Apostolic order and unity

Summary

Searches were conducted across major official audiobook platforms (Audible, Google Play Books, Apple Books, Kobo, OverDrive, Hoopla, Libby) for an official, unabridged audiobook of "Apostolic Order and Unity" by Robert Bruce. The search results primarily pointed to physical book listings, reprint editions, and older archived versions of the text, such as on Archive.org, which are generally not official, commercially produced audiobooks. No direct evidence of an official, unabridged audiobook product for sale or available through the specified public library services was found on the targeted platforms or through general search queries. Therefore, an official audiobook is currently determined to be unavailable based on the search criteria.
