Forbidden oracles?

"This book centers on The Gospel of the Lots of Mary, a previously unknown text preserved in a fifth- or sixth-century Coptic miniature codex. It presents the first critical edition and translation of this new text. My book is also a project about religious praxis and authority, as I situate the manuscript within the context of practices of and debates around divination in the ancient Mediterranean world."--Preface, p. [vii].
