"In the Christian system we have the Trinity of Father, Son and Holy Ghost; and it is interesting in this connection to note that in some of the old books the Holy Ghost is definitely mentioned as being feminine. Apart from this, the instinctive need of man to recognize the Divine Motherhood has in Christianity found expression in the cult of the Blessed Virgin, who, though not a Person of the Holy Trinity, is nevertheless the Universal Mother, the Queen of the Angels, the Star of the Sea."
