Reader Deacon Dave just alerted me that Amazon has delayed the release date of the Revised New Jerusalem Bible (RNJB) to August of 2020. Here is a link to the Amazon listing.
ChristianBook still reports a release date of April 9, 2019 on their product listing for the RNJB, but I suspect this will be delayed soon. The British publisher of the RNJB (Darton, Longman, and Todd) currently lists a publication date of June 2019.
I have sent an email to a contact at Darton, Longman, and Todd to request more information on when the bible is likely to be released. It’s quite possible that the currently-reported publication dates are merely estimates that depend on too many uncertain factors to nail down a firm date.
