Gavin Frost arose to fame when he and his wife, Yvonne Frost, formed the Church and School of Wicca in 1968/69. The pair advertised their courses heavily in magazines and assorted publications and had a reputation for controversy with respect to unsupported claims and endorsements of alleged incest and child sexual abuse.
Among the most controversial of unsupported claims made by the Frosts were that they were the founders of the Wiccan religion and that only they practiced true Wicca. The Frosts also claimed that they brought Wicca to the United States. In reality, Wicca was founded by Gerald Gardner and it has been widely established that Raymond Buckland was the first Wiccan initiate to bring the religion to the U.S.
Despite these vivid delusional fantasies, the most controversial actions of the Frosts involve their book, The Witches' Bible, first published in 1972 and now re-released with various altered titles, such as The Good Witches' Bible. In the book, the Frosts write about an initiation ritual involving sex with minors, only old enough to begin to display the first signs of secondary sex characteristics. Unfortunately, this may include children as young as ten years old. The Frosts also describe giving young girls wooden dildos, having their mother's break their hymens, and having young girls who experience pain using the dildos to be "helped" by their fathers. There was no further explanation given as to exactly what form of "help" the father was supposed to provide.
When controversy erupted over such blatant endorsement of child sexual abuse the Frosts responded by threatening to sue anyone who accused them of being pedophiles or pederasts.
For almost 20 years the Frosts kept this initiation ritual and defended it. Only later in the 1990s did they add a disclaimer saying that no one under the age of 18 should engage in sex during the ritual. However, all the remaining information about sex with minors was still kept intact.
Despite the controversy, the Frosts were very popular and active in the greater Wiccan community. To this day the couple has loyal followers who will defend them at all costs. Very few Wiccans have spoken out against them
Gavin Frost died on September 11, 2016, at age 86, and while suffering from numerous and undiagnosed medical conditions.
