Many Satanists attribute their conversions or discoveries of Satanism to "The Satanic Bible", with 20 percent of respondents to a survey by James Lewis mentioning "The Satanic Bible" directly as influencing their conversion. For members of the church, the book is said to serve not only as a compendium of ideas but also to judge the authenticity of someone's claim to be a Satanist. LaVey's writings have been described as "cornerstones" within the church and its teachings, and have been supplemented with the writings of its later High Priest, Gilmore, namely his book, "The Satanic Scriptures".
