<P> The Regina Coeli (Queen of Heaven) is an anthem of the Roman Catholic Church which replaces the Angelus at Eastertide (from Holy Saturday until the Saturday after Pentecost). It is named for its opening words in Latin . The Regina Coeli was the subject of numerous intonations throughout the centuries by known and unknown composers . Not all attributions are correct however, as an often quoted Regina Coeli by Joseph Haydn had other composers . Of unknown authorship, the anthem was in Franciscan use in the first half of the 13th century . Together with three other Marian anthems, it was incorporated in the Minorite Roman Curia Office, which the Franciscans soon popularized everywhere, and which by order of Pope Nicholas III (1277--1280) replaced all the older breviaries in the churches of Rome . </P> <P> The Catholic faith states, as a dogma, that Mary is assumed into heaven and is with Jesus Christ, her divine son . Mary should be called Queen, not only because of her Divine Motherhood of Jesus Christ, but also because God has willed her to have an exceptional role in the work of eternal salvation . Roman Catholicism employs the liturgical Latin phrase Ora Pro Nobis, meaning pray for us, and does not teach adherents to worship saints, but rather ask (asking is a form of prayer) those saints to pray for them . The encyclical Ad Caeli Reginam maintains that Christ as redeemer is Lord and King . The Blessed Virgin is Queen, because of the unique manner in which she assisted in our redemption, by giving of her own substance, by freely offering Him for us, by her singular desire and petition for, and active interest . Mary was chosen Mother of Christ so she might help fulfill God's plan in the redemption of humankind; The Catholic Church from the earliest times venerated the Queen of Heaven, according to Pius XII: </P> <P> From the earliest ages of the Catholic Church a Christian people, whether in time of triumph or more especially in time of crisis, has addressed prayers of petition and hymns of praise and veneration to the Queen of Heaven and never has that hope wavered which they placed in the Mother of the Divine King, Jesus Christ; nor has that faith ever failed by which we are taught that Mary, the Virgin Mother of God, reigns with a mother's solicitude over the entire world, just as she is crowned in heavenly blessedness with the glory of a Queen . </P> <P> The Queenship of Mary is commemorated in the last of the Glorious Mysteries of the Holy Rosary--the Coronation of the Virgin as Queen of Heaven and Earth . </P>
