The Birth of Christ has always been celebrated and hymned by Christians in some way or other, as it is central to the Faith. The Word of God in past times may have appeared as an angel of the Lord, or the divine fire of the burning bush, but now, from this time onwards, He has become one of us; and not just as a fully-grown man descended from Heaven, but in humility God is born of a woman, and comes to us as a tiny, speechless, infant. This is what is shown in the Nativity Icon, and around this central historical event other stories surrounding the birth of Jesus Christ are depicted.
