There is no, one Holy Book in Wicca. There are several good, informative works on Wicca; including "Wicca: A Guide for the Solitary Practitioner" by Scott Cunningham, "The Spiral Dance" by Starhawk, "The Holy Book of Woman's Mysteries" by Z. Budapest or "The Witches' Bible: The Complete Witches' Handbook" by Janet and Stewart Farrar. The last one is NOT our "Bible", that's just the name and it is my favorite book about Wicca.
I recommend reading some of those, and other books about Wicca to get a good understanding of where our beliefs and morals come from.
The Simple answer is that Paganism does not have a Holy Book.
Paganism is an umbrella term to identify many ancient religions the 'Country Dwellers' believed in. These include Shamanism, Druidism, Asatru and Magick.
The original meaning of the word Pagan is 'Country Dweller'.
If Pagans had a holy book, it could be considered to be Nature itself. Most of Pagan lore comes from the human living with nature, and the transcendent knowledge of the wise men and women of those days.
A Pagan PerspectiveMost pagans do have a Book of Shadows, sometimes called a grimoire, in which we keep our rituals, rites, spells, words of inspiration, recipes, lists of materials, and any other pertinent information. As each pagan practices their path differently and ours is a "living" belief system" (changing, growing and staying current) a Book of Shadows is more often than not a "work in progress". In my personal Magical Library I have seven Books of Shadows of my own, three from my family tradition and six more from various outside sources. Each is different, what they all have in common is a deep reverence for Nature and respect for others.The Pagan "Bible" is called the Book of Shadows.
Paganism is an umbrella term for a variety of religions. Pagan religious lore goes as folklore and there is no need for written religious scripture in Pagan religions. The word Holy Book is not a valid term in the case of Pagan religions.
The Book of Shadows is like a personal journal and there is no one single "standard" Book of Shadows. Anyone can write their own Book of Shadows
For an example Asatru is considered as a Pagan religion, and a book was written in recent times called The Norse Mythologycontaining many beliefs of Asatru. But it is not the De Facto Holy Book of Asatru. People who follow the religion Asatru wouldn't even consider reading the Norse Mythology, because it is in their beliefs.
Paganism never had a holy book; it was based on an oral tradition. Books about paganism do exist; they are educational rather than venerated. There is no single book which is regarded as central to paganism. Even the term paganism is vague, since all it really means is a non-Christian religion formerly practiced in Europe, and there were several of those. No religion ever called itself paganism. Perhaps the Druids were the leading pagan religion, prior to the advent of a Christian Europe. There were also quite elaborate Norse and Celtic mythologies, which did have associated books, such as the Elder Edda (Norse) and the Mabinogion (Celtic).
With many branches of Polytheism, it is impossible to define them all in a single book. However, many have sacred books or texts.
There is no single holy book for Pagans. Pagans read many books, books written by other pagans.
One can say that the Holy book of Pagans is the Nature, Mother Earth.
