The Holy Ghost

The Holy Trinity: Father, Son and the Holy Ghost.

Mother + Father => Son or Daughter

No Son or Daughter without Father or Mother, right? Am I wrong in making the crazy assumption that the Holy Ghost is the Mother? Or was the mother just struck out of the equation and replaced by some mysterious Holy Ghost?

In Occult Theocracy by Lady Queenborough Edith Starr Miller, on page 73, it says:

Their Sovereign Lord God and Teacher bore the name of Hermes or Thoth, the Great Initiator. In him were typified the three great powers of royalty, law-giving or legislative and high priesthood which made the Greeks, disciples of the Egyptians, surname him Hermes Trismegistus or thrice great.

Only after the conquest of Egypt by the Hyksos (2000 B. C.) did the priests spread among the people the cult of Osiris and Isis and their son Horus.
