The Zarathustrian Laws included variations of the trinity: 

• The Light of all light Ormazd, the Soul of all souls (the ghost of all things)
  • the Mother Almighty, the seen and unseen (created by Ormazd)
    • the Son, the Voice, Expression of things, All Speech, All Communion (created by Ormazd and Mother)

• Each and all created things have 3 attributes
  • the ghost, the soul, which is incomprehensible
  • the beast, the figure, the person, which is called individual
  • the expression, to receive and impart

The trinity in Oahspe is different than the trinity of Christianity, which is introduced later. The trinity of Christianity includes the Father, the Son, and the Holy Spirit, but for Oahspe’s trinity, (1) there is no separate Father and Holy Spirit because the Father IS the Spirit (the ghost of all things) and (2) the Mother is added, which represents the seen (corporeal) and the unseen (es’ean) worlds.
