The Feast of the Birth of the Blessed Virgin Mary has been celebrated in the Church at least since the 8th Century.
In celebrating the nativity of Mary, Christians anticipate the Incarnation and birth of her Divine Son, and give honor to the mother of Our Lord and Savior.
Lord God,
the day of our salvation dawned
when the Blessed Virgin gave birth to your Son.
As we celebrate her nativity
grant us your grace and your peace.
Through Christ our Lord, Amen.
Things to do today:
1) Learn some hymns or prayers to Mary. Sing and recite some today!
2) Take flowers to a chapel or statue of Mary
3) Have a birthday party in honor of Mary. Teach someone else a little about her.
