Prayer....
O Chosen One among the daughters of Adam, admirable Mary, the Son of God delights in your birth, for He beholds the one chosen to be His Mother, and oh! such a beloved Mother. May your birth give joy to my soul also, by obtaining from your divine Son the grace to be born again spiritually to a holy life, perfectly conformed to yours, so that I may merit to obtain eternal glory. Amen.
