The Annunciation (anglicised from the Latin Vulgate Luke 1:36-39 Annuntiatio nativitatis Christi), also referred to as the Annunciation to the Blessed Virgin Mary or Annunciation of the Lord, is the Christian celebration of the announcement by the angel Gabriel to the Virgin Mary that she would conceive and become the mother of Jesus, the Son of God, marking his Incarnation. Gabriel told Mary to name her son Jesus, meaning "Saviour". Many Christians observe this event with the Feast of the Annunciation on 25 March, nine full months before Christmas, the birthday of Jesus. According to Luke 1:26, the Annunciation occurred "in the sixth month" of Elizabeth's pregnancy with John the Baptist.

Approximating the northern vernal equinox, the date of the Annunciation also marked the New Year in many places, including England, where it is called Lady Day. Both the Roman Catholic and Eastern Orthodox Churches hold that the Annunciation took place at Nazareth, but differ as to the precise location. The Basilica of the Annunciation marks the site preferred by the former, while the Greek Orthodox Church of the Annunciation marks that preferred by the latter.

Mother Mary Angelica of the Annunciation, PCPA (born Rita Antoinette Rizzo on April 20, 1923) is an American Roman Catholic nun who founded the Eternal Word Television Network. In 1944 she entered the Poor Clares of Perpetual Adoration, a Franciscan religious order for women, as a postulant, and a year later she was admitted to the order as a novice. She went on to found a new house for the order in 1962 in Irondale, Alabama, where the EWTN is headquartered, and in 1996 she initiated the building of the Shrine of the Most Blessed Sacrament and Our Lady of the Angels monastery in Hanceville, Alabama. Mother Angelica hosted shows on EWTN until she suffered a stroke in 2001. She continues to reside at the monastery in Hanceville.

The future Mother Angelica was born Rita Antoinette Rizzo, on April 20, 1923, in Canton, Ohio. She was the only child of John and Mae Helen Rizzo (née Gianfrancesco). Her father abandoned the family when Rita was very young, and her parents divorced in 1929. Her mother maintained full custody of Rita, but struggled with chronic depression and poverty. Her maternal grandparents kept Rita at times.
