Unlike the traditional New Years image of the creaky old man representing the old year and the newborn baby the new, our old year Jesus is the enthroned, powerful ruler to whom is due all glory, honor and dominion. Because Christ dwells in eternity, he is forever at the peak of his mature strength, not vitiated by age.
As a matter of fact, Christ the Baby is not the mute, powerless infant for more than a passing moment - the short duration of the Christmas Season, because the Baby, too, lives in eternity - the already-not-yet of time. We should not make the mistake of seeing only his helplessness and tinyness. He is only apparently powerless. And yet kings will pay him homage and a king will fear him. In Catholic tradition we have an image of this Jesus. It is perhaps interesting that modern Catholicism has "lost" the image of the Infant of Prague - that tiny powerful Baby-King who unites the already and the not yet... probably because he became a statue too many people associate with the hallways of a Catholic School of the 1950's and 60's - strictly an image for children.
