Saint January 1 : Solemnity of Mary Mother of God - a Title of Mary Ratified during the Council of Ephesus in 431
In the revised ordering of the Christmas period it seems to us that the attention of all should be directed towards the restored Solemnity of Mary the holy Mother of God. This celebration, placed on January 1 in conformity with the ancient indication of the liturgy of the City of Rome, is meant to commemorate the part played by Mary in this mystery of salvation. It is meant also to exalt the singular dignity which this mystery brings to the "holy Mother...through whom we were found worthy to receive the Author of life."(17) It is likewise a fitting occasion for renewing adoration of the newborn Prince of Peace, for listening once more to the glad tidings of the angels (cf. Lk. 2:14), and for imploring from God, through the Queen of Peace, the supreme gift of peace. It is for this reason that, in the happy concurrence of the Octave of Christmas and the first day of the year, we have instituted the World Day of Peace, an occasion that is gaining increasing support and already bringing forth fruits of peace in the hearts of many. (MC 5, 1974)
In the Bible, this is noted, when Mary visits her cousin Elizabeth she says:
Luke 1:39-45, Mary Visits Elizabeth 42 and exclaimed with a loud cry, "Blessed are you among women, and blessed is the fruit of your womb. 43 And why has this happened to me, that the mother of my Lord comes to me?"
