From Catholic News Service:
Archer, presenting The Gospel According to Judas by Benjamin Iscariot at a March 20 press conference in Rome, said he is a practicing Anglican who wanted his new book to be backed up by solid biblical scholarship.
So he convinced Father Francis J. Moloney, provincial of the Salesians in Australia and a former president of the Catholic Biblical Association of America, to collaborate.
Father Moloney, who served on the International Theological Commission for 18 years when it was under the presidency of the future Pope Benedict XVI, provided scholarly criticism of the text and wrote the bulk of the theological notes and clarifications found at the end of the book.
