothing is more important than conforming to this likeness of Christ as King.
