According to J. Gordon Melton in the Encyclopedia of American Religions, it became "the most significant periodical in the Pagan movement during the 1970s and made Oberon Zell-Ravenheart, its editor, a major force in Neo-Paganism".
Margot Adler's sociological study Drawing Down the Moon: Witches, Druids, Goddess-Worshippers, and Other Pagans in America Today was first published in 1979, shortly after the first incarnation of Green Egg ceased.
"It took a catalyst to create a sense of collectivity around the word Pagan, and in the United States the Church of All Worlds and its Green Egg filled this role."
It was highly synergistic, bringing together hundreds of groups and ideas for debate in print, covering subjects relating to "ecology, ethics, tribalism, magic, science fiction, and the relationship of human beings to the planet".
