We have just heard in the Gospel the message given by the angels to the shepherds during that Holy Night, a message which the Church now proclaims to us: "To you is born this day in the city of David a Savior, who is Christ the Lord. And this will be a sign for you: you will find a babe wrapped in swaddling clothes and lying in a manger" (Lk 2:11-12). Nothing miraculous, nothing extraordinary, nothing magnificent is given to the shepherds as a sign. All they will see is a child wrapped in swaddling clothes, one who, like all children, needs a mother’s care; a child born in a stable, who therefore lies not in a cradle but in a manger. God’s sign is the baby in need of help and in poverty. Only in their hearts will the shepherds be able to see that this baby fulfils the promise of the prophet Isaiah, which we heard in the first reading: "For to us a child is born, to us a son is given; and the government will be upon his shoulder" (Is 9:5). Exactly the same sign has been given to us. We too are invited by the angel of God, through the message of the Gospel, to set out in our hearts to see the child lying in the manger.
God’s sign is simplicity. God’s sign is the baby. God’s sign is that he makes himself small for us. This is how he reigns. He does not come with power and outward splendour. He comes as a baby – defenceless and in need of our help. He does not want to overwhelm us with his strength. He takes away our fear of his greatness. He asks for our love: so he makes himself a child. He wants nothing other from us than our love, through which we spontaneously learn to enter into his feelings, his thoughts and his will – we learn to live with him and to practise with him that humility of renunciation that belongs to the very essence of love. God made himself small so that we could understand him, welcome him, and love him. […] The Son himself is the Word, the Logos; the eternal Word became small – small enough to fit into a manger. He became a child, so that the Word could be grasped by us. In this way God teaches us to love the little ones. In this way he teaches us to love the weak. In this way he teaches us respect for children. The child of Bethlehem directs our gaze towards all children who suffer and are abused in the world, the born and the unborn. Towards children who are placed as soldiers in a violent world; towards children who have to beg; towards children who suffer deprivation and hunger; towards children who are unloved. In all of these it is the Child of Bethlehem who is crying out to us; it is the God who has become small who appeals to us. Let us pray this night that the brightness of God’s love may enfold all these children. Let us ask God to help us do our part so that the dignity of children may be respected. May they all experience the light of love, which mankind needs so much more than the material necessities of life. […]
All this is conveyed by the sign that was given to the shepherds and is given also to us: the child born for us, the child in whom God became small for us. Let us ask the Lord to grant us the grace of looking upon the crib this night with the simplicity of the shepherds, so as to receive the joy with which they returned home (cf. Lk 2:20). Let us ask him to give us the humility and the faith with which Saint Joseph looked upon the child that Mary had conceived by the Holy Spirit. Let us ask the Lord to let us look upon him with that same love with which Mary saw him. And let us pray that in this way the light that the shepherds saw will shine upon us too, and that what the angels sang that night will be accomplished throughout the world: "Glory to God in the highest, and on earth peace among men with whom he is pleased." Amen!
