Costco issued an apology Wednesday, blaming the mistake on one of its distributors.

“Costco’s distributor mislabeled a small percentage of the Bibles, however we take responsibility and should have caught the mistake. We are correcting this with them for future distribution,” the statement said. “In addition, we are immediately relabeling all mislabeled Bibles. We greatly apologized for this error.”
