This is an excerpt from The Infancy Narratives: Jesus of Nazareth, by Pope Benedict XVI:
Mary wrapped the child in swaddling cloths. Without yielding to sentimentality, we may imagine with what great love Mary approached her hour and prepared for the birth of her child. Iconographic tradition has theologically interpreted the manger and the swaddling cloths in terms of the theology of the Fathers. The child stiffly wrapped in bandages is seen as prefiguring the hour of his death: from the outset, he is the sacrificial victim, as we shall see more closely when we examine the reference to the first-born. The manger, then, was seen as a kind of altar.
Augustine drew out the meaning of the manger using an idea that at first seems almost shocking, but on closer examination contains a profound truth. The manger is the place where animals find their food. But now, lying in the manger, is He who called Himself the true bread come down from heaven, the true nourishment that we need in order to be fully ourselves. This is the food that gives us true life, eternal life. Thus the manger becomes a reference to the table of God, to which we are invited so as to receive the bread of God. From the poverty of Jesus’ birth emerges the miracle in which man’s redemption is mysteriously accomplished.
