“In spite of historical opposition and overt hostility between Mandaeans and Jews which goes back to almost 2000 years, and in spite of the still existing abomination in particular by the Mandaeans against some practices of the Jews — concerning circumcision and the worship of Adonai (the sun), the ancient Mandaeans had embraced Judaism or at least a large part of its teaching and tradition. This is an astonishing fact. In this book the author tries to explain on the basis of testimonies, evidence and resemblances how the Mandaeans could conceal the truth for a long time and how far they have succeeded in doing that.”
