To all devotees and friends,
This quote: (4) Fear not the unknown, for I am the unknown. (Madrian Literature Circle, ‘Intellect Against Intellectualism’, p. 2)
has been included under the heading Fragment of Lost Verses in The Eastminster Critical Edition of the Clear Recital, Version: ECE 3rd Edition. 
I knew that this missing verse from the Madrian Scriptures chimed with me. I bought this book from F.O.I. founder Olivia Robertson when I returned home from Burtonport. I have been searching and today rediscovered the relevant information:
“Fear not the unknown: for I am the Unknown. From Me riseth suns and their children the planets: and when suns reach their appointed time, I take them to Me in My dark embrace: for I am both Birth and Death. And the sun that loses its brightness in My Abyss, returns to greater life in other spheres: for I am Mistress of the Spheres. I am the space within each atom: from its heart I give birth to new galaxies. I take to Myself that which is to be transformed into greater life. So is it with yourselves. I need each sun, each tree, each one of you: for without the least of you My starry body is incomplete. I know you. Learn to know Me.”
~ excerpt from Oracle of the Goddess Nuit, from
“Dea, Rites and Mysteries of the Goddess,” by Olivia Robertson
The 1st edition of Dea, Rites and Mysteries of the Goddess has a date of 1980. https://www.stickfigurebooks.com/shop/stickfigure/031944.html
Personally, I have always doubted that “Fear not the unknown, for I am the unknown.” was actual Madrian Scripture but was rather speaking to the wider Pagan community.
To me, it resonates as Absolute Deity/Great Mother.
May Déa bless you. Blessed is She.
