The child Jesus (the Santo Nino) has always been a reminder of the childlike simplicity that we should have when we approach God as our Father. In the Philippines, however, the child Jesus has also been portrayed wearing regal clothes, also reminding us of the divine kingship of Christ. That was the image of the child Jesus in the front facade of the Sto. Nino Parish.
The child Jesus has always been the more relate-able image of Jesus for me. In fact, when I teach children catechism, it would always be easier to explain to them how to live in a Christlike manner, by citing the anecdotes of the child Jesus in the Bible.
