The Gospel of the Holy Twelve presents vegetarian versions of traditional teachings and events described in the canonical New Testament. The first collected volume was issued by The Order of At-One-Ment and United Templars Society-a publishing imprint which the author had established in 1881. The explanatory preface referred to an ancient source manuscript "preserved in the Monasteries of Thibet" which has never been produced or proven to exist. In subsequent editions, released during the early 1900s, the anonymous Editors revised their claim by stating that the text was "communicated" by departed mystics "in dreams and visions of the night".
