Today, on Christmas Day, we "welcome" Jesus into the world along with Christendom. This is a Jesus we already know, a man fully grown and with whom we are more than acquainted.
This isn't a baby we must perpetually welcome into our homes. In the rest of the Gospels, we are confronted instead with the adult Jesus.
Meeting this adult Jesus is difficult for many, and even frightens them to meet him as an adult and not a helpless, unassuming child, a God-man who need only be worshiped, not a master we are compelled to obey.
The adult Jesus scared the religious elites of his day because of what he asked, just as he scares the religious elites of today.
Jesus is an adult whom we must each decide whether to ignore, or to serve, as God intended us to do.
If we claim his name, and wish to be identified with it, we must not assume that admiring a baby in a manger is what God wishes. We must not delude ourselves that admiration - or even worship - is alone sufficient. We cannot ignore the adult Jesus, or prefer the baby instead of the adult.
The adult Jesus is hidden away by the religious elites. He scares them.
A fully human Jesus, fully grown, with a clearly understood, fully formed mission and a challenging religion of Good Works, scares them EVEN MORE!
So this adult Jesus isn't celebrated at Christmas. At all. And he rarely, if ever, makes an appearance the rest of the year, either.
So, just who is this Jesus?
Jesus, the adult, was of course born a baby, but he was born fully a human, of human parents, just as we were born. (He was recognized as such in the Gospels by his neighbors, by the Disciples, and by his parents.)
He grew in the knowledge of God and gained wisdom; he pleased God in all he did. When he became an adult, he was chosen at his baptism and anointed by God to be our Master, our Teacher, our Template and the Example of how a human being should live for the glory of God and most beneficially for our fellow human beings.
This Jesus is not the one created for us by Priests whom we must simply admire and worship from afar; unable to obey, unable to follow because he is so different, so distant, so alien.
We may instead celebrate the Jesus - a man called and chosen by God - whom we can fully love as our elder brother, and the one whom we can actively follow as our example in all things. We may become more like God because one of us has done it already, setting the example towards which we may strive.
Let us remember the birth, but also the adult life, of THIS Jesus, a Jesus worth celebrating on this Christmas Day, and every day.
