Book excerpt: This original and unusual book investigates a continuing Johannine apocalyptic tradition, represented in three strange Greek texts that are also linked to a Coptic manuscript. None of the Greek texts has been published in recent years, and they have never been published together or associated in studies of Christian apocrypha. John Court, well known for his studies on Revelation, supplies the text of the Greek manuscripts, with English translations, introductions and detailed explanatory notes that set the texts and their ideas in the context of Christian views on the future and the afterlife.
