Today is the Feast of the Maternity of the Blessed Virgin Mary

Second Sunday in October. The object of this feast is to commemorate the dignity of the Mary as Mother of God. Mary is truly the Mother of Christ, who in one person unites the human and divine nature. This title was solemnly ratified by the Council of Ephesus, 22 June, 431. The hymns used in the office of the feast also allude to Mary's dignity as the spiritual mother of men. The love of Mary for all mankind was that of a mother, for she shared all the feelings of her son whose love for men led Him to die for our redemption.
In the Roman Breviary the feast of the Maternity is commemorated on the second, and the feast of the Purity on the third, Sunday in October.
This glorious feast was established as a commemoration of the Third Ecumenical Council of the Church at Ephesus, in 431. It was set up for our own time in 1931 by Pope Pius XI, fifteen hundred years after the Council of Ephesus. The Catholic Church infallibly declares and defines the Divine Maternity of Our Lady. The Catholic Church tells us that in order to be saved we must believe with our full hearts that the same Person Who is the Son of God the Eternal Father in His Divine nature is also the Child of Mary the Virgin in His human nature. Anyone who refuses or hesitates to call Mary the Mother of God will never be saved.
