'The liturgy enthusiastically celebrates Mary's Nativity and makes it one of the most appealing feasts of Marian devotion. We sing in today's Office: "Thy Nativity, O Virgin Mother of God, brings joy to the whole world, because from you came forth the Sun of Justice, Christ, our God."
Mary's birth is a prelude to the birth of Jesus because it is the initial point of the realisation of the great mystery of the Incarnation of the Son of God for the salvation of mankind. How could the birthday of of the Mother of the Redeemer pass unnoticed in the hearts of the redeemed?' (Divine Intimacy, Fr. Gabriel of St. Mary Magdalen)
