This name comes from the Latin word "cælum > cælestis", meaning “heavenly, coming from the sky, the blue color of the sky”. The name spread in a Christian context, used in relation to the Virgin Mary “Queen Mother in Heaven”. Queen of Heaven (Latin: Regina Caeli) is one of many Queen titles used of the Virgin Mary. The title derived in part from the ancient Catholic teaching that Mary, at the end of her earthly life, was bodily and spiritually assumed into heaven, and that she is there honored as Queen. Saint Celeste Metz was the 2nd Bishop of Metz and is revered as a saint by the Catholic Church, the Orthodox Churches and the Anglican Communion. Pope Celestine V was the head of the Catholic Church for a few months from 5 July to 13 December 1294 when resigned.
