It is often said that you cannot turn the clock back. In a sense, however, the Church does just that in her liturgy, in which we are inserted into Mysteries of our salvation which occurred millennia ago. At the beginning of Advent we revisited that age of yearning of the Prophets, when the parched earth seemed to groan with longing for the coming of a Messiah, whose arrival would transform the desert into a vibrant landscape of light and colour. On Christmas Day we gaze in wonder and joy on the babe in the manger, who contains within Himself the fulfilment of all the promises of the Old Testament.
