‘’ In the light of this boundless benevolence and love, our exchange of Christmas greetings is yet another chance to respond to Christ’s new commandment: “Even as I have loved you, you must also love one another. By this all men will know that you are my disciples, if you have love for one another” (
Jn 13:34-35). Jesus does not ask us to love him in response to his love for us; rather, he asks us to love one another as he does. In other words, he asks us to become like him, since he became like us.
As Saint John Henry Newman prayed: “May each Christmas, as it comes, find us more and more like Him, who at this time became a little child for our sake, more simple-minded, more humble, more holy, more affectionate, more resigned, more happy, more full of God”.[[3]]

And he went on to say: “[Christmas] is a time for innocence, and purity, and gentleness, and mildness, and contentment, and peace”
[4].
This mention of Newman brings to mind his well-known words in his
Essay on the Development of Christian Doctrine , a book that coincided chronologically and spiritually with his entry into the Catholic Church: “Here below to live is to change, and to be perfect is to have changed often”.
[5]
Naturally, he is not speaking about changing for change’s sake, or following every new fashion, but rather about the conviction that development and growth are a normal part of human life, even as believers we know that God remains the unchanging centre of all things.[[6]]’’
