And the Word became flesh
and made his dwelling among us
The Eternal Word who always with the Father from all eternity became a human person and lived among us. Because it was the Word who came he was the fullness of the revelation of God. Others, such as the prophets, had said things about God that were partial and fragmentary. But Jesus was the definitive word of God (see Hebrews 1:2), all God had to say, apart from which there was nothing to be said. Therefore the incarnation was an act of communication by a God who wanted to be known. But this wasn't a message that could be conveyed merely by a correct sequence of spoken or written words. It could only by conveyed by the specific shape of the individual human life of Jesus.
What came to be through him was life,
and this life was the light of the human race;
the light shines in the darkness,
and the darkness has not overcome it.
All things had been originally created through the Word who became flesh. And it was for this reason that, as flesh, he represented the pinnacle and perfection of all things. He was light, among other reasons, because he revealed the origin and destiny of women and men.
We are not some casual and meaningless product of evolution. Each of us is the result of a thought of God. Each of us is willed, each of us is loved, each of us is necessary.- Pope Benedict XVI
Jesus revealed that our life has a meaning that can't be explained away by scientific materialism, nor taken from us by dire circumstances, not even forfeit by our own mistakes, as long as we continue to repent.
But to those who did accept him
he gave power to become children of God,
to those who believe in his name,
who were born not by natural generation
nor by human choice nor by a man’s decision
but of God.
The only possible explanation for why it does not seem to matter to us or impress us that we are given the power to become children of God is that we've heard it to many times without really comprehending it. The nature Jesus had naturally from all eternity he shared with us by adoption. He opened the way for us to have a new and profound relationship with God the Father in the Holy Spirit. But we're down here thinking, 'How cute, children of God. What a lovely image'. Yet it is not meant to be a reduction to the static figure of a stained glass cherub. Jesus was, par excellence, Son of the Father. But the reaction he provoked from others was not, 'Aww', but rather awe. His Sonship made Peter exclaim, "Depart from me, for I am a sinful man, O Lord" (see Luke 5:8).
because while the law was given through Moses,
grace and truth came through Jesus Christ.
We are not, it is true, meant to become adult in the sense of being so self-sufficient as to not need God. But we are not meant to become so inept or infantile that we are unable to know truth or cooperate with grace. Becoming sons and daughters of the Father means having an increasingly strong belief in the truth and increasing confidence in the grace God never ceases to bestow. Growing into children of God transforms us from people motivated to obey God merely because of fear of transgressing the law into people who are genuinely excited to participate in the plan of God. The longer we live as disciples the more we should come to believe in the goodness of that plan. We don't tend to think of ourselves in the way John wrote of his audience. But he would probably say something similar to us:
But you have the anointing that comes from the Holy One,
and you all have knowledge.
I write to you not because you do not know the truth
but because you do,
We have been anointed by the Holy Spirit in baptism and confirmation. In the Catholic Church we have access to the fullness of truth, through the Scriptures, and distilled and organized into the teaching of the universal catechism. Let's stop cheapening what Jesus has done for us by recognizing how amazing it is and by living lives that more fully correspond to that gift.
